复杂的FrameLayout

FrameLayout 很简单，但不好用~

<?xml version="1.0" encoding="utf-8"?><merge xmlns:android="http://schemas.android.com/apk/res/android"    android:orientation="horizontal" android:layout_width="fill_parent" android:layout_height="45.0dip"     ><RelativeLayout     android:layout_width="fill_parent"    android:layout_height="wrap_content"    android:background="#87CEFF"    ><ImageView android:id="@+id/title_image" android:layout_width="wrap_content" android:layout_height="45.0dp"  android:src="@drawable/add_bookmark_button" android:background="#00000000"/><FrameLayout android:layout_width="fill_parent" android:layout_height="31.0dip" android:layout_marginLeft="6.0dip" android:layout_weight="1.0" android:layout_marginTop="7dp" android:layout_toRightOf="@id/title_image" > <LinearLayout android:padding="0.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:id="@+id/url_input_background"         android:visibility="visible"  android:layout_marginRight="5.0dip">    <ImageView  android:paddingLeft="3.0dip" android:layout_width="120.0dip"  android:layout_height="fill_parent" android:layout_marginLeft="14.0dip" android:layout_marginRight="100.0dip"       android:layout_weight="1.0" android:layout_alignParentLeft="true" android:background="#F5FFFA" /> </LinearLayout>   <LinearLayout android:layout_gravity="center_vertical|center_horizontal" android:orientation="horizontal" android:id="@+id/url_input"     android:padding="0.0dip" android:visibility="visible" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_marginRight="5.0dip"> <AutoCompleteTextView  android:textSize="16.0dip" android:id="@+id/url_et" android:background="#00ffffff" android:paddingLeft="3.0dip" android:layout_width="150.0dip"     android:layout_height="fill_parent" android:layout_marginLeft="14.0dip" android:layout_marginRight="31.0dip" android:singleLine="true" android:completionThreshold="1"     android:layout_weight="1.0" android:layout_alignParentLeft="true" android:dropDownWidth="fill_parent" android:dropDownHeight="fill_parent" android:dropDownVerticalOffset="6.0dip"/>    </LinearLayout>             <FrameLayout android:layout_gravity="center_vertical|center_horizontal" android:orientation="horizontal" android:padding="0.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_marginRight="0.0dip">         <LinearLayout android:padding="0.0dip" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="horizontal" android:id="@+id/url_input_background"         android:visibility="visible"  android:layout_marginRight="5.0dip">      <ImageView  android:paddingLeft="3.0dip" android:layout_width="250.0dip"  android:layout_height="fill_parent" android:layout_marginLeft="185.0dip" android:layout_marginRight="40.0dip"       android:layout_weight="1.0"  android:background="#F5FFFA" />    </LinearLayout>   <LinearLayout android:layout_gravity="center_vertical|center_horizontal" android:orientation="horizontal" android:id="@+id/url_input"     android:padding="0.0dip" android:visibility="visible" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_marginRight="5.0dip">   <AutoCompleteTextView  android:textSize="16.0dip" android:id="@+id/url_et_2" android:background="#00ffffff" android:paddingLeft="3.0dip" android:layout_width="30.0dip"     android:layout_height="fill_parent" android:layout_marginLeft="185.0dip" android:layout_marginRight="0.0dip" android:singleLine="true" android:completionThreshold="1"     android:layout_weight="1.0" android:layout_alignParentLeft="true" android:dropDownWidth="fill_parent" android:dropDownHeight="fill_parent" android:dropDownVerticalOffset="6.0dip"/></LinearLayout></FrameLayout></FrameLayout> </RelativeLayout></merge>
