I'm having an issue in the Android app that I'm developing where a the text in a Fragment containing a TextView covers the bottom navigation if the text is too long. The issue looks like this:
TextView blocking bottom navigation
Here's the code for the Fragment:
package com.example.xxxxxx.loremipsum;

import android.view.ViewGroup;
import android.widget.Button;
import android.widget.TextView;
import android.widget.Toast;
/**

*/
public class LessonFragment extends Fragment
{
private String lessonContent;

public static LessonFragment newInstance(String param1, String param2)
{
return null;
}
#Override

{
super.onCreate(savedInstanceState);
if (getArguments() != null)
{
}
}
#Override

Bundle savedInstanceState)
{
View view = inflater.inflate(R.layout.fragment_lesson, container, false);
ConstraintLayout.LayoutParams layoutParams = new ConstraintLayout.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);

}
}
});
lesson = (TextView) view.findViewById(R.id.grammarContent);
String[] lessons;
if(!culture)
lessons = getActivity().getResources().getStringArray(R.array.lessons);
else
lessons = getActivity().getResources().getStringArray(R.array.cultureLessons);

return view;
}
#Override

public interface OnFragmentInteractionListener

}
}
Here's the XML for the Fragment:
<LinearLayout

xmlns:tools="http://schemas.android.com/tools"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="wrap_content"
tools:context="com.example.xxxxxx.loremipsum.LessonFragment">
<ScrollView
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:id="#+id/grammarContent"
android:textSize="18sp"

android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Back"
android:id="#+id/backButton"
tools:ignore="OnClick" />
</LinearLayout>
</ScrollView>
Finally, here's the XML for my MainActivity, where the Fragment is being added:
<?xml version="1.0" encoding="utf-8"?>

</android.support.constraint.ConstraintLayout>
EDIT: Here's a screenshot of a further issue:
Here's the bug I'm having
Please add one more layout in your MainActivity xml portion. And you also change in MainActivity R.id.fl_main with R.id.container

Your container should be an View which should be above BottomNavigationView. That's why you are having these conflicts. Because you just attach Fragment on parent view.
Set a background always to Fragment parent element. Because Fragment inflate on top of other to maintain stack.

i have been trying to fix this error but cant get it to work.
Here you find a picture of my problem the problem is that my text of the fragment is showing up in the navbar. i hope somebody can help me out with this!

Add an OnclickListener to the holder.text_number:
String message = "";
holder.text_number.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
message = textview.getText().toString();
Toast.makeText(getActivity(), "Message : " + message, Toast.LENGTH_LONG).show();
}
});
Now do whatever you want with the message String.
final TextView text_number2=(TextView)view.findViewById(R.id.text_calllog_number);
holder.text_number.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
Toast.makeText( context, "" + text_number2.getText().toString() , Toast.LENGTH_LONG).show();
}
});

If we quote Android | ListFragment
ListFragment has a default layout that consists of a single list view. However, if you desire, you can customize the fragment layout by returning your own view hierarchy from onCreateView(LayoutInflater, ViewGroup, Bundle).
And also from the documentation
your view hierarchy must contain a ListView object with the id "#android:id/list"
Let's call this **some_list_view.xml**
Notice not #+id/list, but #android:id/list
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingLeft="8dp"
android:paddingRight="8dp">
<!-- TODO: Add your buttons here -->
<ListView android:id="#id/android:list"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_weight="1"/>
<TextView android:id="#id/android:empty"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:text="No data"/>
</LinearLayout>
One of your error exists in onViewCreated. You have no inflater there.
Implement the other method like the documentation says.
And you don't need to find the ListView.
Use findViewById to find other views.
For example,
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.some_list_view, parent, false);
}
#Override
public void onViewCreated(View view, Bundle b) {
super.onViewCreated(view, b);
// Button filter1 = (Button) view.findViewById(...);
// filter1.setOnClickListener....
EventAdapter adaptor = new EventAdapter(getActivity(), mOrganization);
setListAdapter(adaptor);
// This is like calling fetchList()
ParseQuery.getQuery("Event").findInBackground(this);
}
#Override
public void done(List<ParseObject> scoreList, ParseException e) {
if (e == null) {
...
}
}
getListView() already will return you your ListView, therefore, notice I didn't need to find it. But if you did, this is how.
(ListView) view.findViewById(android.R.id.list);
So, that's just a matter of making an XML file with that mentioned ID value set to a ListView like shown above.
The setup I have is a main_activity fragment that just has welcome text, and when you tap the start button, it's supposed to switch fragments. Instead of replacing the current fragment, it just overlays it on top of the main_activity fragment and won't allow me to perform the action associated with the new fragment.

Don't replace your top-level view group. Create an empty frame layout inside of the top-level frame layout and use that as the ID to replace.
If you have elements in the main layout you no longer want visible you'll have to hide them (or use a fragment to show them in the first place which will get replaced).
UPDATE:
Still having the same problem, but I've added a fragment into the main_activity

ORIGINAL:
The setup I have is a main_activity fragment that just has welcome text, and when you tap the start button, it's supposed to switch fragments. Instead of replacing the current fragment, it just overlays it on top of the main_activity fragment and won't allow me to perform the action associated with the new fragment.
Main Activity example
quote_fragment overlapping main activity
