}
but if i directly load child Fragment(SettingsParent) from my activity it works perfect without action bar.
can someone help or with better approach but i don't want to use activity i need fragment with action bar.

i solved my problem by removing
app:layout_scrollFlags="scroll|enterAlways"
from:
<android.support.v7.widget.Toolbar
android:id="#+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="#style/ThemeOverlay.AppCompat.Light" />
now it is listening to my every damn touch :D
Happy coding

Blank activity is showing after destroying all fragments

I have created a main activity which has a fragment container in it, I am replacing many fragments in it on navigation menu option select. Its working fine, but the problem is:
When I click a navigation item twice, two identical fragments open, i have to press the back button twice to go back.
When all fragments are destroyed after pressing back, I see an empty page (which may be main activity page I guess).

Please suggest me on this.

This will fix your second problem, when you add fragments to your container they will be add to the stack,
if (getSupportFragmentManager().getBackStackEntryCount() == 1) {
finish();
}
else {
super.onBackPressed();
}
so when the stack entry count is 1 you have to finish the activity.
For the first problem you have to use "pop back stack" while adding the same fragment again use : getSupportFragmentManager().popBackStack();

BottomNavigationView keeps checking last menuitem (when it starts up) but displays first menuitem

When the app first starts up, it checks the last menuitem as if it was clicked. It displays the first menuitem content. In Android Studio, no errors, warnings, or logs are displayed that hint at anything going wrong.
Once the app is running, if I click on any of the other menuitems, it works normal. I can click on each of the menuitems and the correct fragment populates accordingly.
Here is MainActivity.java:
public class MainActivity extends AppCompatActivity {
private static final String SELECTED_ITEM = "arg_selected_item";
private BottomNavigationView mBottomNav;
private int mSelectedItem;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mBottomNav = (BottomNavigationView) findViewById(R.id.navigation);
mBottomNav.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
selectFragment(item);
return true;
}
});
MenuItem selectedItem;
if (savedInstanceState != null) {
mSelectedItem = savedInstanceState.getInt(SELECTED_ITEM, 0);
selectedItem = mBottomNav.getMenu().findItem(mSelectedItem);
} else {
selectedItem = mBottomNav.getMenu().getItem(0);
}
selectFragment(selectedItem);
}
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putInt(SELECTED_ITEM, mSelectedItem);
super.onSaveInstanceState(outState);
}
#Override
/* This is never called on start up */
public void onBackPressed() {
MenuItem homeItem = mBottomNav.getMenu().getItem(0);
if (mSelectedItem != homeItem.getItemId()) {
// select home item
selectFragment(homeItem);
} else {
super.onBackPressed();
}
}
private void selectFragment(MenuItem item) {
Fragment frag = null;
// init corresponding fragment
switch (item.getItemId()) {
case R.id.menu_home:
frag = HomeFragment.newInstance();
break;
case R.id.menu_archives:
frag = ArchivesFragment.newInstance();
break;
case R.id.menu_inspirational:
frag = InspirationalFragment.newInstance();
break;
case R.id.menu_search:
frag = SearchFragment.newInstance();
break;
}
// update selected item
mSelectedItem = item.getItemId();
// unchecked the other items.
//THIS LINE HERE
for (int i = 0; i < mBottomNav.getMenu().size(); i++) {
MenuItem menuItem = mBottomNav.getMenu().getItem(i);
menuItem.setChecked(menuItem.getItemId() == mSelectedItem);
}
updateToolbarText(item.getTitle());
if (frag != null) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(R.id.container, frag, frag.getTag());
ft.commit();
}
}
private void updateToolbarText(CharSequence text) {
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setTitle(text);
}
}

Here is a screenshot of when it first boots up:
Why is the last menuitem being checked and not the first menuitem?
EDIT:
So, from answers given below, I made this change and it works:
private void selectFragment(MenuItem item) {
Fragment frag = null;
// update selected item
mSelectedItem = item.getItemId();
// unchecked the other items.
for (int i = 0; i < mBottomNav.getMenu().size(); i++) {
MenuItem menuItem = mBottomNav.getMenu().getItem(i);
menuItem.setChecked(false);
}
// init corresponding fragment
switch (mSelectedItem) {
case R.id.menu_home:
frag = HomeFragment.newInstance();
mBottomNav.getMenu().findItem(R.id.menu_home).setChecked(true);
break;
case R.id.menu_archives:
frag = ArchivesFragment.newInstance();
mBottomNav.getMenu().findItem(R.id.menu_archives).setChecked(true);
break;
case R.id.menu_inspirational:
frag = InspirationalFragment.newInstance();
mBottomNav.getMenu().findItem(R.id.menu_inspirational).setChecked(true);
break;
case R.id.menu_search:
frag = SearchFragment.newInstance();
mBottomNav.getMenu().findItem(R.id.menu_search).setChecked(true);
break;
}
updateToolbarText(item.getTitle());
if (frag != null) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(R.id.container, frag, frag.getTag());
ft.commit();
}
}
Why would the THIS LINE HERE in the above code cause it to do this weird error?

