Android PreferencesActivity and custom Header

Question

I have a standard PreferencesActivity declared in the following way:

public class PreferencesActivity extends PreferenceActivity{
   ...
}

Then inside the activity I load my Fragment in the following way:

@Override
protected void onCreate(Bundle savedInstanceState) {

    super.onCreate(savedInstanceState);

    getFragmentManager().beginTransaction()
       .replace(android.R.id.content, new GraphicsFragment())
       .commit();
}

And this is my Fragment:

public static class GraphicsFragment extends PreferenceFragment {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        // Load the preferences from an XML resource
        addPreferencesFromResource(R.xml.warrior_preference);
    }
}

Right now the Activity is completely covered by this Fragment, but what I need is to have an ImageView on top and then the Fragment activity loaded within a ScrollView or something similar. Is this possible?

You can try below. Create activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" 
    android:id="@+id/activity_main_layout">

    <ImageView
        android:id="@+id/image"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:src="@drawable/some image" />

    <FrameLayout android:id="@+id/fragment"
        android:layout_width="match_parent" 
        android:layout_height="wrap_content" 
        android:layout_below="@id/image"/>

</RelativeLayout>

In PreferencesActivity onCreate method use below write

    Fragment newFragment = new GraphicsFragment();
    FragmentManager fm = getFragmentManager();
    FragmentTransaction ft = fm.beginTransaction();
    ft.replace(R.id.fragment, newFragment).commit();;

Inside ImageView give your drawable image. Please go through below urls for PreferencesActivity creation.

It doesn't work. I get this error Unable to start activity ComponentInfo{xxx.PreferencesActivity}: java.lang.RuntimeException: Your content must have a ListView whose id attribute is 'android.R.id.list' – Raffaeu Dec 30 '15 at 16:39

@Raffaeu, I have update my answer and also check http://stackoverflow.com/questions/6647831/android-your-content-must-have-a-listview-whose-id-attribute-is-android-r-id-li or http://stackoverflow.com/questions/11050817/your-content-must-have-a-listview-whose-id-attribute-is-android-r-id-list – Mohammad Tauqir Dec 30 '15 at 16:56
I'll have a look at this – Raffaeu Dec 30 '15 at 16:56
This is the correct answer http://stackoverflow.com/questions/30139548/how-to-add-toolbar-in-preferenceactivity Preferences activity needs a listview to hold the preferences fragment and not a fragment or frame layout – Raffaeu Dec 30 '15 at 17:00

Yes this is possible. You need to place the fragment inside a specified view in the parent view.

You can also place the fragment directly into your XML file, if it is not necessary to inflate the fragment programmaticly.

Yes what you're trying to achieve is completely possible. What can be done to achieve this is applying an imageView and a frameLayout in a layout:

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/viewGroup"
android:orientation="vertical"
tools:context="com.android.empty.MainActivity">

<ImageView
    android:layout_width="match_parent"
    android:layout_height="140dp"
    android:background="@drawable/c1"
    android:scaleType="centerCrop"/>

<FrameLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:id="@+id/frame"></FrameLayout>

</LinearLayout>

Now change, changing the id of inside the replace method from android.R.id.content to R.id.frame will do the trick.

getFragmentManager().beginTransaction()
            .replace(R.id.frame, new GraphicsFragment())
            .commit();

    //Do what ever you want to with imageview.

Actually, android.R.id.content gives the root view in return so the fragment completely covers the layout.
