在 Android 中，我试图制作简单的列表，但是每次我运行它时我的简单应用程序都会崩溃并出现相同的错误。这是我的主文件代码

package com.example.test;

import java.util.ArrayList;

import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.app.Activity;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        ListView lv=(ListView)findViewById(R.id.listView1);

        ArrayList<String> country=new ArrayList<String>();
        country.add("aaaaa");
        country.add("aaaaa");
        country.add("aaaaa");

        ArrayAdapter<String> adapter=new ArrayAdapter<String>(getApplicationContext(),R.id.listView1,country);
        lv.setAdapter(adapter);

    }



}

我的xml文件就像

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    tools:context=".MainActivity" >

    <ListView
        android:id="@+id/listView1"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentLeft="true"
        android:layout_alignParentTop="true"
        android:layout_marginLeft="28dp"
        android:layout_marginTop="47dp" >
    </ListView>

</RelativeLayout>

现在我在 log cat 中得到的错误是。

我读了很多关于这个资源未找到错误的内容，并且做了所有的把戏，但没有奏效。我删除了 R 文件，清理了项目，创建了新项目但失败了。

内部阵列适配器更改 R.id.listView1 为 android.R.layout.simple_list_item_1

ArrayAdapter<String> adapter=new ArrayAdapter<String>(getApplicationContext(),android.R.layout.simple_list_item_1,country);

将 ArrayAdapter 更改为：

ArrayAdapter<String> adapter=new ArrayAdapter<String>(MainActivity.this,android.R.layout.simple_list_item_1,country);
lv.setAdapter(adapter);