Hope this may help you to resolve your issue.
Call this method whenever you change the Fragment. Pass checkedcolor and unchecked color according to your needs.
private void changeMenuItemCheckedStateColor(int checkedColor, int uncheckedColor) {
int[][] states = new int[][]{
new int[]{-android.R.attr.state_checked}, // unchecked
new int[]{android.R.attr.state_checked}, // checked
};
int[] colors = new int[]{
uncheckedColor,
checkedColor
};
ColorStateList colorStateList = new ColorStateList(states, colors);
bottomNavigationView.setItemTextColor(colorStateList);
bottomNavigationView.setItemIconTintList(colorStateList);
}

There is 2 Solutions
1) Use Group
<group android:checkableBehavior="single">
<item .../>
<item .../>
<item .../>
</group>
2) Do it by programmatically
Menu bottomMenu;
BottomNavigationView bottomNavigationMenu = (BottomNavigationView) findViewById(R.id.bottom_navigation);
bottomMenu = navigation.getMenu();
bottomMenu.findItem(R.id.menu_home).setChecked(true);
Hope it will help , If you have any queries please comment.

Remove below code:
// unchecked the other items.
for (int i = 0; i < mBottomNav.getMenu().size(); i++) {
MenuItem menuItem = mBottomNav.getMenu().getItem(i);
menuItem.setChecked(menuItem.getItemId() == mSelectedItem);
}
and give tint color in BottomNavigationView:
<android.support.design.widget.BottomNavigationView
android:id="#+id/navigation"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_gravity="start"
app:itemIconTint="#drawable/nav_item_color_state"
design:menu="#menu/bottom_nav_items" />

Android BottomNavigationView menuItem set checked doesn't work properly

In my bottomNavigationView I can change programmaticaly my menu items everything it seems to work, but in fact my layout is diferent from if is checked or if I click directly on tab. Please look at differences bellow:
1) for menuItem.setChecked(true):
2) when a user clicks directly on icon it will perform the animation and show it on the correct
Well what I real want is to select the menuItem as if the user clicked. Isn't supposed to work by doing menuItem.setChecked(true)?
Please take into consideration the following definition layout for menu items:
<item android:id="#+id/menu_home"
android:title="#string/menu_home"
android:icon="#drawable/ic_home_black_24dp"
app:showAsAction="ifRoom" />
<item android:id="#+id/menu_hall_of_fame"
android:title="#string/menu_hall_of_fame"
android:icon="#drawable/ic_stars_black_24dp"
app:showAsAction="ifRoom" />
<item android:id="#+id/menu_info"
android:title="#string/menu_info"
android:icon="#drawable/ic_info_black_24dp"
app:showAsAction="ifRoom" />
<item android:id="#+id/menu_settings"
android:title="#string/menu_settings"
android:icon="#drawable/ic_settings_black_24dp"
app:showAsAction="ifRoom" />
and how I'm checking the correct menuItem:
MenuItem item = mBottomNav.getMenu().findItem(R.id.menu_about);
// update selected item
mSelectedItem = item.getItemId();
// uncheck the other items and select the one.
for (int i = 0; i< mBottomNav.getMenu().size(); i++) {
MenuItem menuItem = mBottomNav.getMenu().getItem(i);
menuItem.setChecked(menuItem.getItemId() == mSelectedItem);
}
There is another method to perform a selection of a menuItem? What am I missing here?

