如何使浏览指定的量互相重叠？ [英] How to make Views overlap each other by a specified amount?

问题描述

比方说，我想堆叠卡，我要穿上国王之上的女王，但仍然有国王的前20名左右的像素是可见的，所以你可以告诉它是女皇下。你怎么做到这一点？

我定义网格布局，线性布局容器。每个容器包含一个的ImageButton。最近我可以得到它侵占的ImageButton缩小占领下的ImageButton

就像这样：

我想堆叠imagebuttons，但仍然有潜在的imagebuttons仍然可以点击。

编辑：
我能够通过广泛的搜索，并在这里学习了很多关于意见看着办吧。
现在，我使用

  LinearLayout.LayoutParams LP =新LinearLayout.LayoutParams（LinearLayout.LayoutParams.WRAP_CONTENT，LinearLayout.LayoutParams.WRAP_CONTENT）;
lp.setMargins（0，0，0，-60）;
view.setLayoutParams（LP）;
 

解决方案

您可以设置的android：layout_marginBottom = - 50dp的顶视图，以重叠查看下方。在这里， 50dp 的是要重叠的意见数量。

这样的：

 ＆LT;的RelativeLayout的xmlns：机器人=htt​​p://schemas.android.com/apk/res/android
    的xmlns：工具=htt​​p://schemas.android.com/tool​​s
    机器人：layout_width =match_parent
    机器人：layout_height =match_parent＆GT;    ＆LT;的LinearLayout
        机器人：layout_width =WRAP_CONTENT
        机器人：layout_height =WRAP_CONTENT
        机器人：layout_centerHorizo​​ntal =真
        机器人：layout_centerVertical =真
        机器人：方向=垂直＆GT;        ＆LT;的ImageButton
            机器人：ID =@ + ID / imageButton1
            机器人：layout_width =100dp
            机器人：layout_height =100dp
            机器人：背景=＃FF0000
            机器人：layout_marginBottom = -  50dp/＆GT;        ＆LT;的ImageButton
            机器人：ID =@ + ID / imageButton2
            机器人：layout_width =100dp
            机器人：layout_height =100dp
            机器人：背景=＃00FF00
            机器人：layout_marginBottom = -  50dp/＆GT;        ＆LT;的ImageButton
            机器人：ID =@ + ID / imageButton3
            机器人：layout_width =100dp
            机器人：layout_height =100dp
            机器人：背景=＃0000FF/＆GT;    ＆LT; / LinearLayout中＆GT;＆LT; / RelativeLayout的＆GT;
 

通过code：

 的ImageButton imageButton1 =（的ImageButton）findViewById（R.id.imageButton1）;
        LinearLayout.LayoutParams的LayoutParams =（的LayoutParams）imageButton1
                .getLayoutParams（）;
        layoutParams.setMargins（layoutParams.leftMargin，
                layoutParams.topMargin，layoutParams.rightMargin，
                （layoutParams.bottomMargin  -  50））;
        imageButton1.setLayoutParams（的LayoutParams）;
 

Let's say I'm trying to stack cards, and I want to put a queen on top of a king, but still have the top 20 or so pixels of the king be visible so you can tell it's under the queen. How do you do this?

I've defined a grid layout, with linear layout containers. Each container contains one imagebutton. The closest I can get it is the encroaching imagebutton shrinks under the occupying imagebutton.

Like so: http://i.stack.imgur.com/broaD.png

I would like to stack the imagebuttons, but still have the underlying imagebuttons still be clickable.

Edit: I was able to figure it out by extensive searching here and learning a lot about views. I'm now using

LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(LinearLayout.LayoutParams.WRAP_CONTENT, LinearLayout.LayoutParams.WRAP_CONTENT);
lp.setMargins(0, 0, 0, -60);
view.setLayoutParams(lp); 

解决方案

You can set android:layout_marginBottom="-50dp" for the top view so as to overlap the view below it. Here, 50dp is the amount by which you want to overlap the views.

Like this:

<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" >

    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:orientation="vertical" >

        <ImageButton
            android:id="@+id/imageButton1"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:background="#ff0000"
            android:layout_marginBottom="-50dp" />

        <ImageButton
            android:id="@+id/imageButton2"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:background="#00ff00"
            android:layout_marginBottom="-50dp" />

        <ImageButton
            android:id="@+id/imageButton3"
            android:layout_width="100dp"
            android:layout_height="100dp"
            android:background="#0000ff" />

    </LinearLayout>

</RelativeLayout>

Through code:

ImageButton imageButton1 = (ImageButton) findViewById(R.id.imageButton1);
        LinearLayout.LayoutParams layoutParams = (LayoutParams) imageButton1
                .getLayoutParams();
        layoutParams.setMargins(layoutParams.leftMargin,
                layoutParams.topMargin, layoutParams.rightMargin,
                (layoutParams.bottomMargin - 50));
        imageButton1.setLayoutParams(layoutParams);
