Android ListView OnItemClickListener not working with unfocused PopupWindow

In my android app I have EditText

. When focus EditText

is displayed PopupWindow

, which contains ListView

. The user can continue to enter text EditText

when the screen is displayed PopupWindow

and at the same time he / she should be able to click on the item ListView

to reject PopupWindow

. (Depending on which element is ListView

clicked, PopupWindow

something else should happen besides the rejection , but that doesn't matter here.)

The problem is that while the "keep typing" part works, the "click" part doesn't work because it OnItemClickListener

ListView

never gets called and I can't figure out why.

Here's mine activity_main.xml

:

<RelativeLayout 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:background="#ddd"
    android:focusableInTouchMode="true"
    tools:context="com.example.popuptest3.MainActivity" >

    <EditText
        android:id="@+id/edtPhone"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="phone" />

</RelativeLayout>

      

My popup_window.xml

:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:background="#fff" >

    <ListView
        android:id="@+id/lstItems"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_marginBottom="60dp" />

    <Button
        android:id="@+id/btnDismiss"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:text="Dismiss" />

</RelativeLayout>

      

My list_item.xml

:

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="50dp" >

    <TextView
        android:id="@+id/txtItem"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:gravity="center_vertical"
        android:text="Item Text"
        android:textAppearance="?android:attr/textAppearanceMedium" />

</RelativeLayout>

      

In my class MainActivity

, I have the following preparation code:

private PopupWindow popup = null;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    prepareControls();
}

private void prepareControls() {
    final EditText edtPhone = (EditText)findViewById(R.id.edtPhone);
    edtPhone.setOnFocusChangeListener(new OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus)
                openPopup(edtPhone);
            else
                closePopup();
        }
    });
}

      

That is, I open PopupWindow

when it edtPhone

gains focus, and close PopupWindow

when it edtPhone

loses focus. Then I have:

private void openPopup(View parent) {
    closePopup();

    // Inflate the view of the PopupWindow.
    LayoutInflater layoutInflater = LayoutInflater.from(this);
    View view = layoutInflater.inflate(R.layout.popup_window,
            new LinearLayout(this), false);
    final Activity activity = this;

    // Prepare the ListView.
    ListView lstItems = (ListView)view.findViewById(R.id.lstItems);
    lstItems.setAdapter(new ListAdapter(this));
    lstItems.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view,
                int position, long id) {
            hideKeyboardAndClearFocus(activity);
        }
    });

    // Prepare the Button.
    Button btnDismiss = (Button)view.findViewById(R.id.btnDismiss);
    btnDismiss.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            hideKeyboardAndClearFocus(activity);
        }
    });

    // Create and show the PopupWindow.
    popup = new PopupWindow(view, 400, 300, false);
    popup.showAtLocation(parent, Gravity.LEFT | Gravity.TOP, 0, 60);
}

      

The button is btnDismiss

not part of my plan; I am adding it here for demonstration purposes only. Finally, I:

private void closePopup() {
    if (popup != null) {
        popup.dismiss();
        popup = null;
    }
}

private static void hideKeyboardAndClearFocus(Activity activity) {
    InputMethodManager manager = (InputMethodManager)activity.
            getSystemService(Activity.INPUT_METHOD_SERVICE);
    manager.hideSoftInputFromWindow(
            activity.getCurrentFocus().getWindowToken(), 0);
    activity.getWindow().getDecorView().clearFocus();
}

      

I think this is self-explanatory and the class ListAdapter

is pretty standard, so I omit it.

Now when I click edtPhone

it gets focus, the soft keyboard comes up and opens PopupWindow

. I can type something in edtPhone

, and when I click on btnDismiss

, it edtPhone

loses focus, the soft keyboard rejects and PopupWindow

closes as expected. But if instead btnDismiss

I click the element on lstItems

, nothing happens. Using Log

I can see what is OnItemClickListener

not being called. The funny thing is that ListView

you can scroll well, it just can't be clicked.

I know this post , but this solution doesn't work for my purpose. If I change this line:

popup = new PopupWindow(view, 400, 300, false);

      

to the next:

popup = new PopupWindow(view, 400, 300, true);

      

PopupWindow

becomes customizable and ListView

becomes clickable, okay, but then I can't keep typing in edtPhone

. In fact, if there are other activity controls, they all become inaccessible, as if it were PopupWindow

"modal".

I also tried android:focusable="false"

with no luck. And I am not doing autocomplete, so AutoCompleteTextView

not what I need.

So why is OnItemClickListener

n't it called for non-focusable ones PopupWindow

? Am I doing something wrong?

set popupwindow to non-focusable

popupwindow.setFocusable(false);
popupwindow.setTouchable(true);
popupwindow.setOutsideTouchable(true);

      

extend ListView and override following methods



@Override
public boolean hasFocus() {
    return true;
}

@Override
public boolean isFocused() {
    return true;
}

@Override
public boolean hasWindowFocus() {
    return true;
}

      

So AutoCompleteTextView implements popup for suggestions. If you need to select a list item using DPAD keys or other navigation keys, you need to pass key events from the EditText to the ListView.

I solved this problem by simply setting OnClickListener

to convertview

which is the parameter of the adapter method getView

. Then I call the onItemClick

listview onItemClickListener method .

No need to customize popupWindow . Infact, just using ListPopupWindow is easier as its only internally responsive method getView()

is that we add a few lines of code

ListPopupWindow popupWindow = new ListPopupWindow(mContext);

    MentionsAdapter adapter = new MentionsAdapter(mContext, suggestions);
    popupWindow.setOnItemClickListener(new android.widget.AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
            String username = mSuggestions.get(position);
            String mentionCompletion = username.substring(mCurrentQuery.length()).concat(" ");
            mEditor.getText().insert(mEditor.getSelectionEnd(), mentionCompletion);
            hideSuggestions();
        }
    });
   popupWindow.setAdapter(adapter);

      



MentionsAdapter

getView

method

@Override
    public View getView(int position, View convertView, ViewGroup parent) {
        if(convertView == null){
            convertView = LayoutInflater.from(context).inflate(,R.layout.item_user,parent,false);

        }
        // this is the key point of workaround
        convertView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               popupWindow.getListView().getOnItemClickListener()
                 .onItemClick(listView, v, position, getItemId(position));
            }
        });
        return convertView;
    }
