Use of gallery and Imageswitcher in Android

The effect is as follows:

The layout file Activity_main.xml as follows:

<Relativelayout 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:paddingbottom="@dimen/activity_vertical_margin"    Android:paddingleft="@dimen/activity_horizontal_margin"    Android:paddingright="@dimen/activity_horizontal_margin"    Android:paddingtop="@dimen/activity_vertical_margin"    Tools:context=". Mainactivity ">    <imageswitcherandroid:id="@+id/imageswitcher"android:layout_width= "Wrap_content" android:layout_height="Wrap_content"android:layout_weight="2"android: Paddingtop="30px" >                                            </imageswitcher>    <Galleryandroid:id= "@+id/gallery1"android:layout_width="Match_ Parent "android:layout_height=" Wrap_content "android:layout_weight=" 1 " android:spacing="5px"android:unselectedalpha="0.6" />                                                </relativelayout>

The Mainactivity.java code is as follows:

Import Android. App. ActionBar. Layoutparams;Import Android. App. Activity;Import Android. OS. Bundle;Import Android. View. View;Import Android. View. Animation. Animationutils;Import Android. Widgets. Adapterview;Import Android. Widgets. Adapterview. Onitemselectedlistener;Import Android. Widgets. Gallery;Import Android. Widgets. Imageswitcher;Import Android. Widgets.

D+ U. drawable. E-3. drawable. FR. drawable. G-3. drawable. h-3. drawable. I-3. drawable. JR. drawable. K};Private Imageswitcher Imageswitcher;Private Gallery Gallery;@Override protected void OnCreate (Bundle savedinstancestate) {Super. OnCreate(savedinstancestate);Setcontentview (R. Layout. Activity_main);Imageswitcher = (Imageswitcher) This. Findviewbyid(R. ID. Imageswitcher);Gallery = (gallery) This. Findviewbyid(R. ID. Gallery1);Set the animation effect Imageswitcher. Setinanimation(animationutils. Loadanimation(This, Android. R. Anim. Fade_in));Imageswitcher. Setoutanimation(animationutils. Loadanimation(This, Android. R. Anim. Fade_out));Imageswitcher. Setfactory(New Viewfactory () {@Override public View Makeview () {ImageView ImageView = new Ima Geview (mainactivity. this);ImageView. Setscaletype(ImageView. ScaleType. FIT_center);//Set Keep aspect ratio centeredImageView. Setlayoutparams(New Imageswitcher. Layoutparams(Layoutparams. WRAP_content, Layoutparams. WRAP_content));Return ImageView;}        });Galleryadapter adapter = new Galleryadapter (mainactivity. this, imageId);Gallery. Setadapter(adapter);Gallery. SetSelection(imageId. Length/2);Gallery. Setonitemselectedlistener(New Onitemselectedlistener () {@Override public void onitemselected (adapterview<?> parent, Vi EW view,int position, long id) {Imageswitcher. Setimageresource(Imageid[position]);} @Override public void onnothingselected (Adapterview<?> arg0) {}});}}

One of the adapters required:

ImportAndroid.content.Context;ImportAndroid.content.res.TypedArray;ImportAndroid.view.View;ImportAndroid.view.ViewGroup;ImportAndroid.widget.BaseAdapter;ImportAndroid.widget.Gallery;ImportAndroid.widget.ImageView; Public  class galleryadapter extends baseadapter {    Private int[] imageId;PrivateContext Mcontext;/** * Enter an array of context and picture resources * @param mcontext * @param imageId * *     Public Galleryadapter(Context Mcontext,int[] imageId) { This. Mcontext = Mcontext; This. imageId = ImageId; }@Override     Public int GetCount() {returnImageid.length; }@Override     PublicObjectGetItem(intPosition) {returnImageid[position]; }@Override     Public Long Getitemid(intPosition) {returnPosition }@Override     PublicViewGetView(intPosition, View Convertview, ViewGroup parent) {ImageView imageView1;if(Convertview = =NULL) {ImageView1 =NewImageView (Mcontext);            Imageview1.setscaletype (ImageView.ScaleType.FIT_XY); Imageview1.setlayoutparams (NewGallery.layoutparams ( the,135));            TypedArray TypedArray = mcontext. Obtainstyledattributes (R.styleable.gallery); Imageview1.setbackgroundresource (Typedarray.getresourceid (r.styleable.gallery_android_galleryitembackg Round0)); Imageview1.setpadding (5,0,5,0);//Set the inner margin of the ImageView}Else{imageView1 = (ImageView) Convertview; } imageview1.setimageresource (Imageid[position]);//Set the picture to be displayed for ImageView        returnImageView1;//Return to ImageView}}

To this ok!
