tab页布局

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical" >
    <WebView 
        android:layout_height="match_parent"
        android:layout_width="match_parent"
        android:id="@+id/web1"/>
</LinearLayout>

获取ViewPager

mPager = (ViewPager) findViewById(R.id.viewpager);

获取每个tab加入数组

　　　　 LayoutInflater inflater=LayoutInflater.from(this);
        View tab1= inflater.inflate(R.layout.tab1, null);
        View tab2= inflater.inflate(R.layout.tab2, null);
        View tab3= inflater.inflate(R.layout.tab3, null);
        View tab4= inflater.inflate(R.layout.tab4, null);
        mView.add(tab1);
        mView.add(tab2);
        mView.add(tab3);
        mView.add(tab4);

 

设置ViewPager的适配器

　　　　　　 adapter=new PagerAdapter() {
            @Override
            public boolean isViewFromObject(View arg0, Object arg1) {
                
                return arg0==arg1;
            }
            
            @Override
            public void destroyItem(ViewGroup container, int position,
                    Object object) {
                container.removeView(mView.get(position));
            }
            @Override
            public Object instantiateItem(ViewGroup container, int position) {
                View view=mView.get(position);
                container.addView(view);
                return view;
            }

            @Override
            public int getCount() {
                return mView.size();
                
            }
        };
        mPager.setAdapter(adapter);
