See the layout xml:
<LinearLayout xmlns:tools="http://schemas.android.com/tools";
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
tools:context=".MainActivity" xmlns:android="
http://schemas.android.com/apk/res/android";>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="10dp"
android:layout_marginTop="10dp"
android:text="Temperature Chart"
android:textAppearance="?android:attr/textAppearanceLarge" />
<LinearLayout
android:id="@+id/chartContainer"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
<TextView
android:id="@+id/textTemperature"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:transformPivotX="0sp"
android:translationY="0sp"
android:rotation="-90"
android:text="Temperature" />
</LinearLayout>
</LinearLayout>
then I insert a chart view into the "chartContainer" LinearLayout. The
executing result is as the following picture:
you can see the problem is, after "textTemperature" is rotated, it still
occupy the room as before it rotated, bellow layout view confirmed this.

My question is how can I make the "textTemperature" widget only occupy the
width as it is looked like? that's, there is no additional blank between
"textTemperature" and the chart.
I know writing a customized widget or putting the rotated widget in an
individual FrameLayout could accomplish this, I mean to seek there is any
lighter way, such as a property, etc.
