How do I create one Preference with an EditTextPreference and a Togglebutton?

Question

What I'm trying to implement is basically and exact replica of the image below (the preferences that I've squared). Pressing anything to the left of the preference should open up a dialog. Pressing the togglebutton will disable/enable whatever I'm setting in this preference.

I've been trying for hours now and I've come up empty-handed. How do I implement this in a PreferenceActivity?

EDIT: It seems people are misunderstanding my question. It is very important that I figure out how to solve my problem using a PreferenceActivity. NOT an Activity. I don't care whether I need to do it in XML or programatically. Just please refrain from providing me with answers that I cannot use within a or something similar.

EDIT 2 : Added a bounty - I really need an answer to this

Answer 1

Hell man, I like your idea :-)

This is just same as @MH's answer, but more concise.

I tested with ToggleButton, not Switch.

package android.dumdum;

import android.content.Context;
import android.preference.Preference;
import android.util.AttributeSet;
import android.view.View;
import android.view.ViewGroup;
import android.widget.LinearLayout;
import android.widget.TextView;
import android.widget.ToggleButton;

public class TogglePreference extends Preference {

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

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

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

    public View getView(View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = new LinearLayout(getContext());
            ((LinearLayout) convertView)
                    .setOrientation(LinearLayout.HORIZONTAL);

            TextView txtInfo = new TextView(getContext());

            txtInfo.setText("Test");
            ((LinearLayout) convertView).addView(txtInfo,
                    new LinearLayout.LayoutParams(
                            LinearLayout.LayoutParams.MATCH_PARENT,
                            LinearLayout.LayoutParams.WRAP_CONTENT, 1));

            ToggleButton btn = new ToggleButton(getContext());
            ((LinearLayout) convertView).addView(btn);
        }

        return convertView;
    }
}

And the preferences.xml:

<?xml version="1.0" encoding="utf-8"?>
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android" >

    <PreferenceCategory android:title="Test custom preferences" >
        <android.dumdum.EncryptorEditTextPreference />
        <android.dumdum.TogglePreference />
    </PreferenceCategory>

</PreferenceScreen>

EncryptorEditTextPreference is not related to your question, but it uses same technique (extending EditTextPreference).
