How to maintain multiple fragments on the resume of parent activity

How to maintain multiple fragments on the resume of parent activity - android

I am using navigation drawer which calls multiple fragments on the click of a list item of navigation drawer.
In my scenario, parent activity handles 2 fragments. There is an expected behavior that I am facing in handling these fragments.
Here is what I am doing:
Go to offline mode -> Go to fragment 2 -> Minimize the app -> Go to online mode ( switch on the internet ) - > Resume the app
On resume of the app, the parent activity is called and in parent activity, by default fragment 1 is opened, rather it should open fragment 2.
Help is appreciated.
Here is my navigation drawer code -
public class NavigationDrawer extends ActionBarActivity implements OnItemClickListener {
private ActionBar actionBar;
private DrawerLayout mDrawerLayout;
private ListView mDrawerList;
RelativeLayout user_panel;
LinearLayout mylinearlayout;
private ActionBarDrawerToggle mDrawerToggle;

#Override

setContentView(R.layout.activity_main_drawer);
// Initialize SharedPreferences mode
pref = getApplicationContext().getSharedPreferences("MyPref", 0);
editor = pref.edit();
username = pref.getString("name", null); // getting String
moveDrawerToTop();
initActionBar();
initDrawer();
//Quick cheat: Add Fragment 1 to default view

I follow many Tutorial but I didn't get solution Hope I'll get answer here. I have added recyclerview when I click on it it open fragment but when I click on back button instead of going back it goes to first Page.
How to go back to Fragment from Fragment when I click on Back button?

You can use Stack for holding the fragment instances. When you move to the next fragment push the fragment into the stack and detach it from your activity and in the onbackpressed event pop the fragment and attach it to the activity.

This is one of the best explanation that i came across when i started in SO for fragment navigation i hope it helps clear your understanding of how they work.
Android fragments navigation and backstack

Update an TextView in NavigationDrawer after input from user in previous activity

There is some information that I want to display in the NavigationDrawer. This information is entered by the user in a previous activity. I use an intent to send the information to the Main Activity for the Drawer.
MainActivity (After user entered details)
public class MainActivity extends AppCompatActivity implements FragmentDrawer.FragmentDrawerListener {
private static String TAG = MainActivity.class.getSimpleName();
private Toolbar mToolbar;
private FragmentDrawer drawerFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Intent intent = getIntent();
String info = intent.getStringExtra("info");
mToolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(mToolbar);
getSupportActionBar().setDisplayShowHomeEnabled(true);
drawerFragment = (FragmentDrawer)
getSupportFragmentManager().findFragmentById(R.id.fragment_navigation_drawer);
drawerFragment.setUp(R.id.fragment_navigation_drawer, (DrawerLayout) findViewById(R.id.drawer_layout), mToolbar);
drawerFragment.setDrawerListener(this);
// display the first navigation drawer view on app launch
displayView(0);
}
#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;
}
if(id == R.id.action_search){
Toast.makeText(getApplicationContext(), "Search action is selected!", Toast.LENGTH_SHORT).show();
return true;
}
return super.onOptionsItemSelected(item);
}
#Override
public void onDrawerItemSelected(View view, int position) {
displayView(position);
}
private void displayView(int position) {
Fragment fragment = null;
String title = getString(R.string.app_name);
switch (position) {
case 0:
fragment = new HomeFragment();
title = getString(R.string.nav_item_dashboard);
break;
......
}
I have a specific layout for the navigation drawer and it contains a textview which I want to update with the String test. This is the fragment code and the xml for it.

this.drawerListener = listener;
}

// preparing navigation drawer items
for (int i = 0; i < titles.length; i++) {
NavDrawerItem navItem = new NavDrawerItem();
navItem.setTitle(titles[i]);
navItem.setIcon(icons.getResourceId(i,-1));
data.add(navItem);
}
return data;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// drawer labels
titles = getActivity().getResources().getStringArray(R.array.nav_drawer_labels);
icons = getResources().obtainTypedArray(R.array.nav_drawer_icons);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflating view layout
View layout = inflater.inflate(R.layout.fragment_navigation_drawer, container, false);
recyclerView = (RecyclerView) layout.findViewById(R.id.drawerList);
TextView userID = (TextView) layout.findViewById(R.id.nav_title_user);
adapter = new NavigationDrawerAdapter(getActivity(), getData());
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
recyclerView.addOnItemTouchListener(new RecyclerTouchListener(getActivity(), recyclerView, new ClickListener() {

I have managed to update the list in the drawer with Icons, Labels and a Header. I have done so by using a RecyclerViewAdapter.
The problem that I am having is that these details were from the resources (strings.xml).
How can I update a textview on a NavigationFragment when it has been created? How can I send a value to the fragment so that it will be used during OnCreateView of the fragment?

