Scrolling textview stops working

[Richard Hayward]

I have a TextView inside a ScrollView
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <ScrollView android:id="@+id/scrollView1" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_weight="1" android:scrollbars="vertical" android:fillViewport="true"> <TextView android:id="@+id/textview" android:layout_width="fill_parent" android:layout_height="fill_parent" android:freezesText="true"/> </ScrollView> <Button android:id="@+id/press" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Press Me" /> <Button android:id="@+id/clear" android:layout_width="fill_parent" android:layout_height="wrap_content" android:text="Clear" /> </LinearLayout>

Clicking the buttons either appends text to the TextView or sets its text to "".

private void setClickListeners() {
	((Button) findViewById(R.id.clear)).setOnClickListener(new OnClickListener() {
			public void onClick(View arg0) {
				textView.setText("");
	                }
	});
	((Button) findViewById(R.id.press)).setOnClickListener(new OnClickListener() {
			public void onClick(View arg0) {
				textView.append("Hello\n");
			}
	});
}

The odd thing is that the scrolling doesn't work until the device is rotated, after which it does, even if I start in portrait, rotate to landscape & then rotate back to portrait.

Set the text to "" and scrolling stops again.

Could anyone tell me what the cause is?
