ビットマップクラスに対してこのようなものを試してください。
public class DrawBitmap extends View
{
Bitmap bitmap;
public DrawBitmap(Context content)
{
super(content);
bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.pic1);
}
@Override
protected void onDraw(Canvas canvas)
{
super.onDraw(canvas);
canvas.drawColor(Color.BLACK);//whatever color you want, make sure it's not the same as your image
canvas.drawBitmap(bitmap, (canvas.getWidth()), 0, null);
}
}
メインクラス
public class Main extends Activity
{
DrawBitmap myView;
@Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
myView = new DrawBitmap(this);
setContentView(myView);
}
}
