Question

我正在尝试为我的 Android 应用程序创建一个布局，我想在其中显示图像，每个图像的宽度应为 50%，高度为 50%，到目前为止，我如何实现这一点，我构建了以下内容：

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"

    tools:context="test.com.tests.MainActivity"
    tools:showIn="@layout/app_bar_main">

    <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:stretchColumns="1">

        <TableRow>
            <!-- Column 1 -->
            <ImageButton
                android:id="@+id/tbl_txt1"
                android:layout_width="0dip"
                android:layout_height="wrap_content"
                android:layout_margin="4dip"
                android:layout_weight="1"
                android:background="@color/red"
                android:padding="10dip"
                android:text="Column 1"
                android:textColor="@color/white" />

            <!-- Column 2 -->
            <ImageButton
                android:id="@+id/tbl_txt2"
                android:layout_width="0dip"

                android:textColor="@color/white" />

        </TableRow>
    </TableLayout>

如果你只想使用 TableLayout，你可以使用类似的东西

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TableLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="@android:color/darker_gray">

        <TableRow android:layout_weight="1">

        </TableRow>

        <TableRow android:layout_weight="1">

        </TableRow>

    </TableLayout>

    <TableLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_weight="1"
        android:background="@android:color/darker_gray">

        <TableRow android:layout_weight="1">

        </TableRow>

        <TableRow android:layout_weight="1">

        </TableRow>

    </TableLayout>

</LinearLayout>

或者类似的东西

<?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">

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

        </LinearLayout>

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

        </LinearLayout>

    </LinearLayout>

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

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

        </LinearLayout>

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

        </LinearLayout>

    </LinearLayout>

</LinearLayout>
