[android-developers] Custom view for Tablayout's items
Hi everyone! I created a custom view for TabLayout items, where I have a pictured and the text below it (ImageButton + TextView). Original tabs have only text and when you tap on one tab, you can see some fade effect by default in gray color which gives you the feeling that you tapped on the tab. Since I made the custom view for tabs, the fade effect is still there, but only when I click somewhere around the picture layer and not when I hit the picture layer. The fragment is switched because I made the click event that switches to proper fragment, because by default the switch wasn't working while clicking on imageButton.

[android-developers] Custom view rendering issue
Hi, I am writing a custom view and for optimization purposes, I draw some static part of the view in a Bitmap. Unfortunately, the quality of the rendering when using an offscreen bitmap is noticeably less compared to rendering into the view's canvas bitmap. Here are two screenshots showing the difference Rendering into view's Canvas: https://lh5.googleusercontent.com/-wSjtLmhUgz8/UQZV96LTo6I/AEM/r9saff_8dlM/s1600/01_view_canvas.png Rendering into a Bitmap Canvas https://lh3.googleusercontent.com/-jVuFcXhAf7g/UQZWK7NBNfI/AEU/0AfCGfQMudU/s1600/02_bitmap_canvas.png The difference is most noticeable at the horizontal black line. The anti-aliasing algorithm seems to affect more pixels (is wider). The drawing code is the same in both cases, and the offscreen canvas is created like this final Bitmap tempBitmap = Bitmap.createBitmap(getWidth(), getHeight(), Bitmap.Config.ARGB_); final Canvas tempCanvas = new Canvas(tempBitmap); Any ideas on how to get the same rendering in the offscreen canvas as in the view's ?

[android-developers] Custom View
Hello all, I'm working on a custom view and I have some problems trying to define some custom XML attributes. Here is part of my definitions: declare-styleable name=ViewUpDown attr name=step format=float / attr name=value format=float / attr name=unit format=string / attr name=title format=string / /declare-styleable declare-styleable name=ViewSelect attr name=items format=string / attr name=title format=string / /declare-styleable 1- Both have the attribute title, they are distinct view so I think The is no conflit but is. I get an error that says title has already defined on the second title. 2- the attribute items on ViewSelect should be a string array? I tried some options like: string-array or string[], but none worked. I been looking for a list of valid options but without luck. Any tip?

Hi,
What underlying bitmap are you referring to? In the onDraw() method, the
Canvas is used to draw onto your application's window buffer.

[android-developers] Custom View with Children Implemented onGestureListener
Hi,
I have a custom View with Children and it has also implemented
OnGestureListener. In custom view class I have also overridden
onSingleTapUp() function as below.
@Override
public boolean onSingleTapUp(MotionEvent e) {
// TODO Auto-generated method stub
return false;
}
How I will Intercept this Tap action from my MAIN ACTIVITY class when I tap
on any child of custom view?
Thanks in advance for your explanation. Please give some example or pointer.

[android-developers] Custom View
Afternoon All, I am working on trying to streamline my app a bit and i want to get the most out of my custom view and the xml layout. So I have a custom object with 4 images and a textview in the whole view, I have created functions to inject the images I want to use in code, but I am looking to do something like the following: customView image1Property.src ='img;/ I may not be too clear and for that I apologize for now.

Re: [android-developers] Custom View
Here is a nice example that you can refer to. http://blog.pocketjourney.com/2008/05/02/android-tutorial-42-passing-custom-variables-via-xml-resource-files/ There is also an official sample which I guess needs a bit of modification (I am not sure, don't remember) It's in the samples of the API level 8. the class is called CustomView1.java.

[android-developers] custom view does not display properly after closing and reloading app
I am having trouble with a custom view displaying properly. When the
view is first loaded (meaning the app is not cached in memory), the
view displays OK. However, when the app is closed with the back
button and then reloaded, the view is a black screen and does not
display as intended. The view looks something like as follows.
Basically, what happens is the constructor starts a timer which only
stops when the view functions getHeight() and getWidth() are non-
zero. The actual values for the screen height and width are needed by
the draw function. What can I do to get the following view to draw
when the app is reloaded.
public class CustomView extends View {
private volatile boolean initializationDone = false;
private Timer initializationTimer;
public CustomView(Context context) {
super(context);
initializationDone = false;
// do some other stuff here
initializationTimer = new Timer();
initializationTimer.scheduleAtFixedRate(new
InitializationHelper(),
50, 50);
}
private class InitializationHelper extends TimerTask {
private volatile boolean timerCancelled = false;
public void run() {
if ((CustomView.this.getHeight() 0)
(CustomView.this.getWidth() 0)) {
if (!timerCancelled) {
timerCancelled = true;
if (initializationTimer != null) {
initializationTimer.cancel();
initializationTimer.purge();
}
// do some more initialization here
initializationDone = true;
}
postInvalidate();
}
}
}
@Override
public void onDraw(Canvas canvas) {
super.onDraw(canvas);
if (!initializationDone) {
return;
}
// draw stuff here
}
}
I have tried replacing the timer with the following, I still do not
see the view display after starting the app again just after being
closed. (It does display properly when the app is loaded fresh into
memory with the following).
@Override
protected void onSizeChanged (int w, int h, int oldw, int oldh) {
if ((w = 0) || (h = 0))
return;
initializationDone = true;
postInvalidate();
}
Any ideas?

