我想显示图像视图的一半屏幕和屏幕的其余部分我将显示多个这样的文本视图

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="?android:attr/listPreferredItemHeight"

     android:padding="6dip">

     <ImageView
        android:id="@+id/icon"

        android:layout_width="wrap_content"
        android:layout_height="fill_parent"

        android:layout_alignParentTop="true"
        android:layout_alignParentBottom="true"
        android:layout_marginRight="6dip"

        android:src="@drawable/icon" />

    <TextView  
        android:id="@+id/secondLine"

        android:layout_width="fill_parent"
        android:layout_height="26dip" 

        android:layout_toRightOf="@id/icon"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"

        android:singleLine="true"
        android:ellipsize="marquee"
        android:text="Simple application that shows how to use RelativeLayout" />

     <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"

        android:layout_toRightOf="@id/icon"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_above="@id/secondLine"
        android:layout_alignWithParentIfMissing="true"

        android:gravity="center_vertical"
        android:text="My Application" />

Answer 1

使用LinearLayout并使用weightsum属性，而不是相对布局。

样品，

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="?android:attr/listPreferredItemHeight"
    android:weightSum="2"
    android:orientation="horizontal">



    <ImageView
        android:id="@+id/icon"
        android:layout_width="0dip"
        android:layout_height="fill_parent"
        android:layout_alignParentBottom="true"
        android:layout_alignParentTop="true"
        android:layout_marginRight="6dip"
        android:layout_weight="1"
        android:src="@drawable/icon" />


    <LinearLayout android:layout_width="0dip"
        android:orientation="vertical"
        android:layout_height="fill_parent"
        android:layout_weight="1">

    <TextView
        android:id="@+id/secondLine"
        android:layout_width="fill_parent"
        android:layout_height="26dip"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_toRightOf="@id/icon"
        android:ellipsize="marquee"
        android:singleLine="true"
        android:text="Simple application that shows how to use RelativeLayout" />

    <TextView
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_above="@id/secondLine"
        android:layout_alignParentRight="true"
        android:layout_alignParentTop="true"
        android:layout_alignWithParentIfMissing="true"
        android:layout_toRightOf="@id/icon"
        android:gravity="center_vertical"
        android:text="My Application" />
</LinearLayout>
    </LinearLayout>

Answer 2

您需要使用权重概念

以下是代码：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:weightSum="10" >

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="5" >

    <ImageView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
    <!-- put your imagebackground image -->

</LinearLayout>

<LinearLayout
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:layout_weight="5"
    android:orientation="vertical" >

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="5"
        android:gravity="center"
        android:weightSum="1" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight=".33"
            android:text="firstText" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="5"
        android:gravity="center"
        android:weightSum="1" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight=".33"
            android:text="secondText" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_weight="5"
        android:gravity="center"
        android:weightSum="1" >

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_weight=".33"
            android:text="thirdText" />
    </LinearLayout>
</LinearLayout>

Answer 3

将所有屏幕分为两部分首先是imageview和其他布局采取所有其他视图并设置imageview权重和其他布局权重= 1并同时采取高度填充父级

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal" >

<ImageView
    android:id="@+id/info"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1"
    android:src="@drawable/ic_launcher"
    android:text="TextView" />

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1" >
</LinearLayout>

Answer 4

对父视图使用权重和，并为第一个子布局实现android:layout_weight="50"，为另一个子项实现相同的内容....

Answer 5

这对我有用：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="?android:attr/listPreferredItemHeight"
android:orientation="horizontal"
android:padding="6dip" >

<ImageView
    android:id="@+id/icon"
    android:layout_width="150dip"
    android:layout_height="fill_parent"
    android:layout_alignParentBottom="true"
    android:layout_alignParentTop="true"
    android:layout_marginRight="6dip"
    android:src="@drawable/icon" />

<LinearLayout 
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent">

<TextView
    android:id="@+id/secondLine"
    android:layout_width="fill_parent"
    android:layout_height="26dip"
    android:ellipsize="marquee"
    android:singleLine="true"
    android:text="Simple application that shows how to use RelativeLayout" />

<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:gravity="center_vertical"
    android:text="My Application" />

</LinearLayout>
