android实现截屏

private Bitmap shot(Activity activity) { //View是你需要截图的View View view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap b1 = view.getDrawingCache(); // 获取状态栏高度 / Rect frame = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; Log.i("TAG", "" + statusBarHeight); // 获取屏幕长和高 int width = activity.getWindowManager().getDefaultDisplay().getWidth(); int height = activity.getWindowManager().getDefaultDisplay().getHeight(); // 去掉标题栏 Bitmap b = Bitmap.createBitmap(b1, 0, 25, 320, 455); Bitmap b = Bitmap.createBitmap(b1, 0, statusBarHeight, width, height - statusBarHeight); view.destroyDrawingCache(); return b; }
