这是我得到的设计：

这是我想要的设计：

正如您所看到的，第二个线性布局落后于第一个线性布局，而不是相对布局的工作方式。第二个线性布局包含带有紫色背景的“Home Extension”文本。

Answer 1

RelativeLayout的不正常行为是因为android:elevation每当我们用任何视图声明这个属性时它会更改它的Z-Index以便视图出现在所有视图之上

为您的案例解决方案 1）从LinearLayout中删除android:elevation="@dimen/dp_10"

替换

<LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical"
      android:elevation="@dimen/dp_10">

带

 <LinearLayout
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:orientation="vertical">

OR 在视图中添加相同的高程，以便将其引入前面

 <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="20dp"
        android:elevation="@dimen/dp_10">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@color/colorPrimary"
            android:padding="@dimen/dp_5"
            android:text="@string/homeextension"
            android:textColor="@color/white" />
    </LinearLayout>

适用于RelativeLayout，FragmeLayout

的相同行为
