界面布局(三)

xml的布局文件弄好了，我们就要给几个button设置点击事件。

1.点击跳转，那我们需要给他设置跳转页

2.如何把几个子类添加到ViewPager

2.绑定Click事件

建一个基类BasePager,让五个类去继承它。

</pre><pre name="code" class="java">public class BasePager { public Activity mActivity; public View mRootView;//当前页面的布局对象 public BasePager(Activity activity) { mActivity = activity; mRootView = initView(); } public View initView() { View view = View.inflate(mActivity, R.layout.base_pager, null); return view; } 其中一个子类

public class HomePager extends BasePager { public HomePager(Activity activity) { super(activity); // TODO Auto-generated constructor stub } public void initData(){ } }

viewpager,绑定RadioGroup click监听事件

public class ContentFragment extends BaseFragment { private NoScrollViewPager mViewPager; private RadioGroup rgGroup; private ArrayList<BasePager> mPagers; //初始化数据 public View initView() { View view = View.inflate(mactivity, R.layout.fragment_content, null); mViewPager = (NoScrollViewPager) view.findViewById(R.id.vp_content); rgGroup = (RadioGroup) view.findViewById(R.id.rg_group); return view; } //将五个子类添加到Viewpager public void initData() { mPagers = new ArrayList<BasePager>(); mPagers.add(new HomePager(mactivity)); mPagers.add(new NewCenterPager(mactivity)); mPagers.add(new GovAffairsPager(mactivity)); mPagers.add(new SmartServicePager(mactivity)); mPagers.add(new SettingPager(mactivity)); mViewPager.setAdapter(new ContentAdapter()); // RadioGroup监听事件 rgGroup.setOnCheckedChangeListener(new OnCheckedChangeListener() { public void onCheckedChanged(RadioGroup group, int checkedId) { switch (checkedId) { case R.id.rb_home: mViewPager.setCurrentItem(0, false); break; case R.id.rb_news: mViewPager.setCurrentItem(1, false); break; case R.id.rb_smart: mViewPager.setCurrentItem(2, false); break; case R.id.rb_gov: mViewPager.setCurrentItem(3, false); break; case R.id.rb_setting: mViewPager.setCurrentItem(4, false); break; default: break; } } }); class ContentAdapter extends PagerAdapter { @Override public int getCount() { // TODO Auto-generated method stub return mPagers.size(); } @Override public boolean isViewFromObject(View arg0, Object arg1) { // TODO Auto-generated method stub return arg0 == arg1; } // 初始化item布局 public Object instantiateItem(ViewGroup container, int position) { BasePager pager = mPagers.get(position); View view = pager.mRootView; //pager.initData(); , 初始化item，默认会加载下一个页面，为了节省流量和性能，对其优化 container.addView(view); return view; } @Override public void destroyItem(ViewGroup container, int position, Object object) { container.removeView((View) object); } } }
