我试图将此code得到一个视图的截图没有动作条：

I'm trying to apply this code to get a screenshot of a view without an actionbar:

 View main = findViewById(R.id.view);
Bitmap screenshot;
main.setDrawingCacheEnabled(true);
screenshot = Bitmap.createBitmap(main.getDrawingCache());
main.setDrawingCacheEnabled(false);

我的问题是我怎么能得到的观点，如果我们没有一个布局，视图设置，如：

My question is how i can get the view if we don't have a layout,the view is set like:

setContentView(new MyView(this));

请看一看这个项目：https://github.com/valerio-bozzolan/AcrylicPaint/blob/master/src/anupam/acrylic/EasyPaint.java任何帮助将是非常美联社preciated！

please take a look at this project: https://github.com/valerio-bozzolan/AcrylicPaint/blob/master/src/anupam/acrylic/EasyPaint.java Any help would be very appreciated!

更新：

我在显示java.lang.NullPointerException这行：

I got java.lang.NullPointerException at this line:

View v = new MyView(getBaseContext());
v.setDrawingCacheEnabled(true);
Bitmap cachedBitmap = v.getDrawingCache();
Bitmap copyBitmap = cachedBitmap.copy(Bitmap.Config.RGB_565, true); // <--- HERE

新年快乐！

推荐答案

如果您分配查看编程，那么你已经拥有了它：

If you're assigning the View programmatically, then you already have it:

View view = new MyView(context);
setContentView(view);

现在你可以画视图到位图的内容，无论你想保存它（搜索解决方案，我不要认为这是这个问题的一部分）。

Now you can draw contents of view into Bitmap and save it wherever you want (search for solutions, I don't think it's part of this question).
