I have two EditText views whose height I wish to align. The problem is that I cannot predict which view will have more text and hence using android:layout_alignTop
and android:layout_alignBottom
will not work. The layout I am experimenting with is below. I have already tried android:layout_alignTop
and android:layoutAlignBottom
but they do not yield satisfactory results.
Layout 1
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText
android:id="@+id/text1"
android:layout_width="200dip"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:padding="5dip"
android:text="Text 1 bvhg hbjbj kjkbkj kjnjkn hlihj lklkkl"
/>
<EditText
android:id="@+id/text2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_toRightOf="@+id/text1"
android:padding="5dip"
android:text="Text 2 lasndklsa lkmsclslk klmsldmlk lksdl"
/>
</RelativeLayout>

But, if I were to change the text on the first EditText then some of the text in that box gets cut-off. See Layout 3 and Figure 3 below:

Is there a way to align the heights of EditText views when the amount of text in either view is not known ahead of time?
Well, I have to say, this is the first time I've ever found a TableLayout useful. Note the text LOOKS cut off in the preview (as it's really big), but when you compile and run, you'll see that the text is scrollable. The TableView does all the tricky stuff for you. I think this will work for you.
Just realised that you want the textviews to look the same size also - that's easy - give them a transparent background and make the background of the table have the background.
EDIT - One more thing - due to a framework bug, I had to use this:
android:inputType="none"
android:editable="false"
to get the text both scrollable and non-editable. Also, a good point from @mandel - use "fill_parent" not "match_parent" if programming for android devices of an api level less than 8.
<TableLayout
android:id="@+id/tableLayout1"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
xmlns:android="http://schemas.android.com/apk/res/android">
<TableRow
android:layout_height="fill_parent"
android:layout_width="wrap_content"
android:id="@+id/tableRow1"
android:gravity="center_vertical">
