首先在引導(dǎo)界面的布局文件定義一個(gè)ViewPager：

  <android.support.v4.view.ViewPager
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:id="@+id/vp"
  android:persistentDrawingCache="animation"/>

再定義幾個(gè)ImageView來顯示不同的圖片：
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:id="@+id/ll"
android:layout_alignParentBottom="true"
android:orientation="horizontal"
android:gravity="center_horizontal">

  <ImageView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/iv1"
      android:src="@drawable/login_point" />

  <ImageView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/iv2"
      android:src="@drawable/login_point" />

  <ImageView
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:id="@+id/iv3"
      android:src="@drawable/login_point" />

  </LinearLayout>

設(shè)置ViewPager的Adapter捺僻，繼承自PagerAdapter：

  public class MyAdapter extends PagerAdapter {
      private List<View> views;
      private Context context;
      public MyAdapter(List<View> views,Context context){
          this.views=views;
          this.context=context;
      }

  @Override
  public void destroyItem(ViewGroup container, int position, Object object) {
      container.removeView(views.get(position));
  }

  @Override
  public Object instantiateItem(ViewGroup container, int position) {
      container.addView(views.get(position));
      return views.get(position);
  }

  @Override
  public int getCount() {
      return views.size();
  }

  @Override
  public boolean isViewFromObject(View view, Object object) {
      return (view==object);
      }
  }

最后在onCreate方法中設(shè)置Adapter：

  adapter=new MyAdapter(views,this);
  vp= (ViewPager) findViewById(R.id.vp);
  vp.setAdapter(adapter);

在每個(gè)圖片下面添加導(dǎo)航點(diǎn)，這就需要調(diào)用ViewPager的setOnPageChangeListener(this)方法了桩卵。并覆蓋onPageSelected(int position)忧陪。

  @Override
  public void onPageSelected(int position) {
      for (int i = 0; i < ids.length; i++) {
      //被選中的頁面的導(dǎo)航點(diǎn)顏色要更深一些
          if (position == i) {
              dots[i].setImageResource(R.drawable.login_point_selected);
          } else {
              dots[i].setImageResource(R.drawable.login_point);
          }
      }
  }

第一次啟動(dòng)應(yīng)用是啟動(dòng)歡迎界面，在啟動(dòng)引導(dǎo)界面，最后啟動(dòng)主界面售担，第二次后就不啟動(dòng)引導(dǎo)界面了，通過Handler來發(fā)送消息署辉。

  public static final int time=2000;
  public static final int GOHMOE =1000;
  public static final int GOGUILD =1001;

  private boolean isFistIn=false;

  private Handler mHandler=new Handler(){
      @Override
      public void handleMessage(Message msg) {
          switch (msg.what){
              case GOHMOE:
                  goHome();
                  break;
              case GOGUILD:
                  goGuild();
                  break;
          }
      }
  };
  
  private void goHome(){
  Intent intent=new Intent(WelcomAty.this,MainActivity.class);
  startActivity(intent);
  finish();
  }private void goGuild(){
  Intent intent=new Intent(WelcomAty.this,Guild.class);
  startActivity(intent);
  finish();
  }

  private void init(){
  SharedPreferences preferences= getSharedPreferences("jike",MODE_PRIVATE);
  isFistIn=preferences.getBoolean("isFistIn",true);
  if (!isFistIn){
      mHandler.sendEmptyMessageDelayed(GOHMOE,time);
  }else {

  mHandler.sendEmptyMessageDelayed(GOGUILD,time);
      SharedPreferences.Editor editor=preferences.edit();
      editor.putBoolean("isFistIn",false);
      editor.commit();
      }
  }
