MainActivity.java

package com.example.csdn;import com.viewpagerindicator.TabPageIndicator;import android.os.Bundle;import android.support.v4.app.Fragment;import android.support.v4.app.FragmentActivity;import android.support.v4.app.FragmentManager;import android.support.v4.app.FragmentPagerAdapter;import android.support.v4.view.ViewPager;import android.view.LayoutInflater;import android.view.View;import android.view.ViewGroup;import android.widget.TextView;public class MainActivity extends FragmentActivity {  private TabPageIndicator tpi_tab;  private ViewPager vp_content;  @Override  protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    setContentView(R.layout.activity_main);    tpi_tab = (TabPageIndicator) findViewById(R.id.vpi_tab);    vp_content = (ViewPager) findViewById(R.id.vp_content);    FragmentManager fm = getSupportFragmentManager();    TabAdapter adapter = new TabAdapter(fm);    // ViewPager设置适配器    vp_content.setAdapter(adapter);    // 指示器绑定ViewPager    tpi_tab.setViewPager(vp_content, 0);  }}/** * 标签部分适配器 * * @author taoshihan * */class TabAdapter extends FragmentPagerAdapter {  public static final String[] TITLES = new String[] { "业界", "移动", "研发","PHP","Android","Java","前端" };  public TabAdapter(FragmentManager fm) {    super(fm);  }  @Override  public Fragment getItem(int arg0) {    return new ContentFragment(arg0);  }  @Override  public int getCount() {    return TITLES.length;  }  @Override  public CharSequence getPageTitle(int position) {    // TODO Auto-generated method stub    return TITLES[position % TITLES.length];  }}/** * 内容部分 * @author taoshihan * */class ContentFragment extends Fragment{  private int index;  public ContentFragment(int index) {    this.index=index;  }  @Override  public View onCreateView(LayoutInflater inflater, ViewGroup container,      Bundle savedInstanceState) {    View view=View.inflate(getActivity(), R.layout.main_content, null);    TextView tv_content=(TextView) view.findViewById(R.id.tv_content);    String[] titles=TabAdapter.TITLES;    tv_content.setText(titles[index]);    return view;  }}

样式就是在清单文件中给activity填上主题

<activity      android:name=".MainActivity"      android:label="@string/app_name"       android:theme="@style/Theme.PageIndicatorDefaults">      <intent-filter>        <action android:name="android.intent.action.MAIN" />        <category android:name="android.intent.category.LAUNCHER" />      </intent-filter>    </activity>
