Android in customize activity and dialog position size background and transparency etc Demo

1. Customize Activity Display Style

First build the Colors.xml file under Res/values, write:

[XHTML]View Plaincopy

2. <? XML version= "1.0" encoding="Utf-8"?>
4. <resources>
6. <!--Set the transparency to 56% (9/16) and so on
8. <color name="Transparent"> #9000</color>
10. </Resources>

This value sets the transparency of the entire interface, and is now set to about 56% (9/16) of the transparency to see the effect.

Then build Styles.xml under Res/values/, set the style of the program

[XHTML]View Plaincopy

2. <? XML version= "1.0" encoding="Utf-8"?>
4. <resources>
6. <mce:style name="Transparent"><!--
8. Set background--
10. <item name="Android:windowbackground"> @color/transparent</Item>
12. <!--set the bottom visible --
14. <item name="android:windowistranslucent">true</Item>
16. <!--set Jump effects --
18. <item name="Android:windowanimationstyle">@+android:style/animation.translucent </Item>
22. --></mce:style><style name="Transparent" mce_bogus="1" > Setting background-->
24. <item name="Android:windowbackground"> @color/transparent</Item >
26. <!--set the bottom visible --
28. <item name="android:windowistranslucent">true</Item>
30. <!--set Jump effects --
32. <item name="Android:windowanimationstyle">@+android:style/animation.translucent </Item>
34. </style>
36. </Resources>

Note: The MCE section is automatically generated for postings and is not actually required.

The last step is to use this styles.xml in the corresponding activity. That is, add any <activity> tags in the androidmanifest.xml
Android:theme = "@style/transparent"
If you want to set all the activity to use this style, you can add this tag statement in <application>.
Finally run the program, Haha, is not found that the entire interface is covered with a layer of translucent. Finally can change the background color #9000 to #0000, after running the program, it is completely transparent, see the background of all things can be invalid operation. Oh....

2. Display the activity as dialog and customize the style

First build the Bgconfig.xml file under Res/drawable, write:

[XHTML]View Plaincopy

2. <? XML version= "1.0" encoding="Utf-8"?>
4. <shape xmlns:android="http://schemas.android.com/apk/res/android">
6. <solid android:color="#ffffff" />
8. <stroke android:width="3DP" color="#000000" />
10. <corners android:radius="3DP" />
12. <padding android:left="3DP" android:top="3DP" android:right="3DP"
14. android:bottom="3DP" />
16. </shape>

Then build Styles.xml under Res/values/, set the style of the program

[XHTML]View Plaincopy

2. <? XML version= "1.0" encoding="Utf-8"?>
4. <resources>
6. <!--setting Styles --
8. <mce:style name="theme.myactivity" parent="Android:style/theme.dialog" mce_bogus= "1" mce_bogus="1"><!--
10. <item name= "Android:windowbackground" > @drawable/bgconfig</item>
13. -</mce:style><style  name= "theme.myactivity"   Parent= "Android:style/theme.dialog"  mce_bogus= "1"  mce_bogus= "1"  < span class= "attribute" >mce_bogus= "1" >      <item name=" Android:windowbackground "> @drawable/bgconfig</< Span class= "Tag-name" >item>  
15. </style>
17. </Resources>

Note: The MCE section is automatically generated for postings and is not actually required.

The last step is to use this styles.xml in the corresponding activity. That is, add any <activity> tags in the androidmanifest.xml
Android:theme = "@style/transparent"

3. Setting the window size and position

[Java]View Plaincopy

2. WindowManager m = Getwindowmanager ();
4. Display d = m.getdefaultdisplay (); //To get the screen width, height
8. Layoutparams p = GetWindow (). GetAttributes (); //Gets the current parameter value of the dialog box
10. P.height = (int) (D.getheight () * 1.0); //Height set to 1.0 of the screen
12. P.width = (int) (D.getwidth () * 0.7); //Width set to 0.8 of the screen
14. P.alpha = 1.0f; //Set itself transparency
16. P.dimamount = 0.0f; //Set Dark degrees
20. GetWindow (). SetAttributes (P); //settings take effect
22. GetWindow (). setgravity (Gravity.right); //Set Align Right
