Question

使用Android Framgent，我有三个片段布局我想在flag的基础上隐藏片段。当第一个片段可见时想要禁用第二个片段我成功地隐藏了标签布局的标题标题，但无法删除Page。如何实现它。我已经搜索了很多，但是我没有接受。

public class Sample extends AppCompatActivity implements Commands.FragmentDataListener_Commands_epg{
Bundle dataBundle;
TabLayout tabLayout;
String flag;
private Sample.SectionsPagerAdapter mSectionsPagerAdapter;
private ViewPager mViewPager;
private GoogleApiClient client;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_details_customer);

    Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
    setSupportActionBar(toolbar);

    Intent intent=getIntent();
    flag = intent.getStringExtra("flag");

    mSectionsPagerAdapter = new Sample.SectionsPagerAdapter(getSupportFragmentManager());
    mViewPager = (ViewPager) findViewById(R.id.container);
    mViewPager.setAdapter(mSectionsPagerAdapter);

    tabLayout = (TabLayout) findViewById(R.id.tabs);
    tabLayout.setupWithViewPager(mViewPager);
    if(flag.equals("1")) {
        tabLayout.removeTabAt(0);

    }
    else if(flag.equals("2"))
    {
        tabLayout.removeTabAt(1);
    }

    client = new GoogleApiClient.Builder(this).addApi(AppIndex.API).build();

}


@Override
public void onFragmentDataUpdated(Bundle dataBundle)
{
    this.dataBundle=dataBundle;
}

@Override
public void onStart() {
    super.onStart();

    client.connect();
    AppIndex.AppIndexApi.start(client, getIndexApiAction());
}

@Override
public void onStop() {
    super.onStop();

    AppIndex.AppIndexApi.end(client, getIndexApiAction());
    client.disconnect();
}
public class SectionsPagerAdapter extends FragmentPagerAdapter {

    public SectionsPagerAdapter(FragmentManager fm) {
        super(fm);
    }

    @Override
    public Fragment getItem(int position) {
        switch (position) {
            case 0:
                    //first page
            case 1:
                    //second page
        }
        return null;
    }

    @Override
    public int getCount() {
        // Show 2 total pages.
            return 2;
    }

    @Override
    public CharSequence getPageTitle(int position) {
        switch (position) {
            case 0:
                return "First";
            case 1:
                return "second";
          }
        return null;
    }
}}

提前谢谢。

由于您在意图中获得了旗帜，因此您不需要tabLayout。只需初始化和片段到您的视图。一些代码如下：

Fragment fragmentInput = new  FragmentAddVehicle();
FragmentManager  getSupportFragmentManager.beginTransaction().add(R.id.ll_root_container, fragmentInput).commit();

隐藏Android片段
