[android-developers] Re: Android widget layout doesn't change after rotation

The chart view was match_parent.

 

This problem happens due to the TextView which resides left to the chart view. From the layout picture I posted, we can see after rotaion, the TextView still occupy the room before it's rotated. So is there any way to make a widget to only occupy a necessary room after rotation?

 

Alternatively, it's also a good solution to make the text aligning in the manner like it's rotated. Is it possible?

Maybe make the chart view wider?

What did you set the width of the chart view to?  If it is wrap_content, I would at least try match_parent.

Thanks.

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.
