There are two ways of inserting a fragment of an activity and you are using both at the same time.
The first way is:
Declare the fragment inside the activity's layout file.
But in this case the fragment will be fixed on the activity like a view.
The second form is:
Programmatically add the fragment to an existing ViewGroup.
In this case you can add the fragment at any time to the activity, replace it with another fragment, remove the fragment when you want.
You can see what I'm telling you watching this link to the Android developer and looking "Adding a fragment to an activity".
Fragments Android Developers
Note: If you decide to programmatically add the fragment do not have to reference it in the XML Activity. On the other hand these lines would thus:
FragmentSongs songs=new FragmentSongs();
FragmentManager fm=getSupportFragmentManager();
FragmentTransaction transaction=fm.beginTransaction();
transaction.add(R.id.content,songs);
transaction.commit();
R.id.content: It is the id of the container in which you add the fragment programmatically in your case on the activitymain.xml LinearLayout. As you can see you did not like this but you linked the id of the fragment which is a mistake.
Well do not forget that you should not use two ways of adding the fragments so pick one and hope that what prompted you find it useful.

I have added an AutoCompleteTextView to my android project but when I click on the AutoCompleteTextView, the keyboard appears and disappears in a second.
But if I click the AutoCompleteTextView and quickly click on some characters, the keyboard doesn't disappear.
I do not understand why. How can I fix it?
if you need another piece of code ask me.

I have followed up your code and make it a demo but nothing happens just like you mentioned. If your view is static, then moving any code to the onActivityCreated method is not necessary. But when you - for instance, fill some lists from the adapter, then you should do it in the onActivityCreated method. Please check it out below:
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
AutoCompleteTextView editText = findViewById(R.id.autocomplete);
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
R.layout.custom_list_item, R.id.text_view_list_item, countriesList);
editText.setAdapter(adapter);
}
}

I have a popup menu inside every item on a listview. When you click the imageview to the left (settings img with 3 dots) a popup menu should showup. however, I'm getting error
Could not find a method showPopupMenu(View) in the activity class android.app.Application for onClick handler on view class android.widget.ImageView with id 'settings_img'
does anyone know what this error is. it is obvious that can't find the method, but is it because it can't find the class/view? if so how can I fix it? thanks

You should define your settings_img on your adapter getView and add a click listener for each element.
example:
ImageView settingsImgView = (ImageView) convertView.findViewById(R.id.settings_img);
settingsImgView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
context.showPopupMenu() //or popupmenu logic in here if you want
}
});
Usually, when it comes to the adapter, I pass the activity itself instead of the context. Then I pass the activity's context to super() and keep the activity in the field variable. That way I'm able to use all public methods of the parent activity.

I am trying to render TextEntryFragment(fragment) from this TextEntryActivity(activity).
I have kept a series of toasts in various places to track and I can see my code is getting executed till FragmentManager's FragmentTransaction and after that it does not seem to call the Fragment's onCreate/onCreateView.
Can anyone point me whats wrong ?
When I execute I am not able to see the fragment UI being rendered.
remove
if(m_f_text_entry_activity == null)
{
m_f_text_entry_activity = new Fragment();
m_fm_text_entry_activity.beginTransaction()
.add(R.id.fragmentContainer_TextEntry, m_f_text_entry_activity)
.commit();
}
and replace with
m_fm_text_entry_activity.beginTransaction()
.add(R.id.fragmentContainer_TextEntry, m_f_text_entry_activity)
.commit();
==================EDIT==================================
Also
TextEntryFragment m_f_text_entry_activity=new TextEntryFragment();
instead of
Fragment m_f_text_entry_activity = m_fm_text_entry_activity.findFragmentById(R.id.fragmentContainer_TextEntry);
I am very new to Android. I am trying to add a simple toggle button to a class which extends Fragment class.
I tried everything but I could not get it working. I managed to add a normal button but that is not useful for me.
All I want is add a toggle button.
Please help me.
Thanks all

((Button) view.findViewById(R.id.fragment_button))
.setOnClickListener(new OnClickListener() {
#Override

if (activity != null) {
Toast.makeText(activity,
R.string.toast_you_just_clicked_a_fragment,

}
});
return view;
}
}
Use This as an Example :
<LinearLayout
android:id="#+id/txtDayTypes"
android:layout_below="#+id/main_header"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal" >
<ToggleButton
android:id="#+id/tglDay1"
android:layout_width="160dp"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:text="Saturday"
android:textOn="Saturday"
android:textOff="Saturday"
android:checked="true"/>
</LinearLayout>
and you can Access it by :
if(currentButton != R.id.tglDay1) ((ToggleButton)findViewById(R.id.tglDay1)).setChecked(false);
