ListView row is not clickable after adding button to the row

Question

Currently, I have a ListView row. Clicking any area on the row, will yield ListView click events.

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.HONEYCOMB) {
        this.getListView().setChoiceMode(ListView.CHOICE_MODE_MULTIPLE_MODAL);
        this.getListView().setMultiChoiceModeListener(new ModeCallback());
        this.getListView().setOnItemClickListener(new ListViewOnItemClickListener());
    } else {
        // http://stackoverflow.com/questions/9754170/listview-selection-remains-persistent-after-exiting-choice-mode
        this.getListView().setOnItemLongClickListener(new ListViewOnItemLongClickListener());
        this.getListView().setOnItemClickListener(new ListViewOnItemClickListener());
    }

Now, for each row, I would like to add a small button. Clicking on the small button will yield button click event, which is different from ListView original click event.

In my ArrayAdapter, I use to have

public View getView(int position, View convertView, ViewGroup parent) {
    View rowView = convertView;

    if (rowView == null) {
        LayoutInflater inflater = activity.getLayoutInflater();
        rowView = inflater.inflate(R.layout.watchlist_row_layout, null);
        ...
    }

    Button button = (Button)rowView.findViewById(R.id.button1);
    button.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            Utils.showLongToast("BUTTON CLICK");
        }
    });

Clicking on the button will yield button click event. However, clicking on area other than button, will not yield any ListView click event anymore.

May I know why is it so? Is there any way to resolve this?

If you want to make both Rows and Buttons clickable, set

android:focusable="false"

for your Button. The same goes for ImageButtons, RadioButtons, ...

Android has been primarily designed for a large set of input methods. The entire system is completely capable of working with no touch screen. To navigate through the UI, the user can use a directional pad which focuses Views after Views if and only if those Views are focusable. By default, all Android controls are focusable. In order to prevent having controls that are not focus-reachable, the ListView will simply prevent the selection (and click) of an itemview. By design, the ListView blocks clicks of itemview containing at least one focusable descendant but it doesn’t make the content focus-reachable calling setItemsCanFocus(true).

Here is the whole great explaination: Having several clickable areas in a ListView
