Android截屏保存图片

记录:

/*** 1.获取和保存当前屏幕的截图*/private void GetandSaveCurrentImage(){//1.构建BitmapWindowManager windowManager &＃61; getWindowManager();Display display &＃61; windowManager.getDefaultDisplay();int width &＃61; display.getWidth();int height &＃61; display.getHeight();Bitmap Bmp;//2.获取屏幕View decorview &＃61; this.getWindow().getDecorView();decorview.setDrawingCacheEnabled(true);Bmp &＃61; decorview.getDrawingCache();// 获取状态栏高度Rect frame &＃61; new Rect();this.getWindow().getDecorView().getWindowVisibleDisplayFrame(frame);int statusBarHeight &＃61; frame.top;Log.i("TAG", "" &＃43; statusBarHeight);Bmp &＃61; Bitmap.createBitmap(Bmp, 0, statusBarHeight, width, height - statusBarHeight);//保存图片saveImageToGallery(this,Bmp,"share.png");}


/*** 2.保存图片到指定路径** &＃64;param context* &＃64;param bitmap 要保存的图片* &＃64;param fileName 自定义图片名称 getString(R.string.app_name) &＃43; "" &＃43; System.currentTimeMillis()&＃43;".png"* &＃64;return true 成功 false失败*/public static boolean saveImageToGallery(Context context, Bitmap bitmap, String fileName) {// 保存图片至指定路径String storePath &＃61; Environment.getExternalStorageDirectory().getAbsolutePath() &＃43; File.separator &＃43; "qrcode";Log.i("info","路径"&＃43;storePath);File appDir &＃61; new File(storePath);if (!appDir.exists()) {appDir.mkdir();}File file &＃61; new File(appDir, fileName);try {FileOutputStream fos &＃61; new FileOutputStream(file);//通过io流的方式来压缩保存图片(80代表压缩20%)boolean isSuccess &＃61; bitmap.compress(Bitmap.CompressFormat.JPEG, 80, fos);fos.flush();fos.close();//发送广播通知系统图库刷新数据Uri uri &＃61; Uri.fromFile(file);context.sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, uri));if (isSuccess) {return true;} else {return false;}} catch (IOException e) {e.printStackTrace();}return false;}

3.由于要对SDCard进行操作&＃xff0c;所以别忘记了在manifest.xml文件中赋以对SDCard的读写权限&＃xff1a;
