Question

我需要像计算器键盘一样创建smth。 GridLayout非常适合它（仅适用于它:)）。所以，我使用支持库中的一个（compile 'com.android.support:gridlayout-v7:22.2.0'。这是我的xml：

<android.support.v7.widget.GridLayout
        android:layout_width="match_parent"
        android:layout_height="0dp"
        app:columnCount="4"
        app:rowCount="4"
        android:layout_gravity="bottom"
        android:layout_weight="4"
        app:alignmentMode="alignBounds"
        app:rowOrderPreserved="false"
        app:orientation="horizontal">

    <Button android:text="7"
            android:id="@+id/button7"
            app:layout_columnWeight="1"
            app:layout_rowWeight="1"
            style="@style/CalculatorButton"/>
    <Button android:text="8"

</android.support.v7.widget.GridLayout>

在Android 4.3-4.4上一切正常：

但Android 4.1-4.2存在问题：

所以，我无法理解我的坏处。

嗯，这是支持库中的错误。我用编译'com.android.support:gridlayout-v7:22.0.+'替换了编译'com.android.support:gridlayout-v7:22.2.0'，用代码制作了一些魔法，在4.1和4.3上检查过，现在它是工作！

Answer 2

我刚刚在我的项目中解决了这个问题。为所有按钮添加android:layout_width="0dp"和android:layout_height="0dp"可以解决问题。以下是我的布局中的部分：

<android.support.v7.widget.GridLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="fill"
    android:padding="16dp"
    app:columnCount="4"
    app:rowCount="5"
    app:orientation="horizontal">

    <Button
        android:text="Test"
        app:layout_gravity="fill"
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_columnWeight="1"
        app:layout_rowWeight="1"/>

    ...

</android.support.v7.widget.GridLayout>

Answer 3

compile 'com.android.support:design:22.2.0'

或尝试创建一个Adapter并通过该

将数据添加到GridView

Answer 4

你在LogCat上有任何错误吗？

如果您没有得到任何内容，请尝试导入gridlayout-v7

compile 'com.android.support:gridlayout-v7:19.0.0'

同时确保您已获得8 + minSdkVersion

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="18" />

您是否尝试将android.support.v7.widget.GridLayout替换为GridLayout？

来自支持库的GridLayout在API 16-17上无法正常工作
