android.view.InflateException: Binary XML file line #9: Error inflating class <unknown>
提问by vivatus
I've been looking into this issue for hours and similar errors that had solutions didn't do the trick.
我已经研究这个问题好几个小时了，但有解决方案的类似错误并没有解决问题。
I'm reusing this XML file for multiple ListViews in different activities (which I'm assuming has something to do with it) but I do not see why it would break. The XML file represents the individual items in the ListView.
我在不同的活动中为多个 ListView 重用这个 XML 文件（我假设这与它有关），但我不明白它为什么会中断。XML 文件表示 ListView 中的各个项目。
Here's the XML:
这是 XML：
<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"

</RelativeLayout>
</LinearLayout>
</LinearLayout>
</FrameLayout>
And here's the Java (error occurs on convertView = (FrameLayout) FrameLayout.inflate(mContext, R.layout.column_post, null);) :
这是 Java（在 convertView = (FrameLayout) FrameLayout.inflate(mContext, R.layout.column_post, null); 上发生错误；）：
@Override

JSONObject thePost = null;
String kind = null;
try {
thePost = mPosts.getJSONObject(position);
kind = thePost.getString("kind");
} catch (Exception e) {
System.out.println("errreoroer");
}
if (null == convertView) {
LayoutInflater inflater = (LayoutInflater) mContext

convertView = new FrameLayout(mContext);
if (Switches.getInMailView()) {

Thanks to @kiruwka, the problem is fixed!
感谢@kiruwka，问题已解决！
The issue was that I needed to make sure that I was using the same theme across activities.
问题是我需要确保我在活动中使用相同的主题。
回答by Larry Schiefer
I would use the inflator you grabbed from your context rather than the static method from FrameLayout, just to keep the code clear. FrameLayout's inherited inflate() method is just a wrapper around calling Context.getSystemService() then calling inflate. Try changing it to this:
我会使用您从上下文中获取的充气器，而不是来自 FrameLayout 的静态方法，只是为了保持代码清晰。FrameLayout 继承的 inflate() 方法只是调用 Context.getSystemService() 然后调用 inflate 的包装器。尝试将其更改为：
convertView =
(FrameLayout)inflater.inflate(mContext,
R.layout.column_post,
parent,
false);
I suspect the crash you are seeing is because you are passing null for the parent and the the default inflate() variant will attempt to attach the new child view you are creating to the parent (which you don't want to do.)
我怀疑您看到的崩溃是因为您为父级传递了 null，并且默认的 inflate() 变体将尝试将您正在创建的新子视图附加到父级（您不想这样做）。