[android-developers] custom view onDraw() in layout xml not called
hi all android gurus,
I recently started android programming and stuck on custom views
I have seen a number of posts similar to me with some tips,
suggestions etc
but none worked for me
heres my problem
I have my main activity defined in main.xml which has got a button to
display another activity
which is something like
LinearLayout android:id=@+id/LinearLayout01
android:layout_width=fill_parent android:layout_height=fill_parent
xmlns:android=http://schemas.android.com/apk/res/android;
android:orientation=vertical
View class=android.pvee.vm.animateview android:id=@+id/
animateview01 android:layout_gravity=top android:layout_weight=1
android:background=@drawable/vmquad
android:layout_width=fill_parent
android:layout_height=fill_parent/View
TableLayout android:id=@+id/TableLayout01
android:layout_height=wrap_content
android:layout_width=fill_parent
TableRow android:id=@+id/TableRow01
android:layout_height=wrap_content
android:layout_width=fill_parent
android:gravity=center_horizontal
Button android:id=@+id/Button01 android:layout_width=wrap_content
android:layout_height=wrap_content android:text=Home/Button
...
...
/TableRow
/TableLayout
/LinearLayout
in manifest file I declared above activity as activity
android:name=.activity name /
and for the button click
btnStart.setOnClickListener(new Button.OnClickListener() {
public void onClick (View v){
Intent animate = new Intent(v.getContext(),
activity
name.class);
startActivityForResult(animate, 0);
}
I have custom view class animateview which overrides ondraw
public class animateview extends View {
public animateview(Context context, AttributeSet attrs) {
super(context, attrs);
Log.i(animateview, in constructor);
}
/* @Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
Log.i(animateview, in on measure);
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
setMeasuredDimension(getMeasuredWidth(), getMeasuredHeight());
}*/
@Override
protected void onDraw(Canvas canvas) {
Log.i(animateview, in draw + canvas.toString());
canvas.drawText(this is a test, 20, 10, null);
}
}
but when this activity is called onDraw never called..or onMesure
I have overridden onMeasure to set size but It didnt work...
and I put log message in the constructor of this class - didnt work
but when this activity is called the custom view background image is
drawn by the layout which is set in above xml
any tips would be greatly appreciated..I can post more details or code
snippet if u want
thanks in advance
regards
pvee

Re: [android-developers] Custom View as Gallery Item
That should work.
Media media = medias.get(index);
if (convertView == null) {
LayoutInflater inflater = (LayoutInflater) context
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
convertView = inflater.inflate(R.layout.media_adapter, null,
true);
}
ImageView img = (ImageView)
convertView.findViewById(R.id.mediaImage);
img.setImageBitmap(media.getBmp());
img.setLayoutParams(new LayoutParams(53, 53));
Something like this. I am not sure why isn't it working. Maybe, it is being
diaplyed, but you have to adjust the layout a bit.

[android-developers] Custom View orientation change
I have a custom view A which extends RelativeLayout and internally uses 3 instances of custom view B: B1, B2 and B3, which can be 'flung' left or right to move to B4, B5 and B6. I want to resize the whole view based on the orientation. I have hardcoded the size of B based on the screen width of 320 (if the view is initialized in potrait mode), or 480 (landscape mode), and then use the screen density from getDisplayMetrics() to convert them into real pixel values to draw my view. Is this is best way to do it? I was trying to use onSizeChanged to look for orientation changes, but this does not work because onMeasure() is called before onSizeChanged() and the orientation change does not show up.

[android-developers] Custom view, instantiated in XML, overridden onDraw, canvas size outside allocated space.
Hi,
I've got a custom class being loaded up by my layout XML, and drawing
to the screen. This much works perfectly.
First some background: In my main layout XML I define a tabhost,
linearlayout, framelayout and tabwidget. Following on from this, each
activity has its own layout XML that defines how its UI is laid out
inside the parent framelayout when the activities are launched by
selecting a tab.
The problem comes when I try to draw a line at the bottom of the
canvas in the overridden onDraw(Canvas) function in my custom view
(class CompassView extends View); it is drawn underneath the tabwidget
defined in the main parent XML!
I fetch the size of the canvas with canvas.getHeight(). The value it
returns seems to include the space underneath the tabwidget, but not
the space occupied by the notification bar at the top. Note that my
tabwidget is at the bottom of the screen.
Here is the layout for the child view which sits inside the
framelayout of the parent XML:
?xml version=1.0 encoding=utf-8?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:id=@+id/compass
android:orientation=vertical
android:layout_width=fill_parent
android:layout_height=fill_parent
com.tjhowse.geoloc.CompassView
android:layout_width=fill_parent
android:layout_height=fill_parent/
/LinearLayout
At the start of the constructor for my custom view:
public CompassView(Context context, AttributeSet attrs) {
super(context, attrs);
setLayoutParams(new LayoutParams(context, attrs));
...
I would've thought the fill_parent attribute would've prevented the
view, and thus the canvas, from overlapping with the tabwidget. If I
replace my custom class with:
Button android:id=@+id/pbTest
android:layout_width=wrap_content
android:layout_height=fill_parent
android:text=BUTAN OMG /
...the button correctly fills the available space, and has a proper
bottom edge that clearly finishes before it intersects the tabwidget.
Any thoughts?
Thanks,
tjhowse.

