Hi All,
I am trying to add a button to a custom imageview. I have created a
custom view to display an image to the screen, now i wanted to add a
custom button on this veiw and display a layout in onClick. The
following is my custom view.
/** testimgview.java*/
package com.android.testview;
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.graphics.Rect;
import android.util.Log;
import android.view.ImageView;
public class testimgview extends ImageView {
private static final boolean DEBUG = true;
private Bitmap sourceImage;
private int pWidth, pHeight;
private float x, y;
public testimgview(Context context) {
super(context);
BitmapFactory.Options bfo = new BitmapFactory.Options();
bfo.inPreferredConfig = Bitmap.Config.RGB_565;
sourceImage = BitmapFactory.decodeResource( getResources
() ,R.drawable.img, bfo);
}
}
@Override
protected void onDraw(Canvas canvas)
{
x = getWidth()*1.0f / pWidth;
y = getHeight()*1.0f / pHeight;
canvas.drawBitmap( sourceImage, null , new Rect(0,0,getWidth
(),getHeight()),tmpPaint);
for (int i = 0; i < eyesMidPts.length; i++)
{
canvas.drawCircle(x, y, 10.0f ,..);
}
}
}
/**testview.java*/
package com.android.testview;
import android.app.Activity;
import android.os.Bundle;
public class testview extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
testimgview test = new (this);
setContentView(test);
}
}
