我想有例如LinearLayout或者RelativeLayout从屏幕的,而不是一个孤独的左侧滑动ListView.

我试图将使用LinearLayout与android:layout_gravity="start"和我在运行时有此错误:

ClassCastException: android.widget.LinearLayout$LayoutParams cannot 
be cast to android.support.v4.widget.DrawerLayout$LayoutParams

这是布局文件:

<android.support.v4.widget.DrawerLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/drawer_layout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="@android:color/white"
    >

    <FrameLayout
        android:id="@+id/content_frame"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <LinearLayout 
        android:layout_width="320dp"
        android:layout_height="match_parent"
        android:layout_gravity="start"
        android:orientation="vertical">

        <ImageView 
            android:id="@+id/ivwLogo"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:src="@drawable/video_icon"
        />

        <ListView 
            android:id="@+id/left_drawer"
            android:layout_width="320dp"
            android:layout_height="match_parent"
            android:choiceMode="singleChoice"
            android:divider="@android:color/transparent"
            android:dividerHeight="0dp"
            android:background="@android:color/white"
        />

    </LinearLayout>
</android.support.v4.widget.DrawerLayout>

谢谢

我的目标很简单.我想添加一个"红矩形"作为headerview到ListView.所以我创建了一个简单的活动

public class MainActivity extends Activity {
    private String[] adapterData = new String[] { "Afghanistan", "Albania", "Algeria", 
            "American Samoa", "Andorra", "Angola"}; 

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ListView lv;
        lv = (ListView)findViewById(R.id.list);

        LayoutInflater lf;
        View headerView;
        lf = this.getLayoutInflater();
        headerView = (View)lf.inflate(R.layout.header, null, false);

        lv.addHeaderView(headerView, null, false);

        lv.setAdapter(new ArrayAdapter<String>(this, R.layout.list_item, adapterData)); 
    }
}

activity_main.xml中

<ListView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/list"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#FF0" 
        android:cacheColorHint="#0000"
        android:paddingLeft="20dip"
        android:paddingRight="20dip"
        android:divider="#0000"
        android:scrollbarStyle="outsideOverlay" />

list_item.xml

<TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@android:id/text1"
    android:layout_width="match_parent"
    android:layout_height="0dip"
    android:minHeight="40dip"
    android:singleLine="true" …
