TabLayout +ViewPager

总结和问题

一实现看清楚是activity中嵌套fragment还是fragment中嵌套fragment
二具体的xml的配置信息

一.导入包

com.android.support:design:24.2.1

二.代码

1.xml

<android.support.design.widget.TabLayout        android:id="@+id/tablayout_tabtwo"        android:layout_width="match_parent"        android:layout_height="40dp"        //选择前字体的颜色        app:tabTextColor="@color/block"          //被选择后字体的颜色app:tabSelectedTextColor="@color/me_biaoti_background"          //导航条的颜色        app:tabIndicatorColor="@color/me_biaoti_background"         //导航条的宽度        app:tabIndicatorHeight="3dp"        /**        *下面的两个配置属性 ：当一行的字体太多时，你在配置文件中设置的字体大小不起作用，因为他有默认的间距，所以要去重新设置他们        **/        app:tabPaddingStart="3dp"        app:tabPaddingEnd="3dp"        app:tabTextAppearance="@style/MyCustomTabTextAppearanceone">    </android.support.design.widget.TabLayout>    <android.support.v4.view.ViewPager        android:id="@+id/view_pagertwo"        android:layout_width="match_parent"        android:layout_height="0dp"        android:layout_weight="1"></android.support.v4.view.ViewPager>

style

<style name="MyCustomTabTextAppearanceone" parent="TextAppearance.Design.Tab">        <item name="android:textSize">17sp</item>        <item name="textAllCaps">false</item>    </style>

2.activity
public class XcdxqtwoActivity extends FragmentActivity{
private TabLayout mTabLayout;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_xcdxqtwo);
initView();
initData();
}
private void initView() {
mTabLayout = (TabLayout) findViewById(R.id.tablayout_tabtwo);
mViewPager = (ViewPager) findViewById(R.id.view_pagertwo);
}

private void initData() {    String [] titles = {"风险信息","标准检查","隐患整改","巡查记录"};    List<Fragment> mList = new ArrayList<Fragment>();    mList.add(new XcdxqtwoFragment());    mList.add(new XcdxqtwoFragment());    mList.add(new XcdxqtwoFragment());    mList.add(new XcdxqtwoFragment());    // getSupportFragmentManager()支持v4包。这个是activity中嵌套fragment，如果是fragment中嵌套fragment为getChildFragmentManager（）    XcdxqtwoAdapter adapter = new XcdxqtwoAdapter(getSupportFragmentManager(),XcdxqtwoActivity.this,titles,mList);    mViewPager.setAdapter(adapter);    mTabLayout.setupWithViewPager(mViewPager);    mTabLayout.setTag(titles);}

}

3.adapter

public class XcdxqtwoAdapter extends FragmentPagerAdapter {    private  String[] titles;    private Context context;    private List<Fragment> fragments;    public XcdxqtwoAdapter(FragmentManager fm,Context context,String[] titles,List<Fragment> fragments) {        super(fm);        this.context = context;        this.titles = titles;        this.fragments = fragments;    }    @Override    public Fragment getItem(int position) {        return fragments.get(position);    }    @Override    public int getCount() {        return fragments.size();    }    @Override    public CharSequence getPageTitle(int position) {        return titles[position];    }}
