试图让Android版的LinearLayout水平和垂直方向上拉伸 [英] Trying to get Android LinearLayout to stretch horizontally and vertically

问题描述

更新：我AP preciate建议使用GridView的，我相信这将提供更好的性能。然而，我在实现一个简单的GridView最初的努力导致了可耻的失败。我想搞清楚什么我做错了是另一个话题。为了解决这个问题的实现，我用OnWindowFocusChanged找到ANDROID_CONTENT高度，然后通过行设置行高数除以。这里的主要教训，是不是很多关于这个问题的讨论present是OnCreate中错误的地方设置的尺寸。 OnWindowFocusChanged时可以进行精确的测量后出现。这个信息是不是在这个话题很多很多的讨论经常提到的。

UPDATE: I appreciate the advice to use GridView, and I do believe that would provide better performance. However, my initial efforts at implementing a simple GridView have resulted in shameful failure. I suppose figuring out what I am doing wrong is for another topic. To fix this implementation, I used OnWindowFocusChanged to find ANDROID_CONTENT height, then divided by the number of rows to set row height. The major lesson here that is not present in many of the discussions on this issue is OnCreate is the WRONG place to set dimensions. OnWindowFocusChanged occurs later when accurate measurements can be made. This information is not mentioned often in the many, many discussions on this topic.

原文：
我工作的一个Android布局试图建立一个板三列四行。

ORIGINAL: I am working on an Android layout trying to set up a board with three columns and four rows.

我要拉伸板垂直和水平方向填满可用的屏幕。我试图通过行和列的重量=1选项嵌套的LinearLayout，但只能得到它的水平拉伸。

I want to stretch the board to fill the available screen both vertically and horizontally. I tried nesting LinearLayout by row and column with the weight="1" option, but could only get it to stretch horizontally.

在以下配置中，行拉伸以填充屏幕的宽度，但列设置为60dp。我曾尝试网格布局和TableLayout还，但一直没能得到期望的结果。

In the following configuration, the rows stretch to fill the width of the screen, but the columns are set at "60dp". I have tried GridLayout and TableLayout also, but haven't been able to get the desired result.

请给我建议。
        

please give me suggestion.

推荐答案

我不同意别人说你的必须的使用网格布局。尝试用LinearLayout中这种方法。我用网格的每个单元一般的景观，但任何控制会工作。

I disagree with others saying you must use a GridLayout. Try this approach with a LinearLayout. I used a generic View for each cell of the grid, but any control will work.

<?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" >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:orientation="horizontal" >

        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/red" />

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

        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/red" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:orientation="horizontal" >

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

        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/red" />

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

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:orientation="horizontal" >

        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/red" />

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

        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/red" />
    </LinearLayout>

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:orientation="horizontal" >

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

        <View
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1"
            android:background="@color/red" />

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

</LinearLayout>

此方法还需要在code中的布局没有手动操作，一切都在利用权重XML处理。

This approach also requires no manual manipulation of the layout in code, everything is handled in the xml using weights.
