Set Original Size initially about touchimageview HOT 6 CLOSED

Quite simple:
Remove the lines 216-219:

        float scaleX = (float) viewWidth / (float) bmWidth;
        float scaleY = (float) viewHeight / (float) bmHeight;
        scale = Math.min(scaleX, scaleY);
        matrix.setScale(scale, scale);

and put them on a new method that is called between the lines 102-103 (only the first time).

if (xDiff < CLICK && yDiff < CLICK) {
      newMethod();
      performClick();
}

from touchimageview.

I did that and the following lines are giving error:

        float redundantYSpace = (float) viewHeight - (scale * (float) bmHeight) ;
        float redundantXSpace = (float) viewWidth - (scale * (float) bmWidth);
        redundantYSpace /= (float) 2 ;
        redundantXSpace /= (float) 2;

I suppose that is a NullPointerException. Put before those lines:
scale = 1;
to say that it is not scaled at the begining

from touchimageview.

Setting scale = 1 solved the problem but causes a new one. The image now only appears when I touch the screen and it floats at the bottom of the screen.

I solved the problem. Instead of removing lines 216-219, I kept them and added 2 lines of code:

        float scaleX = (float) viewWidth / (float) bmWidth;
        float scaleY = (float) viewHeight / (float) bmHeight;
        float scaleZ =1f;
        scale = Math.min(scaleX, scaleY);
        scale = Math.min(scale, scaleZ);
        matrix.setScale(scale, scale);

from touchimageview.

This issue will be fixed when scaleTypes are supported. You could then set the scale type to "center" in xml. Closed as another open issue deals with supporting scale types.
