Android 0 Basics section 49th: Adapterviewflipper picture Carousel

The last issue of the use of Expandablelistview, you have mastered it? This issue begins with the study of the use of adapterviewfilpper.

I. Understanding Adapterviewfilpper

Adapterviewfilpper inherits Adapterviewanimator, which also displays multiple view components provided by Adapter, but it can only display one view component at a time, and the program can pass showprevious () and Shownext () method controls that the component displays the previous, next component.

Adapterviewfilpper can use the fade fade animation effect during multiple view transitions. In addition, you can call the component's startflipping () to control it to "AutoPlay" the next view component.

The XML attributes supported by Adapterviewanimator are as follows:

• Android:animatefirstview: Sets whether animation is used when the first view of the display component is displayed.

• Android:inanimation: Sets the animation used when the component is displayed.

• Android:loopviews: Sets whether to automatically jump to the first component when looping to the last component.

• Android:outanimation: Sets the animation used when the component is hidden.

Adapterviewfilpper additional supported XML attributes and related methods are shown in the following table.

Ii. Examples of Adapterviewfilpper

Next, learn how to use adapterviewfilpper using a simple example program.

Continue to use the Listviewsample module of the Widgetsample project to create a adapterview_filpper_layout.xml file in the app/main/res/layout/directory populated with the following code snippet:

<?XML version= "1.0" encoding= "Utf-8"?><Relativelayoutxmlns:android= "Http://schemas.android.com/apk/res/android"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent">    <AdapterviewflipperAndroid:id= "@+id/flipper"Android:layout_width= "Match_parent"Android:layout_height= "Match_parent"Android:flipinterval= "the"Android:layout_alignparenttop= "true"/>    <ButtonAndroid:id= "@+id/prev_btn"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_alignparentbottom= "true"Android:layout_alignparentleft= "true"Android:text= "Previous"/>    <ButtonAndroid:id= "@+id/next_btn"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_alignparentbottom= "true"Android:layout_centerhorizontal= "true"Android:text= "Next"/>    <ButtonAndroid:id= "@+id/auto_btn"Android:layout_width= "Wrap_content"Android:layout_height= "Wrap_content"Android:layout_alignparentbottom= "true"Android:layout_alignparentright= "true"Android:text= "AutoPlay"/></Relativelayout>

Create a Myfilpperadapter class, inherit the Baseadapter class, and rewrite its 4 main methods, with the following code:

 PackageCom.jinyu.cqkxzsxy.android.listviewsample.adapter;ImportAndroid.content.Context;ImportAndroid.view.View;ImportAndroid.view.ViewGroup;ImportAndroid.widget.BaseAdapter;ImportAndroid.widget.ImageView;/*** @ Creator Xin 鱻 * @ description Android 0 Basic primer to Master Series tutorials, welcome to the public number Shareexpert*/ Public classMyfilpperadapterextendsBaseadapter {PrivateContext Mcontext =NULL; Private int[] Mimageids =NULL;  PublicMyfilpperadapter (Context context,int[] imageids) {         This. Mcontext =context;  This. Mimageids =Imageids; } @Override Public intGetCount () {returnmimageids.length; } @Override PublicObject GetItem (intposition) {        returnposition; } @Override Public LongGetitemid (intposition) {        returnposition; }    //The view returned by this method represents each list item@Override PublicView GetView (intposition, View Convertview, ViewGroup parent) {ImageView ImageView=NULL; if(NULL==Convertview) {            //Create a ImageViewImageView =NewImageView (Mcontext); //set the scale type of ImageViewImageview.setscaletype (ImageView.ScaleType.FIT_XY); //Set layout parameters for ImageViewImageview.setlayoutparams (Newviewgroup.layoutparams (ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT))            ; Convertview=ImageView; } Else{ImageView=(ImageView) Convertview; }        //set up a picture resource for ImageViewImageview.setimageresource (mimageids[position]); returnImageView; }}

Next, provide the adapter for Adapterviewfilpper, using the custom Baseadapter. Create a new Adapterviewfilperactivity.java file and load the new layout file above, with the following code:

 Packagecom.jinyu.cqkxzsxy.android.listviewsample;ImportAndroid.os.Bundle;Importandroid.support.v7.app.AppCompatActivity;ImportAndroid.view.View;ImportAndroid.widget.AdapterViewFlipper;ImportAndroid.widget.Button;ImportCom.jinyu.cqkxzsxy.android.listviewsample.adapter.MyFilpperAdapter; Public classAdapterviewfilperactivityextendsAppcompatactivityImplementsView.onclicklistener {PrivateAdapterviewflipper Mflipper =NULL; PrivateButton mprevbtn =NULL; PrivateButton mnextbtn =NULL; PrivateButton mautobtn =NULL; Private int[] Mimageids ={r.drawable.image_01,r.drawable.image_02,r.drawable.image_03, r.drawable.image_04,r.drawable.i    Mage_05,r.drawable.image_06, r.drawable.image_07,r.drawable.image_08,r.drawable.image_09}; @Overrideprotected voidonCreate (Bundle savedinstancestate) {Super. OnCreate (savedinstancestate);        Setcontentview (r.layout.adapterview_filpper_layout); //Get interface ComponentsMflipper =(Adapterviewflipper) Findviewbyid (r.id.flipper); MPREVBTN=(Button) Findviewbyid (R.ID.PREV_BTN); MNEXTBTN=(Button) Findviewbyid (R.ID.NEXT_BTN); MAUTOBTN=(Button) Findviewbyid (R.ID.AUTO_BTN); //set adapter for AdapterviewflipperMyfilpperadapter adapter =NewMyfilpperadapter ( This, Mimageids);        Mflipper.setadapter (adapter); //set up a click event listener for three buttonsMprevbtn.setonclicklistener ( This); Mnextbtn.setonclicklistener ( This); Mautobtn.setonclicklistener ( This); } @Override Public voidOnClick (view view) {Switch(View.getid ()) { Caser.id.prev_btn://Show Previous Componentmflipper.showprevious (); //Stop Auto Playmflipper.stopflipping ();  Break;  Caser.id.next_btn://displays the next component. Mflipper.shownext (); //Stop Auto Playmflipper.stopflipping ();  Break;  Caser.id.auto_btn://Start auto Playmflipper.startflipping ();  Break; default:                 Break; }    }}

The program code above calls Adapterviewflipper's Showprevious (), Shownext () method to control the component's display of the previous, next component, and calls the Startflipping () method to control AutoPlay.

Modify the program start activity, run the program, you can see the interface effect shown.

Click the previous or Next button to toggle the displayed component, click the AutoPlay button, and you will see adapterviewflipper change a picture every 5 seconds, using the fade fade effect when switching pictures.

At this point, the simple use of adapterviewflipper learning is complete, more properties and methods are recommended to practice and master.
