java.lang.IllegalArgumentException: x 一定要小于 bitmap.width()

获取屏幕截图,用裁剪图片创建位图的时候出现了错误,

先看看我的代码吧:

View v1 = mKittyBGLayer.getRootView();
    v1.setDrawingCacheEnabled(true);
    Bitmap source = v1.getDrawingCache();
    int width = source.getWidth();
    int height = source.getHeight();
    System.out.println("vListView : -"+vListView.getWidth());
    System.out.println("hListView : -"+hListView.getHeight());
    System.out.println("Width : -"+width);
    System.out.println("Height : -"+height);
    bitmap = Bitmap.createBitmap(source, vListView.getWidth(), 0, width, height - hListView.getHeight());

日志也看一下:

        11-01 11:00:31.429: I/System.out(1658): hListView :- 60
        11-01 11:00:31.429: I/System.out(1658): Width :- 480
        11-01 11:00:31.429: I/System.out(1658): Height :- 320

程序里面x < bitmap.getWidth也就是60 < 480

但是报错了

Bitmap createBitmap (Bitmap source, int x, int y, int width, int height)
x + width must equal or less than source.getWidth(), in your case, 60 + 480 > 480, so error occur.