See This i post here all code
public class MainActivity extends AppCompatActivity {
private static final String SELECTED_ITEM = "arg_selected_item";
private BottomNavigationView mBottomNav;
private int mSelectedItem;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mBottomNav = (BottomNavigationView) findViewById(R.id.navigation);
mBottomNav.setOnNavigationItemSelectedListener(new BottomNavigationView.OnNavigationItemSelectedListener() {
#Override
public boolean onNavigationItemSelected(#NonNull MenuItem item) {
selectFragment(item);
return true;
}
});
MenuItem selectedItem;
if (savedInstanceState != null) {
mSelectedItem = savedInstanceState.getInt(SELECTED_ITEM, 0);
selectedItem = mBottomNav.getMenu().findItem(mSelectedItem);
} else {
selectedItem = mBottomNav.getMenu().getItem(0);
}
selectFragment(selectedItem);
}
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putInt(SELECTED_ITEM, mSelectedItem);
super.onSaveInstanceState(outState);
}
#Override
public void onBackPressed() {
MenuItem homeItem = mBottomNav.getMenu().getItem(0);
if (mSelectedItem != homeItem.getItemId()) {
// select home item
selectFragment(homeItem);
} else {
super.onBackPressed();
}
}
private void selectFragment(MenuItem item) {
Fragment frag = null;
// init corresponding fragment
switch (item.getItemId()) {
case R.id.menu_home:
frag = MenuFragment.newInstance(getString(R.string.text_home),
getColorFromRes(R.color.color_home));
break;
case R.id.menu_notifications:
frag = MenuFragment.newInstance(getString(R.string.text_notifications),
getColorFromRes(R.color.color_notifications));
break;
case R.id.menu_search:
frag = MenuFragment.newInstance(getString(R.string.text_search),
getColorFromRes(R.color.color_search));
break;
}
// update selected item
mSelectedItem = item.getItemId();
// uncheck the other items.
Menu menu = mBottomNav.getMenu();
for (int i = 0, size = menu.size(); i < size; i++) {
MenuItem menuItem = menu.getItem(i);
((MenuItemImpl) menuItem).setExclusiveCheckable(false);
menuItem.setChecked(menuItem.getItemId() == R.id.menu_home);
((MenuItemImpl) menuItem).setExclusiveCheckable(true);
}
updateToolbarText(item.getTitle());
if (frag != null) {
FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
ft.add(R.id.container, frag, frag.getTag());
ft.commit();
}
}
private void updateToolbarText(CharSequence text) {
ActionBar actionBar = getSupportActionBar();
if (actionBar != null) {
actionBar.setTitle(text);
}
}
private int getColorFromRes(#ColorRes int resId) {
return ContextCompat.getColor(this, resId);
}
}
you can use this code
Menu menu = mBottomNav.getMenu();
for (int i = 0, size = menu.size(); i < size; i++) {
MenuItem menuItem = menu.getItem(i);
((MenuItemImpl) menuItem).setExclusiveCheckable(false);
menuItem.setChecked(menuItem.getItemId() == R.id.menu_home);
((MenuItemImpl) menuItem).setExclusiveCheckable(true);

I followed the android guideline and completed a layout looks like this:
<android.support.v4.widget.DrawerLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/drawer_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"

<LinearLayout
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical">

android:layout_height="wrap_content"
android:layout_width="match_parent"
/>
<FrameLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="#+id/fragmentContainer"/>
</LinearLayout>
<LinearLayout
android:id="#+id/left_drawer_view"

android:layout_height="match_parent"
android:orientation="vertical"
android:layout_gravity="start">
<RelativeLayout

<ImageView

android:textColor="#fff"
android:layout_alignParentBottom="true"
android:layout_alignParentLeft="true"

android:layout_margin="10dp"/>
</RelativeLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_weight="5"
android:orientation="vertical"

>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:drawablePadding="5dp"
android:id="#+id/side_item_activities"
android:padding="5dp"
android:gravity="center_vertical"
android:drawableLeft="#drawable/ic_menu_search_holo_light"/>
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Settings"
android:drawablePadding="5dp"
android:id="#+id/side_item_settings"
android:padding="5dp"
android:gravity="center_vertical"
android:drawableLeft="#drawable/ic_action_settings"
/>
</LinearLayout>
</LinearLayout>
</android.support.v4.widget.DrawerLayout>
FYI, I did not use Android.R.Id, but my own R.id.fragmentContainer to load the fragments. But apparently, the drawer layout is under the fragment loaded in the FrameLayout. If I click the item on the DrawerLayout, the fragments receive the gesture, not the DrawerLayout, although it still display correctly.
I need your two cents, guys. All answers and comments are appreciated.
Edit:
Here is the requested code.

}
}
}
}

The issue i found is in the onClick() method. Try changing the function as below
public Fragment findVisibleFragment() {
FragmentManager manager = getSupportFragmentManager();
Fragment fragment = manager.findFragmentById(R.id.fragmentContainer);
return fragment;
}
Edit:
set the same listener to multiple views.
sideBarHome.setOnClickListener(clickListener);
sideBarSettings.setOnClickListener(clickListener);
Refer this clicklistener object to the view and you can use the same logic to differentiate views
View.OnClickListener clickListener = new View.OnClickListener() {
#Override
public void onClick(View view) {
if (view.getId() == R.id.side_item_home) {
// mDrawerLayout.closeDrawers();
if (!(findVisibleFragment() instanceof SlidingTabFragment)) {
pushFragments("activities", homeFragment, true);
}
}
else if() {
//rest click logic
}
}
};
