Android uses viewflipper animation to toggle screen effects _android

Sentiment: Viewflipper seemingly can be made into the new download application, the user first entered the general description. Finally, make a button, into the application.

1. First add the Viewflipper in the Main.xml file, then instantiate in Mainactivity, setcontext layout to get rid of the method of dynamically importing the data source.

Imported through a resid.length for loop. Creates a new ImageView getimageview (int resid) function for a ImageView object

Inside

Imageview.setimageresource (resid); wide height depends entirely on the size of the picture
Imageview.setbackgroundresource (RESID);//This will be adaptive.

Use the second one better. And then returns an object.

4 XML files were established under Res/anim, Left_in,left_out,right_in,right_out;

Example: Left_in to come in from the left

<translate
android:duration= "2000"//Duration 2s
android:fromxdelta= " -100%p"//
android:toxdelta= "0"/ >

There are 2 ways to implement this

(1) overridependingtransition (r.anim.left_in, r.anim.left_out);

Set time interval 
flipper.setflipinterval (3000);
Flipper.startflipping ();
This will achieve a similar slide effect

(2) Flipper.setinanimation (this, r.anim.left_in);

Flipper.setoutanimation (this, r.anim.left_out);
Setting the Viewflipper interval
flipper.setflipinterval (3000);
Start playing
//flipper.startflipping ();

Then load a Boolean ontouchevent (Motionevent event)

Set a global variable private Float startx;//the position of the finger when it falls

Get by Event.getaction ()

Case motionevent.action_down://Finger drop
{startx = Event.getx ();} --> gets the first horizontal coordinate case
motionevent.action_up://fingers leave
{by judging the event.getx ()-startx>100 to the right to slide, then animate, and show the front side
Startx-event.getx () <100 to slide to the left, then animate, and show the latter side
}
The gesture operation is in the up, and if there is a problem with layer folding in down. Through LOG.I ("Main", "number");

You can see that a little bit of the finger will appear a lot.

Case motionevent.action_move://Fingers Slide

The above is a small set of Android to introduce the use of Viewflipper animation screen effect, I hope to help you, if you have any questions please give me a message, small series will promptly reply to everyone. Here also thank you very much for the cloud Habitat Community website support!
