Simple Method for customizing the title of Android peferenceActivity

PeferenceActivity fully uses the defined layout.
Therefore, it cannot be customized like other good windows. Now we need to add
A custom title, such as adding a uniform topbar like other windows.
Assume that the topbar layout is title. xml.

I. Standard custom title bar method

Android provides custom title bar Methods
We can simply implement it.

@ Override
Protected void onCreate (Bundle savedInstanceState ){
Final boolean isCustom = requestWindowFeature (Window. FEATURE_CUSTOM_TITLE );
Super. onCreate (savedInstanceState );
SetContentView (R. layout. tab_setting );
AddPreferencesFromResource (R. xml. setting_preference );

If (isCustom)
GetWindow (). setFeatureInt (Window. FEATURE_CUSTOM_TITLE, R. layout. title );

}

But in Android 4.0, a message is displayed.

You cannot combine custom titles with other title features

There are many complex solutions available on the Internet. The key is that PerferenceActivtiy always fails.

2. Customize a perfence layout and use it as the first configuration item.

Add

<Preference android: layout = "@ layout/title" android: key = "app_info"/>

In this way, the pseudo title bar can be implemented. The disadvantage of this layout method is that the entire window cannot be filled, that is, there will be a white edge on both sides of the layout, which is very difficult to see.

3. Create a custom window layout

When querying data, we found that perferenceActivity supports full custom la S. To ensure a listView in the layout, its id is
Android: id = "@ android: id/list"

After addPreferencesFromResource (); is called, The perference list is automatically added to the listView. The title layout can be simply added to the listView.

This is a successful layout with very satisfactory results.

<? Xml version = "1.0" encoding = "UTF-8"?>

<LinearLayout xmlns: android = "http://schemas.android.com/apk/res/android" android: layout_width = "match_parent" android: layout_height = "match_parent" android: orientation = "vertical" android: background = "@ color/bg_color">

<Include android: id = "@ + id/title" layout = "@ layout/title"> </include>
<ListView android: id = "@ android: id/list" android: layout_width = "fill_parent" android: layout_height = "wrap_content" android: cacheColorHint = "@ color/transparent" android: scrollbarStyle = "outsideOverlay" android: fadingEdgeLength = "0dp" android: scrollbars = "none" android: fadingEdge = "none" android: listSelector = "#00000000"/>
</LinearLayout>

In addition, this will bring additional benefits: You can customize the perference list background color and so on.

In android development, how does one center the title, not a custom title? That is to say, xml is not required? If you can, paste the following method:

In the source code environment, you can modify the default Title layout file (screen_title.xml, etc.
It cannot be implemented in a non-source environment.
