ArrayAdpater IllegalStateException異常Android上

我使用arrayAdpater我listView，但我得到這個例外，我不明白爲什麼，我插入我的layout.xml的id和listView的ID當我初始化arrayAdpater，但我不知道要解決這個問題。ArrayAdpater IllegalStateException異常Android上

create_boundary_map.xml（在其上定義ListView的文件）

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="400px" 
    android:layout_height="match_parent" 
    android:layout_gravity="center" 
    android:orientation="vertical" > 

    <ListView 
     android:id="@+id/list_view" 
     android:layout_width="match_parent" 
     android:layout_height="138dp" > 
    </ListView> 

</LinearLayout>

功能我做這裏面：

ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, R.layout.create_boundary_map, R.id.list_view, 
       this.fooStrings());

我的logcat：

你可以發佈你的ArrayAdapter代碼嗎？ – 2014-09-01 16:51:27

Adapter需要一個具有TextView而不是ListView的佈局。您活動的onCreate內

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/item" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content"/>

然後使用您的佈局（create_boundary_map.xml）：

創建一個新的XML像list_item.xml

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.create_boundary_map); 
    // Use the adapter to populate your list: 
    ListView listView = (ListView) findViewById(R.id.list_view); 


    ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this, R.layout.list_item, R.id.item, this.fooStrings()); 

    listView.setAdapter(arrayAdapter); 
}

我可以如何整合我現有的XML？ – 2014-09-01 16:53:13

@YokupokuMaioku更新了一個完整的例子。 – Simas 2014-09-01 16:55:50

好，非常感謝。 – 2014-09-01 16:56:29

這是正確的方法來創建適配器：

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.create_boundary_map.xml); 
    //create_boundary_map.xml must contain list_view. 
    ListView myListView = (ListView) findViewById(R.id.list_view); 
ArrayAdapter<String> adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_1, this.fooStrings()); 
    myListView.setAdapter(adapter); 
... 
... 
... 
}

或者你可以創建自定義列布局，填補了值，例如：

row_layout.xml包含一個TextView稱爲myTextView

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
     <TextView 
      android:id="@+id/myTextView" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"/> 
</LinearLayout>

使用row_layout.xml

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.create_boundary_map.xml); 
     //create_boundary_map.xml must contain list_view. 
     ListView myListView = (ListView) findViewById(R.id.list_view); 
    ArrayAdapter<String> adapter = new ArrayAdapter(this, android.R.layout.row_layout, R.id.myTextView, this.fooStrings()); 
    myListView.setAdapter(adapter); 
    ... 
    ... 
    ... 
    }
