Переход фрагмента Android ⇐ Android

[Anonymous]

У меня есть три фрагмента: F1, F2 и F3. < /p>

В случае перехода от F1 к F2 и возвращаться к F1, F1 Oncreateview () не называется. < /p>

Но в случае F1 Traningsition и возвращается к F1, F1's at on't on't on't on't on't on't on on on ecrate. Это означает, что макет F1 завывает новую макет.public class MainActivity extends AppCompatActivity {

private Toolbar toolbar;
private TabLayout tabLayout;
private ViewPager viewPager;

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);

getSupportActionBar().setDisplayHomeAsUpEnabled(true);

viewPager = (ViewPager) findViewById(R.id.viewpager);
setupViewPager(viewPager);

tabLayout = (TabLayout) findViewById(R.id.tabs);
tabLayout.setupWithViewPager(viewPager);

}

private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
adapter.addFragment(new F1(), "Raw Data");
adapter.addFragment(new F2(), "Grip");
adapter.addFragment(new F3(), "Press");
viewPager.setAdapter(adapter);
}

class ViewPagerAdapter extends FragmentPagerAdapter {
private final List mFragmentList = new ArrayList();
private final List mFragmentTitleList = new ArrayList();

public ViewPagerAdapter(FragmentManager manager) {
super(manager);
}

@Override
public Fragment getItem(int position) {
return mFragmentList.get(position);
}

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

public void addFragment(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}

@Override
public CharSequence getPageTitle(int position) {

return mFragmentTitleList.get(position);
}
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();

//noinspection SimplifiableIfStatement
if (id == R.id.action_settings) {
return true;
}

return super.onOptionsItemSelected(item);
}
}
