我尝试将我的所有项目集中在GridLayout中,我尝试了很多东西(使用RelativeLayout作为父级,然后使用layout_centerInParent,使用基本的android:layout_gravity =" center",尝试添加一些太空元素...)但我没有成功地按我的意愿集中我的项目。作为一个形象,他比言语更好,这就是我所拥有的:

这就是我想要的:

我目前的代码是:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/mainContainer"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="MainActivity">

    <LinearLayout
        android:orientation="vertical"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="#66000000">

        <TextView

        <RelativeLayout

            android:layout_weight="0.50"
            grid:columnCount="3"
            grid:orientation="horizontal">

            <SquareRelativeLayout

            <SquareRelativeLayout
                android:id="@+id/relativelayout2"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                grid:layout_columnWeight="1"
                grid:layout_gravity="fill"

                ...
            </SquareRelativeLayout>

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

        <include layout="@layout/draggable_linearlayout"/>

    </LinearLayout>

</RelativeLayout>

你有什么想法,我怎么能用GridLayout或类似的东西得到这样的结果?

Ps:SquareRelativeLayout只是一个简单的CustomLayout,它强制我的RelativeLayout为正方形(width = height)。

您需要GridLayout吗? 如果不是,你可以尝试这样的事情:

    <LinearLayout
        android:id="@+id/firstRow"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:weightSum="3">

        <RelativeLayout
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:background="@color/white"/>

        <RelativeLayout
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:background="@color/white"/>

        <RelativeLayout
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:background="@color/white"/>
    </LinearLayout>
    <LinearLayout
        android:id="@+id/SecondRow"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center"
        android:weightSum="3">

        <RelativeLayout
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:background="@color/white"/>

        <RelativeLayout
            android:layout_width="0dp"
            android:layout_height="50dp"
            android:layout_weight="1"
            android:background="@color/white"/>
    </LinearLayout>
