android - 如何用视图和布局填充 Android 屏幕？

使用以下内容：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" 
    android:background="#ffffff">

    <ImageView
    android:id="@+id/imageView1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="1"
    android:src="@drawable/ic_launcher" />

    <RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:layout_weight="1"
    android:background="#556677">
    </RelativeLayout>

    <Gallery
    android:id="@+id/gallery1"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:layout_weight="1" 
    android:background="#664411"/>

    <RelativeLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" 
    android:layout_weight="1"
    android:background="#997766">
    </RelativeLayout>
</LinearLayout>

使用线性布局作为您的父布局并赋予所有布局权重。

Answer 3

利用

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout     
android:layout_width="fill_parent"
android:layout_height="fill_parent"
orientation="vertical">
<ImageView
android:id="@+id/imageView1"
android:layout_width="wrap_content"
android:layout_height="0dp" 
android:layout_weight="1"
android:src="@drawable/ic_launcher" />

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp" 
android:layout_weight="1">
</RelativeLayout>

<Gallery
android:id="@+id/gallery1"
android:layout_width="match_parent"
android:layout_height="0dp" 
android:layout_weight="1"
/>

<RelativeLayout
android:layout_width="match_parent"
android:layout_height="0dp" 
android:layout_weight="1">
</RelativeLayout>

</LinearLayout>

使用线性布局并添加 android:layout:weight="1" 每个标签..如果你想使用相对布局，最好你应该得到屏幕尺寸并将它分成四个，如果你有四个视图
