Android で単純なリストを作成しようとしていますが、単純なアプリを実行するたびに同じエラーでクラッシュします。これがメインファイルの私のコードです
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);
}
}
私のxmlファイルは次のようなものです
<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>
今私がログ猫に入るエラーは.

このリソースが見つからないというエラーについてよく読んで、すべてのトリックを実行しましたが、うまくいきませんでした。R ファイルを削除し、プロジェクトをクリーンアップし、新しいプロジェクトを作成しましたが失敗しました。
