我是Android開發人員中的新成員。 I'm執行的應用程序，但it's給我的錯誤：可惜的是， 'APP_NAME' 已停止不幸的是，'app_name'已停止
我的代碼：
MainActivity
public class MainActivity extends ActionBarActivity {
private ListView lista;
//array de datos
private String[] datos = {"Item uno","Item dos","Item tres", "Item cuatro","Item cinco",
"Item seis","Item siete","Item ocho","Item nueve","Item diez"};
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//Referenciamos la lista a la actividad
lista = (ListView) findViewById(R.id.lista);
//creamos el arrayadapter
ArrayAdapter< String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1, datos);
//Vinculamos el adaptador a la lista
lista.setAdapter(adapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
}
主要佈局：
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.cursoandroid.miarrayadapter.MainActivity"
tools:ignore="MergeRootFrame"
>
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/lista"
/>
清單：
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.cursoandroid.miarrayadapter" >
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:theme="@style/AppTheme"
android:name=".MainActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
</FrameLayout>
我的字符串XML是：
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="app_name">MiarrayAdapter</string>
<string name="hello_world">Hello world!</string>
<string name="action_settings">Settings</string>
</resources>
謝謝。誰能說我，有什麼不對？

顯示你的logcat –
你能顯示你的strings.xml文件嗎？ – hakiko
是的，我編輯了我的文章。你可以現在就把它 –
