can't click on listview row with imagebutton

问题

I have trouble with listview. its items (rows) have imagebutton. imagebutton has \"android:onClick\" so this onclick event is working, but click on row doesnt work. if i remove imagebutton from row item, click on row works (listview has correct onclick listner). How can i fix it ? i need onclick event when user click on imagebutton and standart click event, when user select row (not click the imagebutton but click the row)

my listview:

<ListView xmlns:android=\"http://schemas.android.com/apk/res/android\"
        android:id=\"@+id/restaurants_list\"
        android:layout_width=\"fill_parent\"
        android:layout_height=\"fill_parent\"
        android:divider=\"@color/list_devider\"
        android:dividerHeight=\"1dp\"
        android:cacheColorHint=\"@color/list_background\" />

Unfortunately,

android:focusable="false"
android:focusableInTouchMode="false"

doesn't work for ImageButton.

I finally found the solution here. In your layout xml for those items, add

android:descendantFocusability="blocksDescendants" 

to the root view.

It works perfectly for a ListView that has ImageButtons. According to official reference, blocksDescendants means that the ViewGroup will block its descendants from receiving focus.

You can use a custom adapter for your listView (if you haven't already). And there, in the getView(int position, View inView, ViewGroup parent) method of the adapter do something like this:

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

    View v = inView;
    ViewHolder viewHolder; //Use a viewholder for sufficent use of the listview

    if (v == null) {
        LayoutInflater inflater = (LayoutInflater) adaptersContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        v = inflater.inflate(R.layout.list_item, null);
        viewHolder = new ViewHolder();
        viewHolder.image = (ImageView) v.findViewById(R.id.ImageView);
        v.setTag(viewHolder);
    } else {
        viewHolder = (ViewHolder) v.getTag();
    }

        .....

    viewHolder.image.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            //Click on imageView
        }i
    });

    v.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {

            //Click on listView row
        }
    });

        .....

    return (v);
}

See here if you need help creating your custom adapter.

If a row of listView have any clickable element like Button , Image..etc..then onItemClick will not work. So you need to write the click listener in getView of your list adapter.

回答4:

Set these properties for your button:

      android:focusable="false"
      android:focusableInTouchMode="false"

Or you can set it dynamically in your adapter class:

        yourButton.setFocusable(false);
    yourButton.setFocusableInTouchMode(false);

And make sure that you set the choice mode as single for the listview:

       listView.setChoiceMode(ListView.CHOICE_MODE_SINGLE);

In my case, android:descendantFocusability="blocksDescendants" for main layer did not work, neither in the ListView. I also tried android:focusable="false" android:focusableInTouchMode="false" which I heard that it is working for Buttons, but I had ImageButton so it didn't.

But setting the properties of the button in the CS file of the Layout worked.

var imageButton = view.FindViewById<ImageButton>(Resource.Id.imageButton1);
imageButton.Focusable = false;
imageButton.FocusableInTouchMode = false;
imageButton.Clickable = true;

If a row has multiple clickable elements, onItemClick() will not work. You will need to set the OnClickListener in the getView() method. Store the listeners the the View's tag so that they can be recycled, add methods to your listeners so they can be specialized for different rows.

        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
        View view = super.getView(position, convertView, parent);

        RowClickListeners listeners = (RowClickListeners) view.getTag();
        if (listeners == null) {
            listeners = new RowClickListeners();
        }

        // Row click listener:
        RowClickListener onClickListener = listeners.rowClickListener;
        if (onClickListener == null) {
            onClickListener = new RowClickListener();
            listeners.rowClickListener = onClickListener;
        }
                    onClickListener.setToPosition(pos);
        view.setOnClickListener(onClickListener);

        // Overflow listener:
        View btn = view.findViewById(R.id.ic_row_btn);
        ButtonListener btnListener = listeners.buttonClickListener;
        if (rowListener == null) {
            btnListener = new ButtonListener(activity);
            listeners.rowClickListener = btnListener;
        }
                    btnListener.setToPosition(pos);
        btnListener.setCollection(collectionId);
        btn.setOnClickListener(btnListener);
    }


    public static class RowClickListeners {
        public RowClickListener rowClickListener;
        public ButtonListener buttonClickListener;
    }

no single answer above worked for me, but a combination did.

I now set android:descendantFocusability="blocksDescendants" on the ListView and android:focusable="false" android:focusableInTouchMode="false" on the ImageButtons in the XML AND in Java I also set descendantFocusability(ViewGroup.FOCUS_BLOCK_DESCENDANTS) on the ListView and focusable(false), focusableInTouchMode(false), clickable(true) on the ImageButtons.
