Android Listview inside CoordinatorLayout how to make it scroll-able?

I have listactivity.java which has code like below. Note it uses
activity_main_listapps1.xml and listview_layout files.

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);


where activity_main_listapps1.xml is :

<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>


and listview_layout.xml is:

<?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>


This code is not scroll able. I tried adding android:layout_height to match_parent..something still missing.

Answer

remove your listview from appbar layout, and write it outside appbarlayout, also write it inside the nested scroll view inside the coordinate layout.

<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>
