找了许多实现该功能的例子,但效果都不很理想,于是自己结合网上的资源及自己的总结,整理了一下,发出来,供大家参考。这个是自己做的,仿优酷客户端的。
先看效果:
****************************************************************************
1.创建项目
2.设置界面layout
主界面:activity_main.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:umadsdk="http://schemas.android.com/apk/res/com.LoveBus" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <ImageView android:layout_width="fill_parent" android:layout_height="wrap_content" android:src="@drawable/title" /> <RelativeLayout android:id="@+id/linearLayout1" android:layout_width="fill_parent" android:layout_height="40dip" android:background="#FFFFFF" android:orientation="vertical" > <LinearLayout android:id="@+id/tabText" android:layout_marginTop="10dp" android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <TextView android:id="@+id/text1" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1.0" android:gravity="center" android:text="个人中心" android:textColor="#000000" android:textSize="14sp" /> <TextView android:id="@+id/text2" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1.0" android:gravity="center" android:text="优酷首页" android:textColor="#000000" android:textSize="14sp" /> <TextView android:id="@+id/text3" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1.0" android:gravity="center" android:text="频道列表" android:textColor="#000000" android:textSize="14sp" /> </LinearLayout> <ImageView android:id="@+id/cursor" android:layout_width="fill_parent" android:layout_height="wrap_content" android:scaleType="matrix" android:layout_alignParentBottom="true" android:src="@drawable/slide" /> </RelativeLayout> <android.support.v4.view.ViewPager android:id="@+id/vPager" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" android:layout_weight="1.0" android:background="#000000" android:flipInterval="30" android:persistentDrawingCache="animation" /> </LinearLayout>
3.设置各标签所对应的界面
频道列表:channel_layout.xml
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <ImageView android:layout_width="fill_parent" android:layout_height="fill_parent" android:src="@drawable/lay3" /> </LinearLayout>
优酷首页:home_layout.xml
个人中心:personal_layout.xml
这两个页面跟频道列表一样,换张图片即可
3.界面做好之后,就是主程序了
MainActivity.java

} @Override public void restoreState(Parcelable arg0, ClassLoader arg1) { } @Override public Parcelable saveState() { return null; } @Override public void startUpdate(View arg0) { } } /** * 初始化动画 */ private void InitImageView() { //获取滑块儿控件 slideImage=(ImageView) findViewById(R.id.cursor);

//如果滑块儿图片宽度超过每个tab的宽度时,将滑块儿宽度设置为与tab宽度相同 if (ivCursorWidth >= tabWidth) { slideImage.getLayoutParams().width = tabWidth; ivCursorWidth = tabWidth; fromX=0; }else{ fromX = (tabWidth - ivCursorWidth) / 2; } // 设置动画初始位置 Matrix matrix = new Matrix(); matrix.postTranslate( fromX+tabWidth, 0); slideImage.setImageMatrix(matrix); } /** * 页面切换监听 */ public class MyOnPageChangeListener implements OnPageChangeListener { @Override public void onPageSelected(int arg0) { //设置页面切换时动画偏移量 Animation animation = new TranslateAnimation(tabWidth * currIndex-tabWidth, tabWidth * arg0-tabWidth, 0, 0); currIndex = arg0; animation.setFillAfter(true);//图片停在动画结束位置 animation.setDuration(0);//设置动画移动毫秒数 slideImage.startAnimation(animation); } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageScrollStateChanged(int arg0) { } } private void showDialog(String title,String msg){ AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setIcon(android.R.drawable.ic_dialog_info); builder.setTitle(title); builder.setMessage(msg); builder.setPositiveButton("确定", null); builder.create().show(); } }
其中的图片大家可以自行下载,实现效果就行,还有看到很多同学再问如何给viewpaper中的每个view设置监听,在这里告诉大家一下,设置监听需要在listViews.add()之前获得控件并监听,之后再添加,否则不起作用,如本程序中隐去的btn监听。
