Android instance-Mobile security Defender (21)-Custom activity interface Toggle Animation

First, the goal.

Enables animation transitions between the two activity interfaces.

Second, the code implementation.

1. Create a new folder named Anim under the Res folder.

2. Create a new Android XML file (named Tran_out) in the new Anim folder, select the root element (in this case, translate) according to the animation requirements to animate the activity interface to move out of the screen.

3. In the new XML file, in the properties of the root tag <translate>, the namespace is automatically incremented when a property is entered. The Android:fromxdelta property represents the x-axis from which the origin is the upper-left corner of the screen, the length of the 100%p is exactly equal to the width of the screen (or parent component), and the minus sign can represent the other side. The Android:toxdelta property indicates which x axis to go to.

Move-out screen (tran_out.xml) file code:

1 <?xml version= "1.0" encoding= "Utf-8"?>2 <translate xmlns:android= "/http Schemas.android.com/apk/res/android "3     android:fromxdelta=" 100%p "4     android:toxdelta=" 0 "5     android:duration="6     android:fromydelta= "0"7     Android:toydelta = "0" >89 </translate>

4, the same production into the screen (Tran_in.xml) animation effect, the code is as follows:

1 <?xml version= "1.0" encoding= "Utf-8"?>2 <translate xmlns:android= "/http Schemas.android.com/apk/res/android "3     android:fromxdelta=" 100%p "4     android:toxdelta=" 0 "5     android:duration="6     android:fromydelta= "0"7     Android:toydelta = "0" >89 </translate>

5. In the Click event processing method that needs to place the animation, the overridependingtransition (int enteranim, int exitanim) method must be executed after the startactivity () or the finish () method, where the parameter int Enteranim is the ID that enters the animation file (tran_in.xml), the parameter int Exitanim is the ID of the move-out animation file (Tran_in.xml).

The Setup Wizard ui_1 click the event method (next) code, other similar:

1 //Next Click event2      Public voidNext (view view) {3Intent Intent =NewIntent (setupwizard_ui_1. This, Setupwizard_ui_2.class);4 startactivity (intent);5 finish ();6         //required to be executed behind finish () or startactivity (intent). 7 overridependingtransition (r.anim.tran_in, r.anim.tran_out);8}
