Android: Rotate image in imageview by an angle
Another simple way to rotate an ImageView:
UPDATE:
Required imports:
import android.graphics.Matrix;import android.widget.ImageView;Code: (Assuming imageView, angle, pivotX & pivotY are already defined)
Matrix matrix = new Matrix();imageView.setScaleType(ImageView.ScaleType.MATRIX); //requiredmatrix.postRotate((float) angle, pivotX, pivotY);imageView.setImageMatrix(matrix);This method does not require creating a new bitmap each time.
NOTE: To rotate an
ImageViewon ontouch at runtime you can set onTouchListener onImageView& rotate it by adding last two lines(i.e. postRotate matrix & set it on imageView) in above code section in your touch listener ACTION_MOVE part.
