34. <item name= "Android:windowistranslucent" >false</item>
    
36. <item name= "Android:windowcontentoverlay" > @null </item>
    
38. <item name= "Android:windownotitle" >true</item>
    
40. <item name= "Android:windowbackground" > @color/white</item>

Copy Code
also if prompted

1. <item name= "Android:windowbackground" > @color/white</item>

Copy Code
If White is not found here, your project Res/values/color.xml no new or white color value, just add it in Res/values/color.xml

1. <color name= "White" > #ffffff </color>

Copy Code
This white value can be.

In addition, the view animation theme optional, the proposal also copied in, the effect is better, the code is as follows:

1. <font color= "#333333" ><font face= "Arial" > <style name= "Bottomtotopanim" parent= "Android:animation" >
   
2. <item name= "@android: Windowenteranimation" > @anim/bottomview_anim_enter</item>
   
3. <item name= "@android: Windowexitanimation" > @anim/bottomview_anim_exit</item>
   
4. </style></font></font>

Copy CodeRes/anim/bottomview_anim_enter.xml

1. <?xml version= "1.0" encoding= "Utf-8"?>
   
2. <set xmlns:android= "Http://schemas.android.com/apk/res/android" >
   
3. 
   
4. <translate
   
5. android:duration= "500"
   
6. Android:fromydelta= "100%p"/>
   
7. 
   
8. </set>

Copy Code
Res/anim/bottomview_anim_exit.xml

1. <?xml version= "1.0" encoding= "Utf-8"?>
   
2. <set xmlns:android= "Http://schemas.android.com/apk/res/android" >
   
3. 
   
4. <translate
   
5. android:duration= "500"
   
6. Android:toydelta= "100%p"/>
   
7. 
   
8. </set>

Copy Code


the whole is:

2, some core use code:

1. Bottomview Bottomview = new Bottomview (This,
   
2. R.style.bottomviewtheme_defalut, R.layout.bottom_view);
   
3. Bottomview.setanimation (R.style.bottomtotopanim);//Set animation, optional
   
4. Bottomview.showbottomview (FALSE);

Copy Code

If you want to get this view, call the. GetView () method.
