layout布局奇怪现象

Question

中间这一大块的布局 是一个水平LinearLayout
有两个子 Relative width都是1
所有的layout_height 都是wrap_content
为什么 会有这么一块白色的？
具体代码<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"

布局Android

Answer 1

你指的白色是你选中的那部分么？？这整个布局都有问题，你的这个相对布局所有的都是从下往上排的，你一上来就指定了最下面的沉底了
            <TextView
                android:id="@+id/textView_share_popup_window_Renren"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="人人网"
                android:layout_alignLeft="@+id/button_share_popup_window_Renren"
                android:layout_alignParentBottom="true"
                android:layout_marginBottom="20dp" />                android:layout_alignParentBottom="true"
其他的都是在这个控件的上面，没有铺满的情况下自然就留出一片空白了

Answer 2

可是relative不是设为高度、、wrap content吗

Answer 3

可是relative不是设为高度、、wrap content吗

是包裹内容啊，可是你让它在父窗口的底部了                  android:layout_alignParentBottom="true"
其他的空间是从下往上排的，建议你把两个相对布局改成线性布局，把android:layout_alignParentBottom="true"这句话都去掉

谢谢了，问题最后是改relative的height为固定大小，就好了