I was looking too much into it. The solution was quite simple...Even though it took me 3 hrs to figure this out :/
In the NavigationFragment, I created a method to update a textview with a string. In the MainActivity where I get the information from the intent, I just called the method like this:
drawerFragment.setUserTextView(info);
This is why taking breaks are important... ^^

Android Navigation Drawer can't click on one item

I have a really interesting problem with my Navigator menu.
I have no idea why... But I can click on any item from my menu, I don't want to say I click and nothing happened. I really want to say I can't click on any item, all my menu it's like a big image.
I've try to make a new project witch already have Navigation Drawer Activity, of course it works.. but when I've try to copy that code and put on mine.. I have the same problem and vice versa, I've try to put my code into a new project with Navigation Drawer Activity, but again... I can't click on any item.
Here it's one image with my aplication.

How to hide soft input Keyboard when the Navigation drawer is being toggled , using fragments

So i have A navigation Drawer in the MainActivity and when a child of the expandable List View is being clicked the content is presented in a fragment.
Inside the fragment i have a Menu icon , when clicked a search textbox is being displayed and the soft input Keyboard. but if someone push the toggle button to open the navigation drawer the soft input keyboard doesn't disappear. I have tried this methods :
First method: closing keyboard from MainActivity from onDrawerClosed ,using this code, nothing happened :
getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
Second method : closing the Keyboard from MainActivity from the method onOptionsItemSelected(MenuItem item) , getting the item id and writing the same code as previous in the case : android.R.id.home, nothing happened
Third method : As the previous method but within the Fragment writing the above code, nothing happened :
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Service.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(ed_search.getWindowToken(), 0);
The soft Input Keyboard opens from the Fragment so i can't use something like the code in the above line because the ed_search is declared in the Fragment.
This is the code from the Main Activity:
public class MainActivity extends AppCompatActivity {
private static DrawerLayout mDrawerLayout;
private static ExpandableListView mExpandableListView;

Thanks in advance!

use this
public static void showKeyboard(Activity pActivity, View pView) {
if (pView == null) {
pView = pActivity.getWindow().getCurrentFocus();
} else {
/**
* For {#link EditText}, a call to {#link View#requestFocus()} will
* open the keyboard as per inputType set for {#link EditText}
*/
pView.requestFocus();
}
if (pView != null) {
InputMethodManager imm = (InputMethodManager) pActivity
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.showSoftInput(pView, InputMethodManager.SHOW_FORCED);
}
}
}
public static void hideKeyboard(View pView, Activity pActivity) {
if (pView == null) {
pView = pActivity.getWindow().getCurrentFocus();
}
if (pView != null) {
InputMethodManager imm = (InputMethodManager) pActivity
.getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
imm.hideSoftInputFromWindow(pView.getWindowToken(), 0);
}
}
}

I had a similar situation wherein I had search in the child fragment of the navigation drawer.
Now on searching the keyboard would pop up and when I wanted to click on the navigation drawer again the keyboard wouldn't hide so I mixed up the 2 solution above and came up with this.
mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, R.string.app_name, R.string.app_name) {
#Override
public void onDrawerSlide(View drawerView, float slideOffset){
hideKeyboard(true, ActivityName);
}
};
public static void hideKeyboard(boolean val, Activity activity) {
View view;
view = activity.getWindow().getCurrentFocus();
if (val == true) {
InputMethodManager inputMethodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
inputMethodManager.hideSoftInputFromWindow(view.getWindowToken(), 0);
}
}
and guess what this worked! thanks for your help!

ActionBar is not showing Title in Android

I want to implement Left & Right Side Slider Menu so I have set Right Side Slider in NavigationDrawerSlider which already have Left Side Slider by Default.
I am using ActionBarSherLock for this to support Application from Api 8. Slider is working fine but issue is that ActionBar is not showing Title.
Please help me to solve this issue. One more thing, When I Click on ImageView, It also fires ActionBarDrawerToggle. So, how to prevent this also ?
My Code:
public class MainActivity extends SherlockFragmentActivity {
private DrawerLayout mDrawerLayout;
private ListView mDrawerList_Left;
private ListView mDrawerList_Right;
private ActionBarDrawerToggle mDrawerToggle;
private ActionBar actionBar_Right;
private ArrayList<NavDrawerItem> navDrawerItems_Left;

mDrawerToggle.syncState();
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
mDrawerToggle.onConfigurationChanged(newConfig);
}
}
I have figured out that It is not showing title because of
actionBar_Right = getSupportActionBar();
actionBar_Right.setCustomView(R.layout.right_menu);
actionBar_Right.setDisplayShowTitleEnabled(true);
actionBar_Right.setDisplayShowCustomEnabled(true);
What to do for this ?

For showing the title in the ActionBar setTitle must be overridden:
#Override
public void setTitle(CharSequence title)
{
this.title = title;
getSupportActionBar().setTitle(title);
}
