Focusable EditText inside ListView

I've spent about 6 hours on this so far, and been hitting nothing but roadblocks. The general premise is that there is some row in a ListView (whether it's generated by the adapter, or added as a header view) that contains an EditText widget and a Button. All I want to do is be able to use the jogball/arrows, to navigate the selector to individual items like normal, but when I get to a particular row -- even if I have to explicitly identify the row -- that has a focusable child, I want that child to take focus instead of indicating the position with the selector.

I've tried many possibilities, and have so far had no luck.

layout:

<ListView
    android:id="@android:id/list" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent"
    />

Header view:

EditText view = new EditText(this);
listView.addHeaderView(view, null, true);

Assuming there are other items in the adapter, using the arrow keys will move the selection up/down in the list, as expected; but when getting to the header row, it is also displayed with the selector, and no way to focus into the EditText using the jogball. Note: tapping on the EditText will focus it at that point, however that relies on a touchscreen, which should not be a requirement.

ListView apparently has two modes in this regard:

1. setItemsCanFocus(true): selector is never displayed, but the EditText can get focus when using the arrows. Focus search algorithm is hard to predict, and no visual feedback (on any rows: having focusable children or not) on which item is selected, both of which can give the user an unexpected experience.
2. setItemsCanFocus(false): selector is always drawn in non-touch-mode, and EditText can never get focus -- even if you tap on it.

To make matters worse, calling editTextView.requestFocus() returns true, but in fact does not give the EditText focus.

What I'm envisioning is basically a hybrid of 1 & 2, where rather than the list setting if all items are focusable or not, I want to set focusability for a single item in the list, so that the selector seamlessly transitions from selecting the entire row for non-focusable items, and traversing the focus tree for items that contain focusable children.

Any takers?

This helped me.
In your manifest :

<activity android:name= ".yourActivity" android:windowSoftInputMode="adjustPan"/>

Sorry, answered my own question. It may not be the most correct or most elegant solution, but it works for me, and gives a pretty solid user experience. I looked into the code for ListView to see why the two behaviors are so different, and came across this from ListView.java:

    public void setItemsCanFocus(boolean itemsCanFocus) {
        mItemsCanFocus = itemsCanFocus;
        if (!itemsCanFocus) {
            setDescendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS);
        }
    }

So, when calling setItemsCanFocus(false), it's also setting descendant focusability such that no child can get focus. This explains why I couldn't just toggle mItemsCanFocus in the ListView's OnItemSelectedListener -- because the ListView was then blocking focus to all children.

What I have now:

<ListView
    android:id="@android:id/list" 
    android:layout_height="match_parent" 
    android:layout_width="match_parent"
    android:descendantFocusability="beforeDescendants"
    />

I use beforeDescendants because the selector will only be drawn when the ListView itself (not a child) has focus, so the default behavior needs to be that the ListView takes focus first and draws selectors.

Then in the OnItemSelectedListener, since I know which header view I want to override the selector (would take more work to dynamically determine if any given position contains a focusable view), I can change descendant focusability, and set focus on the EditText. And when I navigate out of that header, change it back it again.

public void onItemSelected(AdapterView<?> listView, View view, int position, long id)
{
	if (position == 1)
	{
		// listView.setItemsCanFocus(true);

		// Use afterDescendants, because I don't want the ListView to steal focus
		listView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
		myEditText.requestFocus();
	}
	else
	{
		if (!listView.isFocused())
		{
			// listView.setItemsCanFocus(false);

			// Use beforeDescendants so that the EditText doesn't re-take focus
			listView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
			listView.requestFocus();
		}
	}
}

public void onNothingSelected(AdapterView<?> listView)
{
	// This happens when you start scrolling, so we need to prevent it from staying
	// in the afterDescendants mode if the EditText was focused 
	listView.setDescendantFocusability(ViewGroup.FOCUS_BEFORE_DESCENDANTS);
}

Note the commented-out setItemsCanFocus calls. With those calls, I got the correct behavior, but setItemsCanFocus(false) caused focus to jump from the EditText, to another widget outside of the ListView, back to the ListView and displayed the selector on the next selected item, and that jumping focus was distracting. Removing the ItemsCanFocus change, and just toggling descendant focusability got me the desired behavior. All items draw the selector as normal, but when getting to the row with the EditText, it focused on the text field instead. Then when continuing out of that EditText, it started drawing the selector again.

My task was to implement ListView which expands when clicked. The additional space shows EditText where you can input some text. App should be functional on 2.2+ (up to 4.2.2 at time of writing this)

I tried numerous solutions from this post and others I could find; tested them on 2.2 up to 4.2.2 devices. None of solutions was satisfactionary on all devices 2.2+, each solution presented with different problems.

I wanted to share my final solution :

1. set listview to android:descendantFocusability="afterDescendants"
2. set listview to setItemsCanFocus(true);
3. set your activity to android:windowSoftInputMode="adjustResize" Many people suggest adjustPan but adjustResize gives much better ux imho, just test this in your case. With adjustPan you will get bottom listitems obscured for instance. Docs suggest that ("This is generally less desirable than resizing"). Also on 4.0.4 after user starts typing on soft keyboard the screen pans to the top.
4. on 4.2.2 with adjustResize there are some problems with EditText focus. The solution is to apply rjrjr solution from this thread. It looks scarry but it is not. And it works. Just try it.

Additional 5. Due to adapter being refreshed (because of view resize) when EditText gains focus on pre HoneyComb versions I found an issue with reversed views: https://stackoverflow.com/questions/15783089/getting-view-for-listview-item-reverse-order-on-2-2-works-on-4-0-3

If you are doing some animations you might want to change behaviour to adjustPan for pre-honeycomb versions so that resize doesnt fire and adapter doesn't refresh the views. You just need to add something like this

if(android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.HONEYCOMB)
		getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN);
	

All this gives acceptable ux on 2.2 - 4.2.2 devices. Hope it will save people some time as it took me at least several hours to come to this conclusion.

