I'm trying to write a list view on Android, but there's an error.

I'm going to write a list view Compilation works well

Your content must have a ListView whose id attribute is 'android.R.id.list' If you get this kind of error, it will explode if you execute it.

My source is

<ListView
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="0.8"></ListView>

m_Adapter = new ArrayAdapter(this, android.R.layout.simple_list_item_multiple_choice, new_name); listView = (ListView) findViewById(R.id.list);

 What's the problem?

I think the current activity is ListActivity. In case of ListActivity, The id of the list view should be as below.

 <ListView
        android:id="@android:id/list"
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="0.8"></ListView>

You have to register it like this. And listView = (ListView) findViewById(android.R.id.list); You have to fix this part like this, too.
