我创建了一个自定义线性布局,以使“方形”布局适合其父级的宽度,但我无法将其与另一个LinearLayout定位。
我希望LinearLayout
位于SquareLinearLayout
之下,我得到了这个(两个布局都是顶部对齐的):
我已经尝试过android:parentAlignBottom="true"
和android:gravity="bottom"
,但对我来说没有任何作用......
这是我的布局xml:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.dekajoo.rpg.MainActivity" >
<com.dekajoo.rpg.custom_layouts.SquareLinearLayout
android:id="@+id/game_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
android:orientation="vertical"
android:background="#f00" />
<android:LinearLayout
android:id="@+id/control_bar"
android:layout_width="match_parent"
android:layout_height="100dip"
android:background="#0f0"
android:gravity="center"
android:orientation="horizontal" />
</RelativeLayout>
这是我的SquareLinearLayout类:
package com.dekajoo.rpg.custom_layouts;
import android.content.Context;
import android.util.AttributeSet;
import android.widget.LinearLayout;
public class SquareLinearLayout extends LinearLayout {
public SquareLinearLayout(Context context) {
super(context);
}
public SquareLinearLayout(Context context, AttributeSet attrs) {
super(context, attrs);
}
/*public SquareView(Context context, AttributeSet attrs, int defStyle) {
super(context, attrs, defStyle);
}*/
@Override
public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
super.onMeasure(widthMeasureSpec, heightMeasureSpec);
int width = MeasureSpec.getSize(widthMeasureSpec);
int height = MeasureSpec.getSize(heightMeasureSpec);
int size = width > height ? height : width;
setMeasuredDimension(size, size);
}
}
谢谢,

将此添加到您的LinearLayout
,android:layout_below="@id/game_layout"
