Question

what I want to do in a view is have a textview and to the right of it, have another custom view X with the same height as the textview and have width=height:

+---------------------+---+
|A flexible string    | X |
+---------------------+---+

My attempt so far is:

Inside the X class:

@Override
protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec) {
    int height = getDefaultSize(getSuggestedMinimumHeight(), heightMeasureSpec);
    setMeasuredDimension(height,height);
    Log.v("measure","width:"+height + " height:"+height);
}

and my xml:

<RelativeLayout
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content">

    <TextView android:id="@+id/mytext"
     android:layout_width="wrap_content"
     android:layout_height="wrap_content"
     android:layout_alignParentLeft="true"/>

    <mystuff.X
     android:layout_width="wrap_content"
     android:layout_height="fill_parent"
     android:layout_toRightOf="@id/mytext"/>

</RelativeLayout>

The log statement prints out:

width:1073741823 height:1073741823
width:37 height:37
width:1073741823 height:1073741823
width:37 height:37
width:1073741823 height:1073741823
width:37 height:37

when the view is created and it fills the width of the screen:

+---------------------+-----------------+
|A flexible string    |      X          |
+---------------------+-----------------+

I would greatly appreciate any help with this.
Thanks!

You are treating the measure specs as actual pixels. They are in fact the ints that represent “fill_parent”, “wrap_content”, etc.

What you want to do is:

@Override
protected void onMeasure (int widthMeasureSpec, int heightMeasureSpec) {
    int height = getDefaultSize(getSuggestedMinimumHeight(), heightMeasureSpec);
    setMeasuredDimension(height,height);
    Log.v("measure","width:"+height + " height:"+height);
}
