[android] 练习viewpagerindicator的使用(二)详解手机开发

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>
