我正在一个应用程序中工作，我从Fragment1调用Fragment2，当我在Fragment2中按默认返回按钮时，它会带我回到Fragment1，但是当我按其他按钮并调用getActivity.finish()时，它会关闭我的Activity。
我已经添加了下面的代码:
MainActivity.java
public class MainActivity extends AppCompatActivity {
AHBottomNavigation bottomNavigation;
Fragment selectedFragment = null;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bottomNavigation = (AHBottomNavigation) findViewById(R.id.navigation);
AHBottomNavigationItem item1 = new AHBottomNavigationItem(R.string.home, R.drawable.home, R.color.colorAccent);
AHBottomNavigationItem item2 = new AHBottomNavigationItem(R.string.menu, R.drawable.menu, R.color.colorAccent);
AHBottomNavigationItem item3 = new AHBottomNavigationItem(R.string.cart, R.drawable.cart, R.color.colorAccent);
AHBottomNavigationItem item4 = new AHBottomNavigationItem(R.string.orders, R.drawable.orders, R.color.colorAccent);
AHBottomNavigationItem item5 = new AHBottomNavigationItem(R.string.settings, R.drawable.setting, R.color.colorAccent);
bottomNavigation.addItem(item1);
bottomNavigation.addItem(item2);
bottomNavigation.addItem(item3);
bottomNavigation.addItem(item4);
bottomNavigation.addItem(item5);
bottomNavigation.setTitleState(AHBottomNavigation.TitleState.ALWAYS_SHOW);
bottomNavigation.setAccentColor(Color.parseColor("#571e19"));
selectedFragment = ItemHomeFragment.newInstance(bottomNavigation);
bottomNavigation.setOnTabSelectedListener(new AHBottomNavigation.OnTabSelectedListener() {
@Override
public boolean onTabSelected(int position, boolean wasSelected) {
if (position == 0) {
selectedFragment = ItemHomeFragment.newInstance(bottomNavigation);
} else if (position == 4) {
selectedFragment = Fragment1 (bottomNavigation);
}
android.app.FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frame_layout,selectedFragment);
fragmentTransaction.commit();
return true;
}
});
android.app.FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(R.id.frame_layout, ItemHomeFragment.newInstance(bottomNavigation));
fragmentTransaction.commit();
}
public void setNotification(){
bottomNavigation.setNotification("1", 1);
}
}
Fragment1.java
public class Fragment1 extends Fragment {
public static AHBottomNavigation bottomNavigation1;
TextView txtLogout,txtMyProfile,txtTermsCondition,txtRate;
public int LANGUAGE_REQUEST_CODE = 113;
private SharedPreferences prefs ;
Boolean languageBoolean = true;
MyApplication myApplication;
private UIView uiView = UIView.getInstance();
ProgressDialog pDialog;
static int index;
public static ItemSettingsFragment newInstance(AHBottomNavigation bottomNavigation) {
ItemSettingsFragment fragment = new ItemSettingsFragment();
bottomNavigation1 = bottomNavigation;
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
showNotificationCounter(32);
View view = inflater.inflate(R.layout.fragment_settings, container, false);
TextView txtLanguage = (TextView) view.findViewById(R.id.txtLanguage);
txtLanguage.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Intent intent = new Intent(getActivity(), LanguageActivity.class);
startActivity(intent);
}
});
txtMyProfile.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
ProfileFragment fragment2 = new ProfileFragment();
android.app.FragmentManager fragmentManager = getFragmentManager();
android.app.FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
fragmentTransaction.replace(android.R.id.content, fragment2);
fragmentTransaction.addToBackStack(null);
fragmentTransaction.commit();
}
});
return view;
}
Fragment2.java
public class Fragment2 extends Fragment{
public Fragment2() { }
public static Fragment newInstance() {
Fragment2 profileFragment = new Fragment2();
return profileFragment;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.language, container, false);
TextView fragment2 = (TextView) view.findViewById(R.id.txtLanguage);
fragment2.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
getActivity().finish();
}
});
return view;
}
}