This saved my life--->

1. set this line

   ListView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);

2. Then in your manifest in activity tag type this-->

   <activity android:windowSoftInputMode="adjustPan">

Your usual intent

We're trying this on a short list that does not do any view recycling. So far so good.

XML:

<RitalinLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    >
  <ListView
      android:id="@+id/cart_list"
      android:layout_width="match_parent"
      android:layout_height="match_parent"
      android:scrollbarStyle="outsideOverlay"
      />
</RitalinLayout>

Java:

/**
 * It helps you keep focused.
 *
 * For use as a parent of {@link android.widget.ListView}s that need to use EditText
 * children for inline editing.
 */
public class RitalinLayout extends FrameLayout {
  View sticky;

  public RitalinLayout(Context context, AttributeSet attrs) {
    super(context, attrs);

    ViewTreeObserver vto = getViewTreeObserver();

    vto.addOnGlobalFocusChangeListener(new ViewTreeObserver.OnGlobalFocusChangeListener() {
      @Override public void onGlobalFocusChanged(View oldFocus, View newFocus) {
        if (newFocus == null) return;

        View baby = getChildAt(0);

        if (newFocus != baby) {
          ViewParent parent = newFocus.getParent();
          while (parent != null && parent != parent.getParent()) {
            if (parent == baby) {
              sticky = newFocus;
              break;
            }
            parent = parent.getParent();
          }
        }
      }
    });

    vto.addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
      @Override public void onGlobalLayout() {
        if (sticky != null) {
          sticky.requestFocus();
        }
      }
    });
  }
}

this post was matching exactly my keywords. I have a ListView header with a search EditText and a search Button.

In order to give focus to the EditText after loosing the initial focus the only HACK that i found is:

	searchText.setOnClickListener(new View.OnClickListener() {
		@Override
		public void onClick(View arg0) {
			// LOTS OF HACKS TO MAKE THIS WORK.. UFF...
			searchButton.requestFocusFromTouch();
			searchText.requestFocus();
		}
	});

Lost lots of hours and it's not a real fix. Hope it helps someone tough.

If the list is dynamic and contains focusable widgets, then the right option is to use RecyclerView instead of ListView IMO.

The workarounds that set adjustPan, FOCUS_AFTER_DESCENDANTS, or manually remember focused position, are indeed just workarounds. They have corner cases (scrolling + soft keyboard issues, caret changing position in EditText). They don't change the fact that ListView creates/destroys views en masse during notifyDataSetChanged.

With RecyclerView, you notify about individual inserts, updates, and deletes. The focused view is not being recreated so no issues with form controls losing focus. As an added bonus, RecyclerView animates the list item insertions and removals.

Here's an example from official docs on how to get started with RecyclerView: Developer guide - Create a List with RecyclerView

some times when you use android:windowSoftInputMode="stateAlwaysHidden"in manifest activity or xml, that time it will lose keyboard focus. So first check for that property in your xml and manifest,if it is there just remove it. After add these option to manifest file in side activity android:windowSoftInputMode="adjustPan"and add this property to listview in xml android:descendantFocusability="beforeDescendants"

Another simple solution is to define your onClickListener, in the getView(..) method, of your ListAdapter.

public View getView(final int position, View convertView, ViewGroup parent){
    //initialise your view
    ...
    View row = context.getLayoutInflater().inflate(R.layout.list_item, null);
    ...

    //define your listener on inner items

    //define your global listener
    row.setOnClickListener(new OnClickListener(){
		public void onClick(View v) {
			doSomethingWithViewAndPosition(v,position);
		}
	});
	
	return row;

That way your row are clickable, and your inner view too :)

The most important part is to get the focus working for the list cell. Especially for list on Google TV this is essential:

setItemsCanFocus method of the list view does the trick:

...
mPuzzleList = (ListView) mGameprogressView.findViewById(R.id.gameprogress_puzzlelist);
mPuzzleList.setItemsCanFocus(true);
mPuzzleList.setAdapter(new PuzzleListAdapter(ctx,PuzzleGenerator.getPuzzles(ctx, getResources(), version_lite)));
...

My list cell xml starts like follows:

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
             android:id="@+id/puzzleDetailFrame"
             android:focusable="true"
			 android:nextFocusLeft="@+id/gameprogress_lessDetails"
			 android:nextFocusRight="@+id/gameprogress_reset"
...

nextFocusLeft/Right are also important for D-Pad navigation.

For more details check out the great other answers.

I just found another solution. I believe it's more a hack than a solution but it works on android 2.3.7 and android 4.3 (I've even tested that good old D-pad)

init your webview as usual and add this: (thanks Michael Bierman)

listView.setItemsCanFocus(true);

During the getView call:

editText.setOnFocusChangeListener(
    new OnFocusChangeListener(View view,boolean hasFocus){
        view.post(new Runnable() {
            @Override
            public void run() {
                view.requestFocus();
                view.requestFocusFromTouch();
            }
     });

Just try this

android:windowSoftInputMode="adjustNothing"

in the

> activity

section of your manifest. Yes, it adjusts nothings, which means the editText will stay where it is when IME is opening. But that's just an little inconvenience that still completely solves the problem of losing focus.

In my case, there is 14 input edit text in the list view. The problem I was facing, when the keyboard open, edit text focus lost, scroll the layout, and as soon as focused view not visible to the user keyboard down. It was not good for the user experience. I can't use windowSoftInputMethod="adjustPan". So after so much searching, I found a link that inflates custom layout and sets data on view as an adapter by using LinearLayout and scrollView and work well for my case.
