主要Acitivity.java

package com.example.pc.doggie; 

import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 

public class MainActivity extends AppCompatActivity { 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
    } 

}

activity_main.xml中

<?xml version="1.0" encoding="utf-8"?>

public class List_Fragment extends ListFragment { 

    public List_Fragment() {

    } 

    @Override

     super.onActivityCreated(savedInstanceState); 

     setListAdapter(new ArrayAdapter<String>(this.getActivity(), android.R.layout.simple_list_item_1 
       , getResources().getStringArray(R.array.names))); 
    } 

}

list_fragment.xml

我做了但是我仍然得到相同的错误 – Mathunya

答

更改这个文件： list_fragment.xml

<ListView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/list" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"/>

你的片段从ListFragement延伸。这意味着你的片段布局必须有ID为android.R.id.list的ListView（以前它只是一个FrameLayout），所以现在它变成了一个ListFragment。 Android需要调用它的功能，所以它需要一个适当的ID在默认情况下的列表视图android.R.id.list

它的工作，谨慎解释为什么我需要改变它？ – Mathunya
