推荐答案

这是选择可能是有一个的FrameLayout有两个孩子，第一个SurfaceView，那么不管你想要覆盖的SurfaceView。在下面的示例中，的FrameLayout第二种观点是有一个按钮和一个TextView一个horozontil的LinearLayout。该的FrameLayout显示其作为所有在底部堆在Z序的第一个孩子，并定位在左上角的所有儿童。在这种情况下的LinearLayout有Gravity.CENTER_VERTICAL（我想你可以做同样的事情上的LinearLayout填充。

An option may be to have a FrameLayout with two children, first the SurfaceView, then whatever you want to overlay on the SurfaceView. In the sample below, the second View in the FrameLayout is a horozontil LinearLayout with a Button and a TextView. The FrameLayout displays all its children as piled in Z order with the first child at the bottom and all children positioned at the upper left corner. In this case the LinearLayout has Gravity.CENTER_VERTICAL (I think you could do the same thing with padding on the LinearLayout.

我从来没有发现有关如何SurfaceViews多少（好）的文件（或任何屏幕绘图）的作品。可能有闪烁或刷新的一个问题，但我没有看到我的Froyo埃沃太大的问题。 （此测试应用程序借鉴了按钮下面的SurfaceView和TextView的捻转行。

I have never found much (good) documentation about how SurfaceViews (or any of the screen drawing) works. There may be a problem with flickering or refresh, but I don't see much problem on my Froyo Evo. (This test app draws 'twirling' lines on the SurfaceView below the Button and TextView.

如果问题很简单：你如何编程一个TextView添加到是由XML创建的布局充气布局的话，得到的布局实例的引用，并调用addView（）把它

If the question is simply: How do you programmatically add a TextView to a Layout that was created by a XML inflated Layout, then, get a reference to the Layout instance and call addView() to it.

Layout lay = parentLayo.findViewById(R.id.drawingSurfaceParent);
TextView tv = new TextView(this);
tv.setText("New textview");
lay.addView(tv);
