Android的ListView里面CoordinatorLayout如何使它可以滚动？

Question

我有listactivity.java它有像下面的代码。注意它使用 activity_main_listapps1.xml和listview_layout文件。

setContentView(R.layout.activity_main_listapps1); 

String[] from = { "flag","label","cur" ,"right_flag"}; 

    // Ids of views in listview_layout 
    int[] to = { R.id.flag,R.id.txt,R.id.cur,R.id.right_flag}; 

    // Instantiating an adapter to store each items 
    // R.layout.listview_layout defines the layout of each item 
    SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), aList, R.layout.listview_layout, from, to); 

    // Getting a reference to listview of layout file 
    ListView listView = (ListView) findViewById(R.id.listview); 

    // Setting the adapter to the listView 
    listView.setAdapter(adapter); 

其中activity_main_listapps1.xml是：

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:app="http://schemas.android.com/apk/res-auto" 
    android:id="@+id/drawer_design_support_layout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    <android.support.design.widget.CoordinatorLayout 
     android:id="@+id/rootLayout" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 
     <android.support.design.widget.AppBarLayout 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content"> 
      <android.support.design.widget.TabLayout 
       android:id="@+id/tab_layout" 
       android:layout_width="match_parent" 
       android:layout_height="wrap_content" 
       app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" /> 
      <ListView 
       android:id="@+id/listview" 
       android:layout_width="fill_parent" 
       android:layout_height="wrap_content" 
       /> 
     </android.support.design.widget.AppBarLayout> 
    </android.support.design.widget.CoordinatorLayout> 
</android.support.v4.widget.DrawerLayout> 

和listview_layout.xml是：

<?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" 
    android:orientation="horizontal" 
    > 
    <ImageView 
     android:id="@+id/flag" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:contentDescription="hello" 
     android:paddingTop="10dp" 
     android:paddingRight="10dp" 
     android:paddingBottom="10dp" 
     android:layout_weight="1" /> 

    <LinearLayout 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:orientation="vertical" 
     android:layout_weight="2"> 
     <TextView 
      android:id="@+id/txt" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textSize="15dp" 
      /> 

     <TextView 
      android:id="@+id/cur" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:textSize="10dp" 
      /> 
    </LinearLayout> 


    <ImageView 
     android:id="@+id/right_flag" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:contentDescription="hello" 
     android:paddingTop="10dp" 
     android:paddingRight="10dp" 
     android:paddingBottom="10dp" 
     android:visibility="visible" 
     android:layout_weight="1" /> 
</LinearLayout> 

这个代码不滚动能。我试着将android：layout_height添加到match_parent..something仍然丢失。

从appbar布局中删除你的列表视图，并将其写在appbarlayout之外，并将其写入坐标布局内的嵌套滚动视图内。

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:id="@+id/drawer_design_support_layout" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 
<android.support.design.widget.CoordinatorLayout 
    android:id="@+id/rootLayout" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 
    <android.support.design.widget.AppBarLayout 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content"> 
     <android.support.design.widget.TabLayout 
      android:id="@+id/tab_layout" 
      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      app:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar" /> 
     <ListView 
      android:id="@+id/listview" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      /> 
    </android.support.design.widget.AppBarLayout> 
      <android.support.v4.widget.NestedScrollView 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    app:layout_behavior="@string/appbar_scrolling_view_behavior" 
    android:fillViewport="true"> 
      <ListView 
      android:id="@+id/listview" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      app:layout_behavior="@string/appbar_scrolling_view_behavior"/> 
     <android.support.v4.widget.NestedScrollView/> 
</android.support.design.widget.CoordinatorLayout>
