Inflate rows dynamically but strange behavior when the orientation of the device is changed

Question

I'm trying to inflate my rows dynamically but when I change the orientation of the tablet, I get everything unselected and the checkbox name is filled with the information of the last row. For example, supose I have two checkboxes (two rows) the first one says "hello" and the second says "good bye". If I rotate the tablet I get the first and second checkbox with the name "good bye" and everything unselected.

<ScrollView 
    android:layout_width="match_parent"
    android:layout_height="match_parent">


            <TableLayout
                android:id="@+id/tableLayoutList"
                android:layout_width="match_parent"
                android:layout_height="wrap_content" /> 

</ScrollView>

I have my row defined like this (mRowLayout.xml):

<TableRow xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/LinearLayoutRow"
android:layout_width="match_parent"
android:layout_height="match_parent">

    <CheckBox
        android:id="@+id/checkBoxServEmail"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />
</TableRow>

And then I use the following code to inflate my row:

private void fillTable(View v, Cursor c) {

TableLayout ll = (TableLayout) v.findViewById(R.id.tableLayoutList);

View mTableRow = null;
int i = 0;
while(!c.isAfterLast()){
    i++;
    mTableRow = (TableRow) View.inflate(getActivity(), R.layout.mRowLayout, null);

     CheckBox cb = (CheckBox)mTableRow.findViewById(R.id.checkBoxServEmail);

             Log.e("debugging", "email: "+c.getString(c.getColumnIndex(Serv.EMAIL)));
     cb.setText( c.getString(c.getColumnIndex(Serv.EMAIL)));


     mTableRow.setTag(i);

    //add TableRows to TableLayout
    ll.addView(mTableRow);

    c.moveToNext();
}
}

Does anyone knows why do I have this strange behavior?. Also notice that I put a Log.e for print in my log cat whats going on. And I get "hello" and "good bye" every time I change the orientation of my device, but the setText doesnt seem to work properly.

Please help, I have been with this issue for hours and I don't get it :(

Answer 1

The activity is destroyed and recreated when you change device orientation. You should use the

onSaveInstanceState

callback to save your current UI data. And use onCreate to restore it:

if (savedInstanceState == null) {

    // first run

} else {

    // not first run

}
