I want to get the co-ordinates of the ImageView
, Irrespective of device size.
Is there any possible way !!
I have tried to create specific size for the ImageView
,Even specific size for the Parent View
also ,but its not working.
I have tried the following possible ways.
int[] posXY = new int[2];
imageview.getLocationOnScreen(posXY);
int MoveX = posXY[0];
int MoveY = posXY[1];
I have tried with Matrix too ,But not working.
Matrix m = imageview.getImageMatrix();
Tried the below code, but it is also not working.!!
I need to get the same {x,y} Co-ordinates for all devices for the same point (Location).
final float[] getPointerCoords(ImageView view, MotionEvent e)
{
final int index = e.getActionIndex();
final float[] coords = new float[] {
e.getX(index), e.getY(index)
};
Matrix matrix = new Matrix();
view.getImageMatrix().invert(matrix);
matrix.mapPoints(coords);
return coords;
}
Here is draw Method :
if i set bitmap image in draw, it does not fit the screen for every devices. If i set image with Display width and height, i am getting different co-ordinates.
@Override
public void draw(Canvas canvas) {
// TODO Auto-generated method stub
super.draw(canvas);
Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.subimage);
mBitmap = ((BitmapDrawable) drawable).getBitmap();
canvas.drawBitmap(mBitmap, 0, 0, null);
}
Any Idea or help would be really helpful.
Finally found some relative solution,Same Co-ordinates for all devices.Using Activity,no Custom ImageView.
On ImageView OnTouch ..
public boolean onTouch(View v, MotionEvent event) {
int action = event.getAction();
final int index = e.getActionIndex();
final float[] coords = new float[] {
e.getX(index), e.getY(index)
};
Matrix matrix = new Matrix();
choosenImageView.getImageMatrix().invert(matrix);
matrix.mapPoints(coords);
return true;
}
Draw Using Canvas
Resources res = getResources();
Drawable drawable = res.getDrawable(R.drawable.image);
Bitmap bmp= ((BitmapDrawable) drawable).getBitmap();
alteredBitmap = Bitmap.createBitmap(bmp.getWidth(), bmp.getHeight(), bmp.getConfig());
canvas = new Canvas(alteredBitmap);
paint = new Paint();
paint.setColor(Color.GREEN);
paint.setStrokeWidth(5);
matrix = new Matrix();
canvas.drawBitmap(bmp, matrix, paint);
