Remarks

Represents a top-level Preference that is the root of a Preference hierarchy. A PreferenceActivity points to an instance of this class to show the preferences. To instantiate this class, use PreferenceManager#createPreferenceScreen(Context). <ul> This class can appear in two places: <li> When a PreferenceActivity points to this, it is used as the root and is not shown (only the contained preferences are shown). <li> When it appears inside another preference hierarchy, it is shown and serves as the gateway to another screen of preferences (either by showing another screen of preferences as a Dialog or via a Context#startActivity(android.content.Intent) from the Preference#getIntent()). The children of this PreferenceScreen are NOT shown in the screen that this PreferenceScreen is shown in. Instead, a separate screen will be shown when this preference is clicked. </ul>

Here's an example XML layout of a PreferenceScreen:

&lt;PreferenceScreen
                    xmlns:android="http://schemas.android.com/apk/res/android"
                    android:key="first_preferencescreen"&gt;
                &lt;CheckBoxPreference
                        android:key="wifi enabled"
                        android:title="WiFi" /&gt;
                &lt;PreferenceScreen
                        android:key="second_preferencescreen"
                        android:title="WiFi settings"&gt;
                    &lt;CheckBoxPreference
                            android:key="prefer wifi"
                            android:title="Prefer WiFi" /&gt;
                    ... other preferences here ...
                &lt;/PreferenceScreen&gt;
            &lt;/PreferenceScreen&gt;

In this example, the "first_preferencescreen" will be used as the root of the hierarchy and given to a PreferenceActivity. The first screen will show preferences "WiFi" (which can be used to quickly enable/disable WiFi) and "WiFi settings". The "WiFi settings" is the "second_preferencescreen" and when clicked will show another screen of preferences such as "Prefer WiFi" (and the other preferences that are children of the "second_preferencescreen" tag).
