有什么方法可以将视图稍微置于其父布局之外? [英] Are there any ways to put view slightly outside its parent layout?

问题描述

这是有关Android布局的问题.这是我渴望想要得到的:

It's a question about Android layouts. Here's what I eagerly want to get:

深灰色是LinearLayout.橙色是布局X，然后绿色是FrameLayout.我需要将Green置于其父级-布局X之外.无法更改所描述的布局层次结构.唯一的选择是布局X-它可以是您想要的任何内容.

Dark-gray is a LinearLayout. Orange is layout X and then Green is a FrameLayout. I need to put Green outside its parent - layout X. The layout hierarchy described can't be changed. The only option is layout X - it could be whatever you want.

有什么想法吗?

推荐答案

您不能将Green部件放置在Layout X中，因为它不能在其父级外部绘制.

You can't put the Green part in Layout X, because it can not be drawn outside its parents.

因此，您应该实现RelativeLayout或FrameLayout(根布局)作为所有这些视图的父级.

So, you should implements a RelativeLayout or FrameLayout (root Layout) as the parents of all of these Views.

然后将绿色视图作为根布局的childView.

And Put the Green View as the childView of the root Layout.

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/layout_root"
    android:layout_width="fill_parent"
    android:layout_height="200dp"
    android:orientation="vertical" >

    <LinearLayout
        android:id="@+id/layout_dark_grey"
        android:layout_width="100dp"
        android:layout_height="match_parent"
        android:orientation="vertical" >
    </LinearLayout>

    <LinearLayout
        android:id="@+id/layout_orange"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_toRightOf="@id/layout_dark_grey"
        android:orientation="vertical" >
    </LinearLayout>

    <RelativeLayout
        android:id="@+id/layout_green"
        android:layout_width="100dp"
        android:layout_height="100dp"
        android:layout_centerVertical="true"
        android:layout_toLeftOf="300dp" >
    </RelativeLayout>

</RelativeLayout>
