对当前Activity进行截屏的封装代码

// 获取指定Activity的截屏，保存到png文件 private static Bitmap takeScreenShot(Activity activity) { // View是你需要截图的View View view = activity.getWindow().getDecorView(); view.setDrawingCacheEnabled(true); view.buildDrawingCache(); Bitmap bitmap = view.getDrawingCache(); // 获取状态栏高度 Rect frame = new Rect(); activity.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame); int statusBarHeight = frame.top; System.out.println(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(bitmap, 0, statusBarHeight, width, height - statusBarHeight); view.destroyDrawingCache(); return b; } // 保存到sdcard private static void savePic(Bitmap b, String strFileName) { FileOutputStream fos = null; try { fos = new FileOutputStream(strFileName); if (null != fos) { b.compress(Bitmap.CompressFormat.PNG, 90, fos); fos.flush(); fos.close(); } } catch (FileNotFoundException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } } public static void shoot(Activity activity) { ScreenShot.savePic(ScreenShot.takeScreenShot(activity), 'sdcard/apic/image' + System.currentTimeMillis() + '.png'); } } </pre>
