Android仿腾讯视频广告图片轮播效果代码

本例子是利用Gallery制作的一个图片轮播的例子、要想使用ViewPager的哥们可以绕道了、仿腾讯视频的最新视频信息的轮播显示、点击时可跳转、能无限循环自动滑动和手动滑动、动画切换流畅、有少量注释、编译版本2.3.3（高版本上依然可以正常运行的、没有任何问题）、编码GBK、效果图如下

XML代码

<FrameLayout
	android:layout_width="fill_parent"
	android:layout_height="257dip" >

	<com.demo.MyGallery
		android:id="@ id/banner_gallery"
		android:layout_width="fill_parent"
		android:layout_height="257dip"
		android:background="#000"
		android:fadingEdgeLength="0.0dp"
		android:keepScreenOn="true"
		android:soundEffectsEnabled="false" />

	<LinearLayout
		android:id="@ id/ll_bottomNavPoint"
		android:layout_width="fill_parent"
		android:layout_height="wrap_content"
		android:layout_gravity="bottom|center"
		android:background="#00000000"
		android:gravity="center"
		android:orientation="vertical"
		android:paddingBottom="5dp" >

		<LinearLayout
			android:id="@ id/ll_focus_indicator_container"
			android:layout_width="fill_parent"
			android:layout_height="wrap_content"
			android:gravity="center"
			android:orientation="horizontal" />
	</LinearLayout>
</FrameLayout>

Java代码onCreate

public void onCreate(Bundle savedInstanceState) {
	super.onCreate(savedInstanceState);
	setContentView(R.layout.main);
	InitImgList();
	ll_focus_indicator_container = (LinearLayout) findViewById(R
		.id.ll_focus_indicator_container);
	InitFocusIndicatorContainer();
	gallery = (MyGallery) findViewById(R.id.banner_gallery);
	gallery.setAdapter(new ImageAdapter(this));
	gallery.setFocusable(true);
	gallery.setOnItemSelectedListener(new OnItemSelectedListener() {

		public void onItemSelected(AdapterView<?> arg0, View arg1,
				int selIndex, long arg3) {
			// 修改上一次选中项的背景
			selIndex = selIndex % imgList.size();

			ImageView preSelImg = (ImageView) ll_focus_indicator_container
					.findViewById(preSelImgIndex);
			preSelImg.setImageDrawable(MainActivity.this.getResources()
					.getDrawable(R.drawable.ic_focus));
			// 修改当前选中项的背景
			ImageView curSelImg = (ImageView) ll_focus_indicator_container
					.findViewById(selIndex);
			curSelImg.setImageDrawable(MainActivity.this.getResources()
					.getDrawable(R.drawable.ic_focus_select));
			preSelImgIndex = selIndex;
		}

		public void onNothingSelected(AdapterView<?> arg0) {
		}
	});

	Log.i("msg", "260px:"   px2dip(this, 260));
}

最后给贴上Demo的源代码、希望对大家有用、有兴趣的哥们可以下载看看
