android - 如何在xml中创建一半屏幕的imageview

Question

我想显示一半屏幕的 ImageView 和屏幕的其余部分我将像这样显示多个 TextView

<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" />

     </RelativeLayout>

你需要使用权重概念

下面是代码:

<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>
