第六篇 Gallery与ImageSwitcher混合使用

直奔主题~！

结构如图:

main.xml代码：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:orientation="vertical" android:layout_width="fill_parent"android:layout_height="fill_parent" android:gravity="center"><ImageSwitcher android:id="@+id/is"android:layout_width="300dip" android:layout_height="300dip"></ImageSwitcher><Gallery android:layout_width="fill_parent" android:id="@+id/gl"android:layout_height="wrap_content" android:spacing="5dip"></Gallery></LinearLayout>

Control_Gallery_ImageSwitcher .java代码:

public class Control_Gallery_ImageSwitcherActivity extends Activity {private ImageSwitcher is;private Gallery gl;int[] imggroup;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        findAll();        bind();    }        public void findAll()    {    is=(ImageSwitcher) this.findViewById(R.id.is);      gl=(Gallery) this.findViewById(R.id.gl);    imggroup=new int[]{R.raw.jwc1,R.raw.jwc2,R.raw.jwc3,R.raw.jwc4,R.raw.jwc5};    }        public void bind()    {    is.setFactory(new ViewFactory() {public View makeView() {// TODO Auto-generated method stub//return null;ImageView iv=new ImageView(Control_Gallery_ImageSwitcherActivity.this);iv.setLayoutParams(new  ImageSwitcher.LayoutParams(100, 100));return iv;}});    is.setAnimation(AnimationUtils.loadAnimation(Control_Gallery_ImageSwitcherActivity.this, android.R.anim.fade_in));    is.setAnimation(AnimationUtils.loadAnimation(Control_Gallery_ImageSwitcherActivity.this, android.R.anim.fade_out));        is.setBackgroundResource(imggroup[0]);        gl.setAdapter(new myadpter(Control_Gallery_ImageSwitcherActivity.this));        gl.setOnItemClickListener(new OnItemClickListener() {public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {// TODO Auto-generated method stubis.setBackgroundResource(imggroup[arg2]);}});            }        class myadpter extends BaseAdapter    {    Context ct;        public myadpter(Context ct)    {    this.ct=ct;    }public int getCount() {// TODO Auto-generated method stubreturn imggroup.length;}public Object getItem(int position) {// TODO Auto-generated method stubreturn position;}public long getItemId(int position) {// TODO Auto-generated method stubreturn position;}public View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stub//return null;    ImageView iv=new ImageView(ct);    iv.setImageBitmap(BitmapFactory.decodeResource(getResources(), imggroup[position])) ;    iv.setLayoutParams(new Gallery.LayoutParams(80, 80));return iv;}        }}
