Hi There,
I have created a simple custom view to display a line and added it to
the LinearLayout.
the custom view is displayed on Screen, the other view following the
cusomview never show up on Screen.
Thanks
here is the code:
from the code, I have added a CheckBox to LinearLayout after adding
CustomView
package android.test.custom;
import android.app.Activity;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.os.Bundle;
import android.view.View;
import android.widget.CheckBox;
import android.widget.LinearLayout;
import android.widget.LinearLayout.LayoutParams;
public class Test extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle icicle) {
super.onCreate(icicle);
//setContentView(R.layout.main);
LinearLayout ll = new LinearLayout(this);
ll.addView(new CustomView(this),new
LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
ll.setOrientation(LinearLayout.VERTICAL);
ll.addView(new CheckBox(this),new LinearLayout.LayoutParams(
LayoutParams.FILL_PARENT, LayoutParams.WRAP_CONTENT));
setContentView(ll);
}
class CustomView extends View
{
public CustomView(Context ctx)
{
super(ctx);
}
/* (non-Javadoc)
* @see android.view.View#onDraw(android.graphics.Canvas)
*/
@Override
protected void onDraw(Canvas canvas) {
super.onDraw(canvas);
canvas.save();
Paint p = new Paint();
p.setColor(Color.WHITE);
canvas.drawLine(0, 0, 100, 0, p);
canvas.restore();
}
}
}
