Android ViewPager实现左右滑动的实例

Android ViewPager实现左右滑动的实例

多个标题以及标题下的每个View视图

<com.shizhefei.view.indicator.ScrollIndicatorView
   android:id="@+id/moretab_indicator"
   android:layout_width="match_parent"
   android:layout_height="45dp" />
 <View
   android:layout_width="match_parent"
   android:layout_height="0.5dp"
   android:background="#f2f2f2"
   />
 <android.support.v4.view.ViewPager
   android:id="@+id/moretab_viewPager"
   android:layout_width="match_parent"
   android:layout_height="match_parent" />

在build.gradle添加包：

//左右滑动布局框架
 compile 'com.shizhefei:ViewPagerIndicator:1.1.4' 

然后在代码中实现功能：

ScrollIndicatorView scrollIndicatorView;
  ViewPager viewPager;
  private String[] titles = {"在线申办", "信用卡代换", "信用卡取现", "办卡进度"};
  private IndicatorViewPager indicatorViewPager;
  private LayoutInflater inflate;
  private Context mContext; 

 private void initViewPager() {
//    默认字体是14
    float unSelectSize = 14;
//    滑动字体是14*1.2f
    float selectSize = unSelectSize;
    scrollIndicatorView.setOnTransitionListener(new OnTransitionTextListener().setColor(0xFF1DA9FF, Color.GRAY).setSize(selectSize, unSelectSize));
    scrollIndicatorView.setScrollBar(new ColorBar(mContext, 0xFF1DA9FF, 2)); 

    viewPager.setOffscreenPageLimit(1);
    indicatorViewPager = new IndicatorViewPager(scrollIndicatorView, viewPager);
    inflate = LayoutInflater.from(mContext);
    indicatorViewPager.setAdapter(new MyAdapter(getFragmentManager()));
  } 

  private int size = titles.length; 

  private class MyAdapter extends IndicatorViewPager.IndicatorFragmentPagerAdapter { 

    public MyAdapter(FragmentManager fragmentManager) {
      super(fragmentManager);
    } 

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

    @Override
    public View getViewForTab(int position, View convertView, ViewGroup container) {
      if (convertView == null) {
        convertView = inflate.inflate(R.layout.tab_top, container, false);
      }
      TextView textView = (TextView) convertView;
      textView.setText(titles[position % titles.length]);
      int padding = dipToPix(10);
      textView.setPadding(padding, 0, padding, 0);
      return convertView;
    } 

    @Override
    public Fragment getFragmentForPage(int position) {
      CreditCardFragment fragment = new CreditCardFragment();
      /* Bundle bundle = new Bundle();
      bundle.putInt(MoreFragment.INTENT_INT_INDEX, position);
      fragment.setArguments(bundle);*/
      return fragment; 

//      MoreFragment fragment = new MoreFragment();
//      Bundle bundle = new Bundle();
//      bundle.putInt(MoreFragment.INTENT_INT_INDEX, position);
//      fragment.setArguments(bundle);
//      return fragment;
    } 

    @Override
    public int getItemPosition(Object object) {
      //这是ViewPager适配器的特点,有两个值 POSITION_NONE，POSITION_UNCHANGED，默认就是POSITION_UNCHANGED,
      // 表示数据没变化不用更新.notifyDataChange的时候重新调用getViewForPage
      return PagerAdapter.POSITION_NONE;
    } 

  } 

  private int dipToPix(float dip) {
    int size = (int) TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, dip, getResources().getDisplayMetrics());
    return size;
  }
