As the title says, i am trying to use a custom view i have created and
initializing the size of it using the above xml code snippet located
inside my layout folder.:
<com.Resources.Gui.ScrollingText android:id="@+id/rss"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:layout_width="wrap_content" />
The height and width of my custom view doesnt seem to work. i have to
manualy hard code it to adjust and see my custom view using the bit of
code below located on my main activity class:
rssText = (ScrollingText) findViewById(R.id.rss);
rssText.setWidthHeight(200,50);
Code below is the ScrollingText methods.
Constructor:
public ScrollingText(Context context, AttributeSet attrs) {
super(context, attrs);
textPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
textPaint.setColor(Color.BLACK);
textBoxPaint = new Paint(Paint.ANTI_ALIAS_FLAG);
textBoxPaint.setColor(Color.WHITE);
textPaint.setTextSize(20);
}
public void setWidthHeight(int width, int height){
this.height = height;
this.width = width;
}
private void drawTextBox(Canvas c) {
// TODO: Experiment with these co-ordinates
c.drawRect(10, 0, width - 10, height, textBoxPaint);
}
private void drawTextRss(Canvas c) {
int textHeight = (int) textPaint.getTextSize();
printDebug("text height = "+ textHeight);
c.drawText(text, 10, height + 10, textPaint);
//c.drawText("Hello, why doesnt this work????????????", 10, 50,
textPaint);
}
@Override
protected void onDraw(Canvas canvas) {
// TODO Auto-generated method stub
super.onDraw(canvas);
drawTextBox(canvas);
drawTextRss(canvas);
setVisibility(VISIBLE);
}
@Override
protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec)
{
setMeasuredDimension(width,height);
}
I hope my explanations and code is enough to help me figure out how i
can set the size of the custom view from the xml layout file.
Not sure why android:layout_height="wrap_content"
android:layout_width="wrap_content" doesnt ??????
