ListView控件以弥补Android的整个屏幕 [英] ListView to cover entire screen in Android

问题描述

我在我的Andr​​oid应用程序（API 8）实施的列表视图。然而，该列表仅包括三个要素，因此，超过一半的屏幕的是空的。我想扩大列表视图覆盖了手机的整个屏幕。有哪些方法做同样的？

I have implemented a listview in my Android app (API 8). However, the list consists of only three elements and hence, more than half of the screen is empty. I want to expand the listview to cover the entire screen of the phone. What are some ways to do the same?

下面是我的布局XML文件：

Here is my layout XML file:

<?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="vertical" 
android:background="@color/white"
android:shape="rectangle"
android:paddingTop="5dp"
android:paddingBottom="0dp"
>


<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal" 
    android:weightSum="100"
    >

    <ImageView
        android:layout_weight="40"
        android:id="@+id/test_image"
        android:layout_width="158dp"
        android:layout_height="52dp"
        android:contentDescription="@string/footer"
        android:src="@drawable/logo1" />

    <Spinner
        android:id="@+id/spinner1"
        android:layout_width="127dp"
        android:layout_height="wrap_content"
        android:layout_gravity="right"
        android:layout_weight="60" 
        android:prompt="@string/city_prompt"
        />
</LinearLayout>

  <LinearLayout android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical"   
    >
    <ListView 
    android:id="@android:id/list"
    android:layout_weight="1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:background="#000000"
    android:drawSelectorOnTop="true"
    android:layout_gravity="center"
    android:dividerHeight="2dp"
    />


</LinearLayout>


</LinearLayout>

请注意，我想列表项，以覆盖整个屏幕，在地方只有三个项目。

Please note that I want the list items to cover the entire screen, with just three items in place.

推荐答案

我刚刚复制的XML，粘贴和尝试，并能正常工作。还有一件事要告诉的是，你不应该使用 layout_height =WRAP_CONTENT。相反，你可以把它作为的android：layout_height =0dip因为你已经使用的android：layout_weight =1这将使ListView的填补你的LinearLayout的剩余区域。

I just copied your XML, pasted and tried, and it works fine. One more thing to tell is that you should not use layout_height="wrap_content". Instead you can give it as android:layout_height="0dip" as you have already used android:layout_weight="1" which will make ListView fill the remaining area of your LinearLayout.
