Usage

From source file:Main.java

public static Bitmap getViewBitmap(View v) {
    v.setDrawingCacheEnabled(true);/*from   w w  w  . j  a  v  a  2s  .co m*/

    // this is the important code :)
    // Without it the view will have a dimension of 0,0 and the bitmap will
    // be null
    v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED),
            MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());

    v.buildDrawingCache(true);
    Bitmap bmp = Bitmap.createBitmap(v.getDrawingCache());
    v.setDrawingCacheEnabled(false); // clear drawing cache

    return bmp;
}
