I have an activity that contains two fragments inside the presentation pager. I used the same layout to inflate these fragments. The layout has two editing texts located inside the linear layout, which is inside the relative layout. The problem is that when I switch from fragment A to fragment B, it first edits the text with focus in fragment A, and when I return from fragment B to fragment A, instead of the first editing text that has focus, the second editing text gets focus. How to solve it. I provide layouts and source code below. I do not return code inside fragment classes.
Activity:
public class LoginActivity extends BaseActivity {
public static final String selectedTabPosition = "selectedTabPosition";
private static String TAB_1_TAG = "Email";
private static String TAB_2_TAG = "Mobile";
private TabLayout mTabLayout;
private ViewPager mViewPager;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
TAB_1_TAG = getResources().getString(R.string.tab_email);
TAB_2_TAG = getResources().getString(R.string.tab_mobile);
mViewPager = (ViewPager) findViewById(R.id.viewpager);
mTabLayout = (TabLayout) findViewById(R.id.tabs);
setupViewPager(mViewPager);
mTabLayout.setupWithViewPager(mViewPager);
setupTabIcons();
mViewPager.setOnPageChangeListener(new ViewPager.OnPageChangeListener() {
@Override
public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) {
}
@Override
public void onPageSelected(int position) {
dismissKeyboard(mViewPager);
}
@Override
public void onPageScrollStateChanged(int state) {
}
});
}
private void setupTabIcons() {
LinearLayout tabOne = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.tab_custom, null);
TextView tvIconOne = (TextView) tabOne.findViewById(R.id.tv_tab_title);
tvIconOne.setText(TAB_1_TAG);
mTabLayout.getTabAt(0).setCustomView(tabOne);
setTypeface(tvIconOne, CustomFonts.Prime_regular);
mTabLayout.getTabAt(0).getCustomView().setSelected(true);
LinearLayout tabTwo = (LinearLayout) LayoutInflater.from(this).inflate(R.layout.tab_custom, null);
TextView tvIconTwo = (TextView) tabTwo.findViewById(R.id.tv_tab_title);
tvIconTwo.setText(TAB_2_TAG);
setTypeface(tvIconTwo, CustomFonts.Prime_regular);
mTabLayout.getTabAt(1).setCustomView(tabTwo);
}
private void setupViewPager(ViewPager viewPager) {
ViewPagerAdapter adapter = new ViewPagerAdapter(getSupportFragmentManager());
LoginFragment loginFragmentEmail = new LoginFragment();
Bundle emailBundle = new Bundle();
emailBundle.putInt(selectedTabPosition, 0);
loginFragmentEmail.setArguments(emailBundle);
LoginFragment loginFragmentMobile = new LoginFragment();
Bundle phoneBundle = new Bundle();
phoneBundle.putInt(selectedTabPosition, 1);
loginFragmentMobile.setArguments(phoneBundle);
adapter.addFrag(loginFragmentEmail, TAB_1_TAG);
adapter.addFrag(loginFragmentMobile, TAB_2_TAG);
viewPager.setAdapter(adapter);
}
class ViewPagerAdapter extends FragmentPagerAdapter {
private final List<Fragment> mFragmentList = new ArrayList<>();
private final List<String> 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 addFrag(Fragment fragment, String title) {
mFragmentList.add(fragment);
mFragmentTitleList.add(title);
}
@Override
public CharSequence getPageTitle(int position) {
return mFragmentTitleList.get(position);
}
}
}
