android - RelativeLayout with two textviews on one horizontal line with ellipsis support -

-

i trying setup relativelayout 2 textview shown on 1 line. first textview should aligned left. second textview should aligned right. if second textview text expand overlap first textview want ellipsize text in middle. don't want ellipsize first textview.

this have come with. problem second textview directly right of first textview instead of being aligned far right. seems cannot use alignparentright , torightof @ same time.

<relativelayout xmlns:android="http://schemas.android.com/apk/res/android"     xmlns:local="http://schemas.android.com/apk/res-auto"     android:layout_width="match_parent"     android:layout_height="match_parent">     <textview         android:id="@+id/left"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_alignparenttop="true"         android:layout_alignparentleft="true"         android:textappearance="?android:attr/textappearancemedium"         android:text="[detailedtype]"/>     <textview         android:id="@+id/right"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_torightof="@id/left"         android:layout_alignparenttop="true"         android:layout_alignparentright="true"         android:ellipsize="middle"         android:singleline="true"         android:textappearance="?android:attr/textappearancemedium"         android:text="[customername]"/> </relativelayout>

the basic idea achieve id add dummy invisible view in horizontal center of relativelayout , tell left textview to left of , right textview to right of it... see below

about problem aligning right, should stretch textview take half of screen , set android:gravity="right" on textview

<?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="match_parent">      <view         android:id="@+id/dummy"         android:layout_width="0dp"         android:layout_height="wrap_content"         android:layout_centerhorizontal="true"         />      <textview         android:id="@+id/left"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_alignparenttop="true"         android:layout_toleftof="@id/dummy"         android:text="[detailedtype]"         android:textappearance="?android:attr/textappearancemedium"/>       <textview         android:id="@+id/right"         android:layout_width="match_parent"         android:layout_height="wrap_content"         android:layout_alignparenttop="true"         android:layout_torightof="@id/left"         android:gravity="right"         android:ellipsize="middle"         android:singleline="true"         android:text="[customername]"         android:textappearance="?android:attr/textappearancemedium"/> </relativelayout>

but can use linerlayout job

<linearlayout     xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="match_parent"     android:layout_height="match_parent"     android:orientation="horizontal">       <textview         android:id="@+id/left"         android:layout_width="0dip"         android:layout_height="wrap_content"         android:layout_weight="1"         android:text="[detailedtype]"         android:textappearance="?android:attr/textappearancemedium"/>       <textview         android:id="@+id/right"         android:layout_width="0dip"         android:layout_height="wrap_content"         android:layout_weight="1"         android:ellipsize="middle"         android:singleline="true"         android:text="[customername]"         android:textappearance="?android:attr/textappearancemedium"/> </linearlayout>
