Here's how to turn activity into translucent. As follows:

2. The code is as follows:

Add a custom theme to the Styles.xml file

1     <stylename= "Mytranspaent">2         3         <Itemname= "Android:windowbackground">@color/transparent_background</Item>    4         <Itemname= "Android:windownotitle">True</Item>   5         <Itemname= "Android:windowistranslucent">True</Item>   6         <Itemname= "Android:windowanimationstyle">@+android:style/animation.translucent</Item>  7     </style>  

Activity of the Search interface:

1  Public classSecondactivityextendsActivity {2 3 @Override4     protected voidonCreate (Bundle savedinstancestate) {5         Super. OnCreate (savedinstancestate);6 Setcontentview (r.layout.activity_second);7     }8 9 @OverrideTen      Public BooleanOncreateoptionsmenu (Menu menu) { One         //inflate the menu; This adds items to the action bar if it is present. A getmenuinflater (). Inflate (R.menu.second, menu); -         return true; -     } the  - @Override -      Public Booleanontouchevent (Motionevent event) { -  +         Switch(Event.getaction ()) { -          CaseMotionevent.action_down: +Secondactivity. This. Finish (); A              Break; at  -         default: -              Break; -         } -  -         return Super. Ontouchevent (event); in     } -  to}

Activity_second.xml file:

1 <LinearLayoutxmlns:android= "Http://schemas.android.com/apk/res/android"2 Xmlns:tools= "Http://schemas.android.com/tools"3 Android:layout_width= "Match_parent"4 Android:layout_height= "Match_parent"5 android:orientation= "Horizontal"6 Tools:context=". Secondactivity " >7 8     <EditText9         Android:id= "@+id/ed"Ten Android:layout_width= "Wrap_content" One Android:layout_height= "Wrap_content" A Android:layout_weight= "1.0" - Android:background= "#F8F8FF" - Android:drawableleft= "@drawable/ic_search_normal" the Android:hint= "Please enter what you want to query" - Android:textcolor= "#000033" /> -  - </LinearLayout>

Inside the main interface is a button that pops up the activity.

1  Public classMainactivityextendsActivity {2 3 @Override4     protected voidonCreate (Bundle savedinstancestate) {5         Super. OnCreate (savedinstancestate);6 Setcontentview (r.layout.activity_main);7 8Findviewbyid (R.id.button01). Setonclicklistener (NewOnclicklistener () {9 Ten @Override One              Public voidOnClick (View v) { AIntent i =NewIntent (); -I.setclass (mainactivity. This, Secondactivity.class); - startactivity (i); the             } -         }); -  -     } +  -}

The key is to add theme to the popup activity in the Manifest.xml file.

1   < Activity 2             Android:name = "Com.example.compass.SecondActivity" 3             android:label= "@string/title_activity_second"4            android:theme  = "@style/mytranspaent">5   </activity >
