如何让我的ListView在Android中填满整个屏幕？

Question

I'm making a listview in android, and my listview doesn't fill the entire screen. It has some remaining plain space below the listview (probably because i don't have enough items to fill the screen). I've searched for many solutions online, but none seem to be able to solve this problem.

Here is my layout:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="com.ListActivity">

 <ListView
     android:layout_width="match_parent"
     android:layout_height="match_parent"
     android:id = "@+id/customListview">

 </ListView>


</LinearLayout>

Here is my item_layout.xml:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id= "@+id/ItemNameSales"
        android:layout_alignParentLeft="true"
        android:text="Item Name"
        android:textAppearance="?android:attr/textAppearanceLarge"/>

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="match_parent"
        android:id= "@+id/ItemNameQty"
        android:layout_alignParentRight="true"
        android:text="Item Quantity"
        android:textAppearance="?android:attr/textAppearanceLarge"/>

</RelativeLayout>

Answer 1

你必须在dinamically改变它以适应intire屏幕！

list.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.MATCH_PARENT, CalculateHowYouNeedToFitScreen));

Answer 2

Your ListView is already fill entire screen problem is that you dont have have enaf items in list. Another thing that you shoud do is to create holder class to prevant ListView loose list order.You can change dinamicly widht and height of item to fill screen but that is bad practices in coding

   View itemView = convertView;
    ViewHolder holder;

    if (itemView == null) {

     itemView = getLayoutInflater().inflate(R.layout.YOURVIEW,parent,false);
     holder = new ViewHolder();
     itemView.setTag( holder );
    }else {
     holder = (ViewHolder) itemView.getTag();
    }
     SalesItemInformationLV iteminfo = item.get(position);

     holder.something = (TextView)itemView.findViewById(R.id.ItemNameSales);

     public class ViewHolder{

      public TextView something;
    }
