Android Application Form Display status action (Requestwindowfeature () application) (reproduced)

Transferred from: http://www.cnblogs.com/salam/archive/2010/11/30/1892143.html

We are developing programs that often require full screen display of software, custom titles (using controls such as buttons) and other requirements, and today this is how to control the form display of Android applications.

First of all, an important approach is requestwindowfeature (Featrueid), which is the ability to enable the extended nature of the form. Parameters are constants defined in the window class.

One, enumeration constants

1.default_features: System default state, generally do not need to specify

2.feature_context_menu: Enable ContextMenu, which is enabled by default, generally does not need to specify

3.feature_custom_title: Custom caption. You must specify when you want to customize the caption. such as: When the caption is a button

4.feature_indeterminate_progress: Indeterminate Progress

5.feature_left_icon: Icon to the left of the title bar

6.feature_no_title: Wu Title

7.feature_options_panel: Enable the Options Panel feature, which is enabled by default.

8.feature_progress: Progress indicator function

9.feature_right_icon: Icon to the right of the title bar

Second, detailed

1.feature_custom_title detailed

This.requestwindowfeature (Window.feature_custom_title);
Setcontentview (R.layout.main);

Figure 2 Untitled

This is because Featrue is not set

After the above code add: GetWindow (). Setfeatureint (Window.feature_custom_title, r.layout.title);

　

Figure 3 Customizing the title

Custom caption completion, which is an XML file layout

Title.xml

<?xml version= "1.0" encoding= "Utf-8"?>
<linearlayout
xmlns:android= "Http://schemas.android.com/apk/res/android"
android:layout_width= "Wrap_content"
android:layout_height= "Wrap_content" >
 
<imageview android:layout_width= "Wrap_content"
android:layout_height= "Wrap_content"
android:src= "@drawable/icon"/>
<textview android:id= "@+id/text"
         android:layout_width= "wrap_content"  
        android:layout_height= "wrap_content"  
        Android:layout_ Alignparentleft= "true"  
        android:text= "text"/> 
 
</LINEARLAYOUT>

3.feature_indeterminate_progress detailed

android:layout_height= "Wrap_content"

Android:layout_gravity= "Center_vertical"
style= "Android:attr/progressbarstylesmalltitle" >

</ProgressBar>
</LinearLayout>

2.Java code

This.requestwindowfeature (window.feature_indeterminate_progress);
Setcontentview (R.layout.main);

GetWindow (). Setfeatureint (window.feature_indeterminate_progress, r.layout.progress);
Setprogressbarindeterminatevisibility (TRUE);

 

3.feature_left_icon detailed
