I needed a TextView to take the rest of the screen realstate. This TextView would behave as a logging component.
I tried using android:singleLine=”false” but that didn’t cut it.
What I did:
Add a ScrollView (with android:fillViewport=”true” and android:layout_weight=”1″), then add a LinearLayout (yup…), and then add the TextView to fill all of that up (android:layout_weight=”1″ too)
Here’s the only thing that worked for me:
<ScrollView android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_weight="1" android:fillViewport="true">
<LinearLayout android:layout_width="fill_parent" android:layout_height="fill_parent">
<TextView android:text="@+id/TextView01"
android:id="@+id/logTextView"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:textColor="#000"
android:background="#fff"
android:layout_weight="1"></TextView>
</LinearLayout>
</ScrollView>
Then on your Activity, do this:
_logTextView = (TextView) findViewById(R.id.logTextView);
_logTextView.setText("");
//and here comes the magic
_logTextView.setMovementMethod(ScrollingMovementMethod.getInstance());
