一：布局
<?xml version="1.0" encoding="utf-8"?> <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:orientation="vertical" > <android.support.v4.view.ViewPager android:id="@+id/whatsnew_viewpager" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_gravity="center" > <android.support.v4.view.PagerTitleStrip android:id="@+id/pagertitle" android:layout_width="wrap_content" android:layout_height="0dp" android:layout_gravity="bottom" android:background="#0000" android:textColor="#ffff" /> </android.support.v4.view.ViewPager> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="horizontal" > <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_gravity="bottom" android:layout_marginBottom="30dp" android:gravity="center_horizontal" > <ImageView android:id="@+id/page0" android:layout_width="wrap_content" android:layout_height="wrap_content" android:scaleType="matrix" android:src="@drawable/page_now" /> <ImageView android:id="@+id/page1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page3" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page4" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> <ImageView android:id="@+id/page5" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginLeft="10dp" android:scaleType="matrix" android:src="@drawable/page" /> </LinearLayout> </LinearLayout> </FrameLayout>
二：Activity
public class Whatsnew extends Activity { private ViewPager mViewPager; private ImageView mPage0; private ImageView mPage1; private ImageView mPage2; private ImageView mPage3; private ImageView mPage4; private ImageView mPage5; private int currIndex = 0; private Context mCon; private PagerAdapter adapter; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.whatsnew_viewpager); mCon = Whatsnew.this; initView(); initData(); registerListener(); } private void initView(){ mViewPager = (ViewPager) findViewById(R.id.whatsnew_viewpager); mPage0 = (ImageView)findViewById(R.id.page0); mPage1 = (ImageView)findViewById(R.id.page1); mPage2 = (ImageView)findViewById(R.id.page2); mPage3 = (ImageView)findViewById(R.id.page3); mPage4 = (ImageView)findViewById(R.id.page4); mPage5 = (ImageView)findViewById(R.id.page5); } private void initData(){ final ArrayList<View> list = new ArrayList<View>(); //通过布局加载器获取到布局 LayoutInflater mLi = LayoutInflater.from(mCon); View view1 = mLi.inflate(R.layout.whats1, null); View view2 = mLi.inflate(R.layout.whats2, null); View view3 = mLi.inflate(R.layout.whats3, null); View view4 = mLi.inflate(R.layout.whats4, null); View view5 = mLi.inflate(R.layout.whats5, null); View view6 = mLi.inflate(R.layout.whats6, null); list.add(view1); list.add(view2); list.add(view3); list.add(view4); list.add(view5); list.add(view6); adapter = new PagerAdapter() { @Override public boolean isViewFromObject(View arg0, Object arg1) { return arg0 == arg1; } @Override public int getCount() { return list.size(); } @Override public void destroyItem(View container, int position, Object object) { ((ViewPager)container).removeView(list.get(position)); } @Override public Object instantiateItem(View container, int position) { ((ViewPager)container).addView(list.get(position)); return list.get(position); } @Override public void finishUpdate(View arg0) { // TODO Auto-generated method stub } @Override public void restoreState(Parcelable arg0, ClassLoader arg1) { // TODO Auto-generated method stub } @Override public Parcelable saveState() { // TODO Auto-generated method stub return null; } @Override public void startUpdate(View arg0) { // TODO Auto-generated method stub } }; } private void registerListener(){ mViewPager.setOnPageChangeListener(new MyOnPageChangeListener()); mViewPager.setAdapter(adapter); } public class MyOnPageChangeListener implements OnPageChangeListener{ @Override public void onPageScrollStateChanged(int arg0) { } @Override public void onPageScrolled(int arg0, float arg1, int arg2) { } @Override public void onPageSelected(int arg0) { switch (arg0) { case 0: mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 1: mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage0.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 2: mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage1.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 3: mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage2.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 4: mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage3.setImageDrawable(getResources().getDrawable(R.drawable.page)); mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; case 5: mPage5.setImageDrawable(getResources().getDrawable(R.drawable.page_now)); mPage4.setImageDrawable(getResources().getDrawable(R.drawable.page)); break; } currIndex = arg0; } } public void startbutton(View v) { Intent intent = new Intent(); intent.setClass(Whatsnew.this,WhatsnewDoor.class); startActivity(intent); this.finish(); } }
