Android control Imageswitcher to achieve left and right picture switching function _android

The Imageswitcher class is a subclass of the Viewswitcher class, and its effect is to perform imageview transitions and animate. The following two steps are required to use this class:

1 provides a viewfactory for the Imageswitcher class, the view component that Viewfactory generates must be ImageView.

2 need to switch, only need to use the Imageswitcher setimagedrawable (), Setimageresource (), Setimageurl () method can be switched.

Activity_main.xml:

<linearlayout xmlns:android= "http://schemas.android.com/apk/res/android" xmlns:tools= "http:// Schemas.android.com/tools "android:layout_width=" match_parent "android:layout_height=" Match_parent "Android:o" rientation= "Vertical" tools:context= ".

Main_activity.java:

Package com.example.android_imageswitcher1;
Import android.app.Activity;
Import Android.os.Bundle;
Import Android.view.View;
Import Android.view.View.OnClickListener;
Import Android.widget.Button;
Import Android.widget.ImageSwitcher;
Import Android.widget.ImageView;

Import Android.widget.ViewSwitcher.ViewFactory;  public class Mainactivity extends activity implements Viewfactory, Onclicklistener {imageswitcher Mimageswitcher =
  Null
  Button btn1, btn2;
  int index = 0;

  int[] Resid = new INT[9];
    @Override protected void OnCreate (Bundle savedinstancestate) {super.oncreate (savedinstancestate);
    Setcontentview (R.layout.activity_main);
    Mimageswitcher = (imageswitcher) This.findviewbyid (R.id.imageswitcher);
    BTN1 = (Button) This.findviewbyid (r.id.back);
    BTN2 = (Button) This.findviewbyid (R.id.forward);
    Btn1.setonclicklistener (this);
    Btn2.setonclicklistener (this);
    Mimageswitcher.setfactory (this); Mimageswitcher.setinanimation (this, Android.) R. Anim.slide_in_left); Mimageswitcher.setoutanimation (this, Android.)
    R.anim.slide_out_right);
    Initresources ();
    if (Resid.length > 0) {mimageswitcher.setimageresource (resid[0]);
    } public void Initresources () {resid[0] = R.drawable.adobe;
    RESID[1] = r.drawable.android;
    RESID[2] = r.drawable.circle;
    RESID[3] = R.drawable.digg;
    RESID[4] = R.drawable.flower;
    RESID[5] = R.drawable.gmail;
    RESID[6] = R.drawable.imdb;
    RESID[7] = R.drawable.photo;
  RESID[8] = R.drawable.point;
  @Override public View Makeview () {return new ImageView (mainactivity.this);
    @Override public void OnClick (view view) {int action = View.getid ();
      Switch (action) {case r.id.back:index--;
      if (Index < 0) {index = resid.length-1;
      } mimageswitcher.setimageresource (Resid[index]);
    Break
      Case r.id.forward:index++;
if (Index > resid.length-1) {index = 0;      } mimageswitcher.setimageresource (Resid[index]);
    Break
    Default:break;

 }

  }

}

The effect of the implementation is as follows:
