I am developing app with minSdkVersion="11", that is app for tablets and Android 4.0 and newer. I have scrutinized internet on this topic, but have not found much.
To implement custom layout for previous versions of Android SDK we just have to create layout (say preference.xml) with ListView and its id equals to android.R.id.list and use setContentView method.
preference.xml:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent" />
</RelativeLayout>
In Android 3.0 things have changed and Preferences are implemented with use of fragments. That is how my preference_headers.xml file looks like:
<preference-headers
xmlns:android="http://schemas.android.com/apk/res/android">
<header android:fragment="com.example.MyPreferenceActivity$GeneralSettingsFragment"
android:title="General"
android:summary="Common settings." />
<header
android:title="Example.com" >
<intent android:action="android.intent.action.VIEW"
android:data="http://www.example.com" />
</header>
</preference-headers>
MyPreferenceActivity.java:
public class MyPreferenceActivity extends PreferenceActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.preference);
// Add a button to the header list.
if (hasHeaders()) {
Button button = new Button(this);
button.setText("Log out");
setListFooter(button);
}
}
/**
* Populate the activity with the top-level headers.
*/
@Override
public void onBuildHeaders(List<Header> target) {
loadHeadersFromResource(R.xml.preference_headers, target);
}
public static class GeneralSettingsFragment extends PreferenceFragment {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Load the preferences from an XML resource
addPreferencesFromResource(R.xml.fragmented_preferences);
}
}
}
Now if I run MyPreferenceActivity I will see this error in LogCat:
> java.lang.IllegalArgumentException: No view found for id 0x10202be for
> fragment GeneralSettingsFragment{4077f8c0 #0 id=0x10202be}

> E/AndroidRuntime(17103): at
> android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1724)
> E/AndroidRuntime(17103): ... 11 more
I know what causes this problem. FragmentManager just cannot find a view to insert fragment GeneralSettingsFragment in. But I don't know how to solve it.
By the way, if I run the same app on Android 4.0, then I can see the first Preference Activity with headers. But if I click on General, app will crash and I will receive similar error in LogCat:
java.lang.IllegalArgumentException: No view found for id 0x10202cd for fragment GeneralSettingsFragment{4134b4e0 #0 id=0x10202cd}

I had the same issue than you.
I tried a lot of stuff but here is my full code:
https://github.com/iRail/BeTrains-for-Android/blob/master/src/tof/cv/mpp/MyPreferenceActivity.java
The trick is to add the setContentView in the onBuildHeaders section, but NOT in the onCreate.
I also made some tests in fragment and not perfectly sure why this is working, but I promise you: I have a custom layout on tablet header section!
i tried this code for my application
<PreferenceScreen xmlns:android="http://schemas.android.com/apk/res/android">
<PreferenceCategory android:title="@string/PreferencesActivity.GeneralSettingsCategoryTitle">
<Preference
android:title="yor title"
android:summary="your summary"
android:key="key to access preference" />
<Preference
android:title="@string/"
android:summary="@string/"
android:key="key2" />
<PreferenceScreen
android:key="key3"
android:title="@string/"
android:summary="@string/">
<CheckBoxPreference
android:title="@string/"
android:defaultValue="false"
android:summary="@string/"
android:key="key4" />
<CheckBoxPreference
android:title="@string/"
android:defaultValue="true"
android:summary="@string/"
android:key="key5" />
<ListPreference
android:title="@string/"
android:summary="@string/"
android:key="key6"
android:defaultValue="buttons"
android:entries="@array/"
android:entryValues="@array/" />
....
</prefefenceScreen>
</preferenceCategory>
</preferenceScreen>
enter code here
you do not need to setContenView. in this example case the layout population is done via headers and associated fragments, another words automatically.
