This article began to implement the Carousel map campaign, this article first to make the picture slide up (viewpager), the effect is as follows:

First implement the layout

<Relativelayoutxmlns: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"Tools:context=". Mainactivity " >    <RelativelayoutAndroid:layout_width= "Match_parent"Android:layout_height= "160DP" >        <Android.support.v4.view.ViewPagerAndroid:id= "@+id/viewpager"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent" />        <LinearLayoutAndroid:layout_width= "Match_parent"Android:layout_height= "40DP"Android:layout_alignparentbottom= "true"Android:background= "#66000000"android:gravity= "Center_horizontal"android:orientation= "vertical"android:padding= "5DP" >            <TextViewAndroid:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:singleline= "true"Android:text= "Harmonious society, harmonious Society, harmonious society, harmonious society"Android:textcolor= "@android: Color/white" />            <LinearLayoutAndroid:id= "@+id/ll_point_container"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_margintop= "5DP"android:orientation= "Horizontal" >            </LinearLayout>        </LinearLayout>    </Relativelayout></Relativelayout>

The following error occurred while running the project:

09-28 09:08:44.032:e/androidruntime (5794): java.lang.RuntimeException:Unable to start activity componentinfo{ Com.wuyudong.viewpager/com.wuyudong.viewpager.mainactivity}: Android.view.InflateException:Binary XML file Line #11 : Error Inflating class Android.support.v4.view.ViewPager

Viewpager is a great, powerful control that many apps use to achieve cool results, but in many cases you run into error inflating class Android.support.v4.view.ViewPager This question,

The solution to this problem is simple: Right-click Project selection Build Path - Configure Build Path , and then select Order and Export options. Sticky Android-support-v4.jar and check this option, and then Clean under the project, the recompilation problem is solved ~

Then write the logic code:

 PackageCom.wuyudong.viewpager;Importjava.util.ArrayList;ImportAndroid.os.Bundle;Importandroid.app.Activity;ImportAndroid.support.v4.view.PagerAdapter;ImportAndroid.support.v4.view.ViewPager;ImportAndroid.view.Menu;ImportAndroid.view.View;ImportAndroid.view.ViewGroup;ImportAndroid.widget.BaseAdapter;ImportAndroid.widget.ImageView; Public classMainactivityextendsActivity {PrivateViewpager Viewpager; Private int[] imageresids; PrivateArraylist<imageview>imageviewlist; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (R.layout.activity_main); //Initialize Layout view Viewinitviews (); //Model DataInitData (); //controller ControllersInitadapter (); }    Private voidinitviews () {Viewpager=(Viewpager) Findviewbyid (R.id.viewpager); Imageresids=New int[] {r.drawable.a, r.drawable.b, r.drawable.c, R.DRAWABLE.D, R.DRAWABLE.E}; Imageviewlist=NewArraylist<imageview>();        ImageView ImageView;  for(inti = 0; i < imageresids.length; i++) {ImageView=NewImageView ( This);            Imageview.setbackgroundresource (Imageresids[i]);        Imageviewlist.add (ImageView); }    }    Private voidInitadapter () {//    }    Private voidInitData () {//initialize the data to be displayedViewpager.setadapter (NewMyadapter ()); }    classMyadapterextendsPageradapter {@Override Public intGetCount () {returnimageviewlist.size (); }        //3. The judgment logic of the specified multiplexing@Override Public Booleanisviewfromobject (View view, Object object) {//when you slide to a new entry and return to it, the view can be reused .            returnView = =object; }        //1. Return the contents of the entry to be displayed, create an entry@Override PublicObject Instantiateitem (ViewGroup container,intposition) {            //container: Container: Viewpager//Position: The current location of the entry to be displayedImageView ImageView =Imageviewlist.get (position); //A. Add the View object to the containerContainer.addview (ImageView); //B. Return the view object to the frame, adapter            returnImageView;//must be overridden, otherwise thrown exception        }        //2. Destruction of Entries@Override Public voidDestroyitem (ViewGroup container,intposition, Object object) {            //object to destroyContainer.removeview ((View) object); }    }}

After running the project, the effect is as follows:
