Android的，无需XML布局添加新的视图 [英] Android, add new view without XML Layout

问题描述

我需要从人的经验性一点帮助。我希望这很容易。 我只是想表明新的视图（创建它的不 XML布局）以上主程序的观点。 这是整合AdMob.com广告代码：

I need a little help from people with expirience. I hope it's easy. I just want to show new View (creating it without XML layouts) above main program's view. It's to integrate AdMob.com ad block:

我写了这样code：

AdView ad = new AdView(this); 
ad.layout(10, 10, 100, 100); 
ad.setVisibility(View.VISIBLE); 
ad.bringToFront(); 
ad.requestFocus(); 
ad.invalidate();

正如你看到的 - 没有任何帮助，没有窗户可见
是什么让我的错误？ 谢谢！

As you see - nothing helped, no window visible
What do I make incorrectly? Thanks!

P.S。我在活动的的onCreate（捆绑）取得，但我想在其他地方了。

P.S. I made in in Activity's onCreate(Bundle), but I tried in other locations too.

推荐答案

您还没有真正告诉系统画什么或在哪里画它。你想看看您的活动为的setContentView（视图）的说明文件。如果你想获得此画在当前屏幕，看的对话框（和的setContentView 的说明文件）。

You haven't actually told the system to draw anything or where to draw it. You'll want to look at the documentation for setContentView(view) on your Activity. If you're trying to get this to draw over your current screen, look at the documentation for Dialog (and setContentView).

当我以编程方式创建任意的意见，以现有的布局中吸取，我通常会添加一个的FrameLayout 标签我的布局XML ，然后在code调用 findViewById（），那么我可以使用的FrameLayout 着眼于视图添加到（ addView（））。

When I'm programmatically creating arbitrary views to draw within an existing layout, I usually add a FrameLayout tag to my layout XML, then in the code call findViewById(), then I can use that FrameLayout view to add the view to (addView()).

我希望可以帮助一些没有写你的code你。

I hope that helps some without writing your code for you.
