i am still facing a minor problem with this...
I created the view... But i donno where i should enter the xml layout
for it... Let me paste the code here... pls have a look n tell me what
to do ...
This is the initial code that will load a simple form
--------------------------------------------------------------------------------------
package hari.rts;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class supermarket extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button yes=(Button)findViewById(R.id.yes);
yes.setOnClickListener(onYes);
}
private View.OnClickListener onYes=new View.OnClickListener()
{
public void onClick(View v)
{
Intent i=new Intent(supermarket.this, List.class);
startActivity(i);
}
};
}
This is the layout for the above code (main.xml):
-------------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Welcome to the market"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Do you want to use the easy-shopping service?"
/>
<Button android:id="@+id/yes"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Yes"
/>
<Button android:id="@+id/no"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="No"
/>
</LinearLayout>
This is the 2nd form that gives a list of items with checkboxes:
--------------------------------------------------------------------------------------------------------------
package hari.rts;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.CheckBox;
public class List extends Activity
{
String i1;
String i2;
String i3;
String i4;
String i5;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.details);
final CheckBox checkbox1 = (CheckBox) findViewById(R.id.check1);
final CheckBox checkbox2 = (CheckBox) findViewById(R.id.check2);
final CheckBox checkbox3 = (CheckBox) findViewById(R.id.check3);
final CheckBox checkbox4 = (CheckBox) findViewById(R.id.check4);
final CheckBox checkbox5 = (CheckBox) findViewById(R.id.check5);
checkbox1.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks, depending on whether it's now
checked
if (((CheckBox) v).isChecked()) {
i1="item1";
}
else
{
i1="";
}
}
});
checkbox2.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks, depending on whether it's now
checked
if (((CheckBox) v).isChecked()) {
i2="item2";
}
else
{
i2="";
}
}
});
checkbox3.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks, depending on whether it's now
checked
if (((CheckBox) v).isChecked()) {
i3="item3";
}
else
{
i3="";
}
}
});
checkbox4.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks, depending on whether it's now
checked
if (((CheckBox) v).isChecked()) {
i4="item4";
}
else
{
i4="";
}
}
});
checkbox5.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// Perform action on clicks, depending on whether it's now
checked
if (((CheckBox) v).isChecked()) {
i5="item5";
}
else
{
i5="";
}
}
});
Button submit=(Button)findViewById(R.id.submit);
submit.setOnClickListener(onSubmit);
}
private View.OnClickListener onSubmit=new View.OnClickListener()
{
public void onClick(View v)
{
Intent j=new Intent(List.this, confirm.class);
j.putExtra("key1",i1);
j.putExtra("key2",i2);
j.putExtra("key3",i3);
j.putExtra("key4",i4);
j.putExtra("key5",i5);
startActivity(j);
}
};
}
This is the layout for the above file (details.xml):
-------------------------------------------------------------------------------------
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/
android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Thanks for choosing our service"
/>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Select the items you wish to buy"
/>
<CheckBox
android:id="@+id/check1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item1" />
<CheckBox
android:id="@+id/check2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item2" />
<CheckBox
android:id="@+id/check3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item3" />
<CheckBox
android:id="@+id/check4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item4" />
<CheckBox
android:id="@+id/check5"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Item5" />
<Button android:id="@+id/submit"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Submit"
/>
</LinearLayout>
This is finally the code where the custom View will be created n
displayed:
-------------------------------------------------------------------------------------------------------------------------
package hari.rts;
import android.app.Activity;
import android.content.Context;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
public class confirm extends Activity
{
String i,j,k,l,m;
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(new MyView(this));
i=getIntent().getExtras().getString("key1");
j=getIntent().getExtras().getString("key2");
k=getIntent().getExtras().getString("key3");
l=getIntent().getExtras().getString("key4");
m=getIntent().getExtras().getString("key5");
}
float getval1()
{
return 100;
}
float getval2()
{
return 200;
}
float getval3()
{
return 250;
}
float getval4()
{
return 300;
}
class MyView extends View
{
Paint paint = new Paint();
Paint paint1=new Paint();
float data1,data2,data3,data4;
public MyView(Context context)
{
super(context);
confirm activity = (confirm) context;
data1 = activity.getval1();
data2 = activity.getval2();
data3 = activity.getval3();
data4 = activity.getval4();
paint.setColor(Color.RED);
paint.setAlpha(255);
paint.setStrokeWidth(3);
paint1.setAlpha(230);
}
public void onDraw(Canvas canvas)
{
super.onDraw(canvas);
canvas.drawLine(data1,data2,data3,data4, paint);
//canvas.drawCircle(150, 200, 3, paint)
Bitmap bit =
BitmapFactory.decodeResource(getResources(),
R.drawable.pic1);
canvas.drawBitmap(bit,30,30,paint1);
canvas.drawText(i,10,10,paint);
canvas.drawText(j,20,10,paint);
canvas.drawText(k,30,10,paint);
canvas.drawText(l,40,10,paint);
canvas.drawText(m,50,10,paint);
}
}
}
The problem now is where i should enter the layout for the custom
View... If i give it in main.xml or details.xml,it crashes... If i
create a new xml file n give it there, the application crashes when
the custom view should be displayed... Please help me out with this
