Hello,
I got this code from another post and modified it to work for me as a
TextView. I tried using the code below but no transformation is
happening? Can someone help me out see what's wrong? I trying to
draw the canvas of the TextView with the given Matrix transformation.
Thanks!
Moto!
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Matrix;
import android.util.AttributeSet;
import android.view.MotionEvent;
import android.widget.TextView;
public class CTextView extends TextView
{
private Matrix mForward = new Matrix();
private Matrix mReverse = new Matrix();
private float[] mTemp = new float[2];
public CTextView(Context context) {
super(context);
mForward.postRotate(90);
mForward.invert(mReverse);
}
public CTextView(Context context, AttributeSet attrs) {
super(context, attrs);
mForward.postRotate(90);
mForward.invert(mReverse);
}
public CTextView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
mForward.postRotate(90);
mForward.invert(mReverse);
}
@Override
protected void dispatchDraw(Canvas canvas) {
canvas.save();
canvas.concat(mForward);
canvas.restore();
super.dispatchDraw(canvas);
}
@Override
public boolean dispatchTouchEvent(MotionEvent event) {
final float[] temp = mTemp;
temp[0] = event.getX();
temp[1] = event.getY();
mReverse.mapPoints(temp);
event.setLocation(temp[0], temp[1]);
return super.dispatchTouchEvent(event);
}
}
