I came across another post to help me. But when I use FlipLayout in my
view all I get it a black screen. However if I change the rotation
from 180 to 0 all is drawn ok. But I want my screen upside down. Whats
going on here?
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Matrix;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.LinearLayout;
public class FlipLayout extends LinearLayout {
private Matrix mMatrix = new Matrix();
private float[] mTemp = new float[2];
public FlipLayout(Context context, AttributeSet attr) {
super(context, attr);
mMatrix.postRotate(180);
}
@Override
protected void dispatchDraw(Canvas canvas) {
int sc = canvas.save();
canvas.setMatrix(mMatrix);
super.dispatchDraw(canvas);
canvas.restoreToCount(sc);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
final float[] temp = mTemp;
temp[0] = event.getX();
temp[1] = event.getY();
mMatrix.mapPoints(temp);
event.setLocation(temp[0], temp[1]);
return super.dispatchTouchEvent(event);
}
}
