[android] 练习viewpagerindicator的使用（二）

主要还是想实现滑动的tab切换效果

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

 */
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>
