错误在这里:
ListAdapter adapter = new ArrayAdapter<String>(
this,
R.layout.conversation_item,
chatList
);
getListView().setAdapter(adapter);
当我删除它时没有错误.
No error when I remove it.
ListAdapter adapter = new ArrayAdapter<String>(
this,
R.layout.conversation_item,
chatList
);
getListView().setAdapter(adapter);
请问有什么解决办法?

推荐答案
我很确定问题出在您的 conversation_item 布局上.docs 规定您必须为资源提供单个 文本视图.这种布局是什么样的?
I'm pretty sure the problem lies in your conversation_item layout. The docs state that you must provide a resource with a single TextView. What does that layout look like?
举个例子，这是 simple_list_item_1 布局的样子，你的应该非常相似.
As an example, this is what the simple_list_item_1 layout looks like, yours should be pretty similar.
<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textAppearance="?android:attr/textAppearanceLarge"
android:gravity="center_vertical"
android:paddingLeft="6dip"
android:minHeight="?android:attr/listPreferredItemHeight"
/>
我刚刚编辑了问题，以便显示您的布局.您的布局确实是错误的，如果您使用该构造函数，则无法在那里使用线性布局.您可以使用其他构造函数( ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects) )并提供您的自定义布局和 TextView 的 id.
I just edited the question so your layout will show. Your layout is indeed wrong, you cannot have the linear layout there if you're using that constructor. You can use the other constructor ( ArrayAdapter(Context context, int resource, int textViewResourceId, T[] objects) ) and provide your custom layout and your TextView's id.
这篇关于您必须为 TextView android 错误提供资源 ID的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
