如何自定义布局（高度和宽度）以及布局的容器？

I have created a TableLayout with two rows where first row has one TextView and second row has two columns, first one has a ListView and the second one has one EditText and a Button each in different rows. I want both rows of equal height (exactly half of the screen) and both of the columns of second row should be of equal width (exactly half of the screen). I Want to build something like this:

我应该如何进行？我应该选择哪种布局？

我认为您当前的解决方案不起作用（因为需要相等的空间（宽度和高度）+ListView在场）。一种解决方案是使用嵌套weights（这对性能不利，但是（可能在不知道你做什么的情况下）并不是那么重要的事情，会破坏你的应用程序）就像下面的布局一样：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <include
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        layout="@layout/identical_layout" />

    <TextView
        android:id="@+id/textView1"
        android:layout_width="fill_parent"
        android:layout_height="0dp"
        android:layout_weight="1"
        android:text="TextView" />

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

        <ListView
            android:id="@+id/list"
            android:layout_width="0dp"
            android:layout_height="fill_parent"
            android:layout_weight="1" >
        </ListView>

        <LinearLayout
            android:layout_width="0dp"
            android:layout_height="fill_parent"
            android:layout_weight="1"
            android:orientation="vertical" >

            <EditText
                android:layout_width="fill_parent"
                android:layout_height="wrap_content" />

            <Button
                android:layout_width="fill_parent"
                android:layout_height="wrap_content"
                android:text="ddd" />
        </LinearLayout>
    </LinearLayout>




</LinearLayout>

避免嵌套的另一种选择weights问题是使用一个RelativeLayout如下（我没有测试过）：

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent" >

    <include
        android:id="@+id/included_layout"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        layout="@layout/identical_layout" />

    <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:layout_below="@id/included_layout" >

        <View
            android:id="@+id/anchor"
            android:layout_width="0dp"
            android:layout_height="0dp"
            android:layout_centerVertical="true" />

        <TextView
            android:id="@+id/textView1"
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_above="@id/anchor"
            android:layout_alignParentTop="true"
            android:background="#99cc00"
            android:text="TextView" />

        <LinearLayout
            android:layout_width="fill_parent"
            android:layout_height="0dp"
            android:layout_alignParentBottom="true"
            android:layout_below="@id/anchor" >

            <ListView
                android:id="@+id/list"
                android:layout_width="0dp"
                android:layout_height="fill_parent"
                android:layout_weight="1" >
            </ListView>

            <LinearLayout
                android:layout_width="0dp"
                android:layout_height="fill_parent"
                android:layout_weight="1"
                android:orientation="vertical" >

                <EditText
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content" />

                <Button
                    android:layout_width="fill_parent"
                    android:layout_height="wrap_content"
                    android:text="ddd" />
            </LinearLayout>
        </LinearLayout>
    </RelativeLayout>

</RelativeLayout>
