How To Maintain The Position Of Listview

Possible Duplicate: Maintain/Save/Restore scroll position when returning to a ListView How can I maintain the position of my ListView in my activity when I go to another activit

Solution 1:

Declare global variables:

intindex = 0;
ListView list;

and make a reference to your ListView in onCreate():

list = (ListView) findViewById(R.id.my_list);

Next, in onResume(), add this line at the end:

list.setSelectionFromTop(index, 0);

Lastly, in onPause, add the following line to the end:

index = list.getFirstVisiblePosition();

Solution 2:

Do simple....

@OverrideprotectedvoidonPause()
{
   index = listView.getFirstVisiblePosition();
   // store index using shared preferences   
}

and..

@Override
public void onResume() {
super.onResume();
// get index from shared preferencesif(listView != null){
    if(listView.getCount() > index)
        listView.setSelectionFromTop(index, 0);
    else
        listView.setSelectionFromTop(0, 0);
}

Solution 3:

You should use onSaveInstanceState to store the scroll position and then use either onCreate or onRestoreInstanceState to restore it.

Solution 4:

Please note that using ListView.getScrollY() DOES NOT WORK WELL for restoring the scroll position.

See Android: ListView.getScrollY() - does it work?

It is referring to the scroll amount of the entire view, so it will almost always be 0.

It happened to me too most of the time that this value was 0. ListView.getFirstVisiblePosition() with ListView.setSelection() works more reliably.

Solution 5:

@OverrideprotectedvoidonPause()
{
    // Save scroll positionSharedPreferencespreferences= context.getSharedPreferences("SCROLL", 0);
    SharedPreferences.Editoreditor= preferences.edit();
    intscroll= mListView.getScrollY();
    editor.put("ScrollValue", scroll);
    editor.commit();
}

@OverrideprotectedvoidonResume()
{
    // Get the scroll positionSharedPreferencespreferences= context.getSharedPreferences("SCROLL", 0);
    intscroll= preferences.getInt("ScrollView", 0);
    mListView.scrollTo(0, scroll);
}
