ListView

Answer 1

Probably you've found how to do it, but you can call

ListView.setItemsCanFocus(true)

and now your buttons will catch focus

Answer 2

The solution to this is actually easier than I thought. You can simply add in your custom adapter's getView() method a setOnClickListener() for the buttons you're using.

Any data associated with the button has to be added with myButton.setTag() in the getView() and can be accessed in the onClickListener via view.getTag()

I posted a detailed solution on my blog as a tutorial.

Answer 3

I don't have much experience than above users but I faced this same issue and I Solved this with below Solution

<Button
        android:id="@+id/btnRemove"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_toRightOf="@+id/btnEdit"
        android:layout_weight="1"
        android:background="@drawable/btn"
        android:text="@string/remove" 
        android:onClick="btnRemoveClick"
        />

btnRemoveClick Click event

public void btnRemoveClick(View v)
{
    final int position = listviewItem.getPositionForView((View) v.getParent()); 
    listItem.remove(position);
    ItemAdapter.notifyDataSetChanged();

}

Isn't the platform solution for this implementation to use a context menu that shows on a long press?

Is the question author aware of context menus? Stacking up buttons in a listview has performance implications, will clutter your UI and violate the recommended UI design for the platform.

On the flipside; context menus - by nature of not having a passive representation - are not obvious to the end user. Consider documenting the behaviour?

This guide should give you a good start.

Answer 5

This is sort of an appendage @znq's answer...

There are many cases where you want to know the row position for a clicked item AND you want to know which view in the row was tapped. This is going to be a lot more important in tablet UIs.

You can do this with the following custom adapter:

private static class CustomCursorAdapter extends CursorAdapter {

    protected ListView mListView;

    protected static class RowViewHolder {
        public TextView mTitle;
        public TextView mText;
    }

    public CustomCursorAdapter(Activity activity) {
        super();
        mListView = activity.getListView();
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        // do what you need to do
    }

    @Override
    public View newView(Context context, Cursor cursor, ViewGroup parent) {
        View view = View.inflate(context, R.layout.row_layout, null);

        RowViewHolder holder = new RowViewHolder();
        holder.mTitle = (TextView) view.findViewById(R.id.Title);
        holder.mText = (TextView) view.findViewById(R.id.Text);

        holder.mTitle.setOnClickListener(mOnTitleClickListener);
        holder.mText.setOnClickListener(mOnTextClickListener);

        view.setTag(holder);

        return view;
    }

    private OnClickListener mOnTitleClickListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            final int position = mListView.getPositionForView((View) v.getParent());
            Log.v(TAG, "Title clicked, row %d", position);
        }
    };

    private OnClickListener mOnTextClickListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            final int position = mListView.getPositionForView((View) v.getParent());
            Log.v(TAG, "Text clicked, row %d", position);
        }
    };
}

For future readers:

To select manually the buttons with the trackball use:

myListView.setItemsCanFocus(true);

And to disable the focus on the whole list items:

myListView.setFocusable(false);
myListView.setFocusableInTouchMode(false);
myListView.setClickable(false);

It works fine for me, I can click on buttons with touchscreen and also alows focus an click using keypad
