如何实现像这种图像布局的Android UI？ 关于android：clipChildren

Question

What I want to achieve is like this layout:

I have tried to use this code, to achieve like that image, but unfortunately, I failed. This is the snippet of my code:

 <RelativeLayout
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:layout_marginBottom="10dp"
        android:clipChildren="false"
        >



        <RelativeLayout
            android:id="@+id/text_area_third"
            android:layout_width="fill_parent"
            android:layout_height="wrap_content"
            android:background="@drawable/round_corner_background"
            android:focusable="false"
            android:paddingBottom="5dp"
            android:paddingLeft="5dp"
            android:paddingRight="5dp"
            android:paddingTop="5dp" >

            <TextView
                android:id="@+id/text_download_purch_third"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:layout_alignParentLeft="true"
                android:layout_alignRight="@+id/acron_icon"
                android:layout_marginLeft="5dp"
                android:layout_marginRight="30dp"
                android:layout_marginTop="10dp"
                android:gravity="left"
                android:maxLines="2"
                android:text="1asdasdasdasdadsasdasdadasdasdasdasdasdasdasdasd"
                android:textColor="@color/black"
                android:textSize="10sp"
                android:textStyle="normal" />

            <ImageView
                android:id="@+id/acron_icon"
                android:layout_width="20dp"
                android:layout_height="20dp"
                android:layout_alignParentRight="true"
                android:layout_centerVertical="true"
                android:layout_margin="5dp"
                android:layout_marginTop="10dp"
                android:background="@drawable/acron"
                android:scaleType="fitCenter" />
        </RelativeLayout>

         <LinearLayout
             android:layout_alignTop="@+id/text_area_third"
             android:layout_alignLeft="@+id/text_area_third"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:background="@color/orange"
             android:layout_marginLeft="-10dp"
             android:layout_marginTop="-10dp"
             android:padding="3dp" >

             <TextView
                 android:layout_width="wrap_content"
                 android:layout_height="wrap_content"
                 android:text="GET"
                 android:textColor="@color/white"
                 android:textSize="13sp"
                 android:textStyle="bold" />
         </LinearLayout>

    </RelativeLayout>

You can see that, the "GET" label(with orange background) is clipped through the parent bound. I have set the android:clipChildren="false" , but still it is clipped. Can somebody help me?

A single RelativeLayout is the way to go. Remember to keep things as simple as possible. In RelativeLayout the last declared elements are rendered on top of the others. The XML below should (kinda) fit your needs, just adjust images and margins and sizes as you require.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="180dp"
    android:layout_height="60dp"
    android:background="#DDD" >

    <TextView
        android:id="@+id/text_download_purch_third"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginBottom="3dp"
        android:layout_marginLeft="12dp"
        android:layout_marginRight="8dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/round_corner_background"
        android:maxLines="2"
        android:paddingLeft="4dp"
        android:paddingRight="25dp"
        android:paddingTop="16dp"
        android:text="1asdasdasdasdadsasdasdadasdasdasdasdasdasdasdasd"
        android:textColor="@color/black"
        android:textSize="10sp"
        android:textStyle="normal" />

    <ImageView
        android:id="@+id/acron_icon"
        android:layout_width="20dp"
        android:layout_height="20dp"
        android:layout_alignParentRight="true"
        android:layout_centerVertical="true"
        android:layout_margin="5dp"
        android:layout_marginTop="10dp"
        android:background="@drawable/acron"
        android:scaleType="fitCenter" />

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginLeft="8dp"
        android:layout_marginTop="4dp"
        android:background="#FFA0A0"
        android:padding="2dp"
        android:text="GET!"
        android:textColor="@color/white"
        android:textSize="13sp"
        android:textStyle="bold" />

</RelativeLayout>

Have you thought about using FrameLayout?? That makes the overlaying of image easier... (making one layout/view appear on top of another)... Here is a good tutorial...
