How to add a button to a PreferenceScreen?

Question

I\'m quite new to Android Development and just came across Preferences. I found PreferenceScreen and wanted to create a login functionality with it. The only pr

Answer 1

For the xml:

<Preference
    android:title="Acts like a button"
    android:key="@string/myCoolButton"
    android:summary="This is a cool button"
/>

Then for the java in your onCreate()

Preference button = findPreference(getString(R.string.myCoolButton));
button.setOnPreferenceClickListener(new Preference.OnPreferenceClickListener() {
    @Override
    public boolean onPreferenceClick(Preference preference) { 
        //code for what you want it to do 
        return true;
    }
});

This will appear like a normal Preference, with just a title and a summary, so it will look like it belongs.

You can do it like this to access the button!

 View footerView = ((LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE)).inflate(R.layout.layoutButtons, null, false);

Don't forget to add android:id to the LinearLayout that contains the button in layoutButtons.xml, i.e. android:id="@+id/mylayout"

 LinearLayout mLayout = (LinearLayout) footerView.findViewById(R.id.mylayout);
 Button login = (Button) footerView.findViewById(R.id.loginButton);
 login.setOnClickListener(this);
 ListView lv = (ListView) findViewById(android.R.id.list);
 lv.addFooterView(footerView);

 // Lines 2 and 3 can be used in the same way for a second Button!

Add

setContentView(R.layout.buttonLayout);

Below

addPreferencesFromResource(R.xml.yourPreference);

buttonLayout:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

<RelativeLayout
        android:id="@+id/top_control_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content">
</RelativeLayout>

<LinearLayout
        android:id="@+id/bottom_control_bar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true">

    <Button
            android:id="@+id/button"
            android:layout_width="match_parent"
            android:layout_height="70dp"
            android:text="@string/saveAlarm"/>
</LinearLayout>

<ListView
        android:id="@android:id/list"
        android:layout_width="fill_parent"
        android:layout_height="0dip"
        android:layout_above="@id/bottom_control_bar"
        android:layout_below="@id/top_control_bar"
        android:choiceMode="multipleChoice">
</ListView>

Access Button by:

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        //Your event
    }
});

You can get the button on top or on bottom of the screen by putting the button in RelativeLayout:

• top_control_bar
• bottom_control_bar

bottom_control_bar

This worked for me. I hope I can help someone with this piece of code.

try android:onClick="myMethod" works like a charm for simple onclick events
