仿微信(网易的界面)

第一步: AndroidManifest.xml 的配置

     
         
          
      
          //定义了 一些样式        
                   
                        
                         
                     
                
           
      
     

　　样式

　　选择器selector_tabtext.xml  和tab_indicator.xml

     

       //selector_tabtext
         
          
          
          
      
     

     
       //tab_indicator    
          
               
          
      
     

 

第二步 :class MainActivity extends FragmentActivity

/**     * Tab标题     */    private static final String[] TITLE = new String[] { "头条", "房产", "另一面"                                                         };    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);                //ViewPager的adapter        FragmentPagerAdapter adapter = new TabPageIndicatorAdapter(getSupportFragmentManager());        ViewPager pager = (ViewPager)findViewById(R.id.pager);        pager.setAdapter(adapter);   //viewpage设置值        //实例化TabPageIndicator然后设置ViewPager与之关联        TabPageIndicator indicator = (TabPageIndicator)findViewById(R.id.indicator);        indicator.setViewPager(pager);  //下标 绑定 page                //如果我们要对ViewPager设置监听，用indicator设置就行了        indicator.setOnPageChangeListener(new OnPageChangeListener() {                        @Override            public void onPageSelected(int arg0) {                Toast.makeText(getApplicationContext(), TITLE[arg0], Toast.LENGTH_SHORT).show();            }                        @Override            public void onPageScrolled(int arg0, float arg1, int arg2) {                            }                        @Override            public void onPageScrollStateChanged(int arg0) {                            }        });            }        /**     * ViewPager适配器     * @author len     *     */    class TabPageIndicatorAdapter extends FragmentPagerAdapter {        public TabPageIndicatorAdapter(FragmentManager fm) {            super(fm);        }        @Override        public Fragment getItem(int position) {            //新建一个Fragment来展示ViewPager item的内容，并传递参数            Fragment fragment = new  ItemFragment();              Bundle args = new Bundle();              args.putString("arg", TITLE[position]);              fragment.setArguments(args);                          return fragment;        }        @Override        public CharSequence getPageTitle(int position) {            return TITLE[position%TITLE.length ];   // 取数组里面的值 最为title        }        @Override        public int getCount() {            return TITLE.length;        }    }

Fragment

public class ItemFragment extends Fragment {    @Override    public View onCreateView(LayoutInflater inflater, ViewGroup container,            Bundle savedInstanceState) {                View contextView = inflater.inflate(R.layout.fragment_item, container, false);                       TextView mTextView = (TextView) contextView.findViewById(R.id.textview);                //获取Activity传递过来的参数        Bundle mBundle = getArguments();        String title = mBundle.getString("arg");        mTextView.setText(title);            return contextView;    }    @Override    public void onActivityCreated(Bundle savedInstanceState) {        super.onActivityCreated(savedInstanceState);    }}
