java - How to launch an android app(not an activity) from the bottom of the screen to top? -


i have used overridependingtransition()already used open activity given transition not app.

moreover works when having intent on clicking on button, won't work if use overridependingtransition() in oncreate()

  @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         setcontentview(r.layout.activity_main2);         intent = new intent(main2activity.this,mainactivity.class);         startactivity(i);         overridependingtransition(r.anim.slide_in_up,r.anim.slide_out_up);     } 

before setcontentview use following code :

overridependingtransition(r.anim.slide_in_from_bottom, r.anim.fade_out); 

and in finish() use following code :

@override     public void finish() {         super.finish();         overridependingtransition(r.anim.fade_in, r.anim.slide_out_back_to_bottom);     } 

and create anim folder , put these files :

slide_in_from_bottom:

<set xmlns:android="http://schemas.android.com/apk/res/android"      android:zadjustment="top">     <translate             android:duration="400"             android:fromydelta="100%p"             android:toydelta="0%p"             >     </translate>     <alpha             android:fromalpha="0.8"             android:toalpha="1.0"             android:duration="400"             /> </set> 

slide_out_back_to_bottom:

 <set xmlns:android="http://schemas.android.com/apk/res/android"          android:zadjustment="top">         <translate                 android:duration="400"                 android:fromydelta="0%p"                 android:toydelta="100%p"                 >         </translate>         <alpha                 android:fromalpha="1.0"                 android:toalpha="0.8"                 android:duration="400"                 />     </set> 

fade_in:

<set xmlns:android="http://schemas.android.com/apk/res/android"      android:zadjustment="bottom">     <alpha             android:fromalpha="0.0"             android:toalpha="1.0"             android:duration="300"             /> </set> 

fade_out:

<set xmlns:android="http://schemas.android.com/apk/res/android"      android:zadjustment="bottom">     <alpha             android:fromalpha="1.0"             android:toalpha="0.0"             android:duration="200"             /> </set>
