它显示以下内容：

我希望使徽标从顶部占据屏幕的 1/4，其余信息应占屏幕的 3/4。但由于某种原因，它们都聚集在一起。我该如何解决？

我想做以下（粗略的草图）：

I am looking to make the logo take up 1/4 of the screen from top and the rest of the information should be 3/4 of the screen

You need to do the following. Remove the attribute android:weightSum from llBottom, set android:layout_weight to 1 in llPhone, set android:layout_weight to 3 in llPhoneInfo.

The total sume of the weights will be 4, llPhone will take up 1/4 of the screen and llPhoneInfo will take up 3/4 of the screen.

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/llBottom"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/llPhone"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:gravity="center"
        android:orientation="horizontal" >

        <ImageView ... />

    </LinearLayout>

    <LinearLayout
        android:id="@+id/llPhoneInfo"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="3"
        android:gravity="center"
        android:orientation="vertical"
        android:weightSum="6" >

        ...    

   </LinearLayout>

</LinearLayout>

Do a similar calculation for the other layouts.

You should also consider using a RelativeLayout instead of several nested LinearLayouts for better performance.

这里有很多代码重复。在我看来，您应该只有一个带有 ImageView 和 listView 的线性布局。对线性布局内的两个子视图和以编程方式使用布局权重。有很多很好的教程来设置自定义列表视图。这个涵盖了您需要的一切。安卓列表视图