[android-developers] Custom view disappears, when scrolling
Hi.
I wrote a custom view for ListView rows. It works fine, but when I
scroll it, all views in the list disappears.
This this how I draw my view:

//poster
if(poster != null)
canvas.drawBitmap(poster, padding, padding, paint);
//title
canvas.drawText(title, 55 + padding, 16 + padding, paint);
}
Any suggestions, how to fix this?

Re: [android-developers] Custom view disappears, when scrolling
did u set cachecolorhint to #0
when u scroll if a black screen will appear, if u don't set as above. My
guess is drawn and its masked by the black background of listview when it
scrolls.
can u put some logs to see if ur method is actually called .

Hi.
I wrote a custom view for ListView rows. It works fine, but when I
scroll it, all views in the list disappears.
This this how I draw my view:
@Override
protected void onDraw(Canvas canvas) {
//poster
if(poster != null)
canvas.drawBitmap(poster, padding, padding, paint);
//title
canvas.drawText(title, 55 + padding, 16 + padding, paint);
}
Any suggestions, how to fix this?

[android-developers] Custom View using XML layout EditTexts: SavedState conflict
I'm trying to figure out how to properly make a custom view consisting
of a LinearLayout and some children, one of which is a EditText. To
make this simple, I've pared down the code to the simplest possible
case.
res/layout/bughunt.xml is a basic definition of a custom view; it's
just a layout with a single EditText inside.
?xml version=1.0 encoding=utf-8?
LinearLayout xmlns:android=http://schemas.android.com/apk/res/
android
android:orientation=horizontal
android:gravity=center_vertical
android:layout_width=wrap_content
android:layout_height=wrap_content
EditText
android:id=@+id/text1
android:layout_width=wrap_content
android:layout_height=40sp
android:gravity=center
android:width=50sp
android:singleLine=true/
/LinearLayout
My custom view class:
public class BugHunt extends LinearLayout {
public BugHunt(Context context) {
super(context);
initLayout(context);
}
public BugHunt(Context context, AttributeSet attrs) {
super(context, attrs);
initLayout(context);
}
private void initLayout(Context context) {
LayoutInflater i = (LayoutInflater) context.getSystemService
(Context.LAYOUT_INFLATER_SERVICE);
i.inflate(R.layout.bughunt, this);
}
}
Then I put two instances like the following in an Activity layout
file:
my.package.BugHunt
layout_width=wrap_content
layout_height=wrap_content /
The problem I'm having is when the EditTexts save state, they
overwrite each other's state. To reproduce this, put two or more
instances of BugHunt into an Activity, run it, and enter some
(different) text into each EditText. Then, switch the screen
orientation. After the layout is redrawn, all EditTexts will have the
same text in them (the text from whichever EditText saved state last).
I can only guess that I'm not using the LayoutInflater properly. Any
ideas?

Hi. I need to develop some widget like a standard Gallery. On visible part of the screen should be three images. Images may be scrolled up and down or left and right in dependence on orientation.

[android-developers] Custom view - canvas height incorrect?
To simply debugging of my custom View, I'm trying to draw a border
around it so I can see its exact size/position.
The left and right sides of the border draw correctly, but the top and
bottom end up outside the screen by about 50 pixels.
My guess is that canvas.getHeight() isn't accounting for the
notification bar at the top. What am I doing wrong?
Here's my code:
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
Log.w(, canvas bounds: + canvas.getClipBounds() + , width/
height: + canvas.getWidth() + , + canvas.getHeight());
//draw border
canvas.drawLine(0, 0, canvas.getWidth(), 0, mBorderPaint);
canvas.drawLine(canvas.getWidth(), 0, canvas.getWidth(),
canvas.getHeight(), mBorderPaint);
canvas.drawLine(canvas.getWidth(), canvas.getHeight(), 0,
canvas.getHeight(), mBorderPaint);
canvas.drawLine(0, 0, 0, canvas.getHeight(), mBorderPaint);
}
Here's the output of the log statement:
10-24 02:01:35.488: WARN/(1300): onDraw called: canvas bounds:Rect(0,
0, 320, 430), width/height: 320, 480
