Custom Preference - Button not clickable

Solution 1:

onPreferenceClick is triggered when the Prefererence has been clicked not when you click the button. If you want to catch the button click you need to set a OnClickListener on the button itself. The problem is to retrieve the inflated button since the Preference class doesn't have a findViewById method or anything similar. Here's how I'd do it:

1. Create a custom Preference class and override the onCreateView
2. In the onCreateView method you grab the inflated layout from the super class and find the Button
3. Add an OnClickListener to the button
4. Use your custom Preference class in your preference layout file

public class CustomPreference extends Preference  {

    public CustomPreference(Context context) {
        super(context);
    }

    public CustomPreference(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomPreference(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    protected View onCreateView(ViewGroup parent) {
        View preferenceView = super.onCreateView(parent);

        setOnClickListener(preferenceView);

        return preferenceView;
    }

    private void setOnClickListener(View preferenceView) {
        if (preferenceView != null && preferenceView instanceof ViewGroup) {
            ViewGroup widgetFrameView = ((ViewGroup)preferenceView.findViewById(android.R.id.widget_frame));
            if (widgetFrameView != null) {
                // find the button
                Button theButton = null;
                int count = widgetFrameView.getChildCount();
                for (int i = 0; i < count; i++) {
                    View view = widgetFrameView.getChildAt(i);
                    if (view instanceof Button) {
                        theButton = (Button)view;
                        break;
                    }
                }

                if (theButton != null) {
                    // set the OnClickListener
                    theButton.setOnClickListener(new OnClickListener() {
                        @Override
                        public void onClick(View v) {
                            // do whatever you want to do
                        }
                    });
                }
            }
        }
    }
}

This replaces the Preference in your xml file:

<yourpackage.CustomPreference
    android:key="your_id"
    android:title="@string/your_title"
    android:summary="@string/your_summary"/>

Solution 2:

I would use something similar to the code below to implement this:

@Override
protected View onCreateView (ViewGroup parent) {
    LayoutInflater inflater = (LayoutInflater)   getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View customRow = inflater.inflate(R.layout.preferences_station_list_row, null);
    ((ImageButton) customRow.findViewById(R.id.pref_delete_station)).setOnClickListener(new OnClickListener() {      
        @Override
        public void onClick(View v) {
           //perform whatever you need to button to do here.
        }
    });

    customRow.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            showDialog(null);
        }
    });
    customRow.setClickable(true);
    return customRow;
}

Has this solved your issue?
