Android 截屏代码

/**

private Bitmap shot() {
    View view = getWindow().getDecorView();
    Display display = this.getWindowManager().getDefaultDisplay();
    view.setDrawingCacheEnabled(true);//允许当前窗口保存缓存信息，这样getDrawingCache()方法才会返回一个Bitmap
    Bitmap screenBmp = Bitmap.createBitmap(view.getDrawingCache());
    return screenBmp;
}
