It is indeed happening because all the views are redrawn, so the edit text representing whatever row used to be focused is now a completely different object. Set a variable in your adapter: int currentlyFocusedRow;

in getView for your adapter: Add an onFocusChanged listener to each edit text and when that edit text gains focus, set currentlyFocusedRow = whatever row the focused edit text happens to be in. Also set any edit text that is in the currentlyFocusedRow to be focused.

blocks|key|420840|text|我也遇到了EditText失去焦点的问题，但是调用setDescendantFocusability(ListView.FOCUS_AFTER_DESCENDANTS)解决了这个问题。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|420841|@Override

I also had a problem of EditText loosing the focus, but calling <code>setDescendantFocusability(ListView.FOCUS_AFTER_DESCENDANTS)</code> solved it.

<pre><code>@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
 super.onViewCreated(view, savedInstanceState);
 final ListView lv = getListView();
 lv.setDescendantFocusability(ListView.FOCUS_AFTER_DESCENDANTS);
}

Example of implementing Sam Judd's suggestion with an additional switch use_last_focus

<pre><code>public class my_friends_adapter extends ArrayAdapter&lt;group_user&gt; {
 boolean use_last_focus=false;
 int currentlyFocusedRow=-1;
 String currentlyFocusedField="";

 public my_friends_adapter(Context context, int resource, ArrayList&lt;group_user&gt; users) {
 super(context, resource, users);
 }
 EditText tvName,tvEmail;

 @Override
 public View getView(int position, View convertView, ViewGroup parent) {

 if (convertView == null) convertView = LayoutInflater.from(getContext()).inflate(R.layout.my_friends_item, parent, false);
 tvName = (EditText) convertView.findViewById(R.id.tvName);
 tvEmail = (EditText) convertView.findViewById(R.id.tvEmail);
 if (use_last_focus &amp;&amp; currentlyFocusedRow ==position){
 if (currentlyFocusedField=="tvName")tvName.requestFocus();
 else tvEmail.requestFocus();
 use_last_focus=false;
 }
 tvName.setTag(position);//When focus is lost save the entered value for later use
 tvName.setOnFocusChangeListener(new View.OnFocusChangeListener() {
 @Override
 public void onFocusChange(View v, boolean hasFocus) {save_data2( v, hasFocus);
 }
 });

 tvEmail.setTag(position);//When focus is lost save the entered value for later use
 tvEmail.setOnFocusChangeListener(new View.OnFocusChangeListener() {
 @Override
 public void onFocusChange(View v, boolean hasFocus) {save_data2( v, hasFocus);}
 });

 return convertView;
 }


 public void save_data2(View v, boolean hasFocus){
 int position = (Integer) v.getTag();
 EditText tvName1 = (EditText) v.findViewById(R.id.tvName);
 EditText tvEmail1 = (EditText) v.findViewById(R.id.tvEmail);
 boolean data_changed=false;
 if (hasFocus) currentlyFocusedRow=position;
 if (!(tvName1==null)) {
 if (hasFocus) currentlyFocusedField="tvName";
 }

 if (hasFocus) currentlyFocusedField="tvEmail";
 }
 // set when data_changed
 // ..........
 if (!hasFocus &amp;&amp; data_changed) {
 //your code to save the changed data

 my_friends.adapter.notifyDataSetChanged();
 use_last_focus=true;

I have a few edittext within a listview. i have a generic focuslistener on the edittext that updates the value of the data model and also the background of the edittext when focus is lost by calling notifydatachanged . The problem is that if one of the edittext is holding focus, when i touch the next edittext, it gains focus momentarily then loses focus. I suspect it is due to the notifydatachanged method call that is causing all views to be redrawn, after which the focus is lost. Does anyone have a suggestion or work around on the issue? Thanks.

Android edittext in listview loses focus on calling notifydatachanged

我在listview中有几个edittext。我在edittext上有一个通用的focuslistener，它通过调用notifydatachanged来更新数据模型的值，以及当焦点丢失时edittext的背景。问题是，如果其中一个edittext保持焦点，当我触摸下一个edittext时，它会暂时获得焦点，然后失去焦...
