Android 针对View的截图操作

    实现对View的截图操作,核心代码如下:

		Bitmap bitmap = null;
		FileOutputStream fileOutputStream = null;
		try {
			
			bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), Config.ARGB_8888);
			Canvas canvas = new Canvas();
			canvas.setBitmap(bitmap);
			view.draw(canvas);
			
			fileOutputStream = new FileOutputStream(filePath);
			bitmap.compress(CompressFormat.PNG, 100, fileOutputStream);

		} catch (Exception e) {
			e.printStackTrace();
		} finally {
			if (bitmap != null && !bitmap.isRecycled()) {
				bitmap.recycle();
				bitmap = null;
			}
			if (fileOutputStream != null) {
				try {
					fileOutputStream.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}

     例如:对整个窗口进行截图,可以使用下面代码获得窗口的View:

View windowView = (View) getWindow().getDecorView();

     多说一句:希望对您有所帮助!:)
