fragments and bottomNavigationView

fragments and bottomNavigationView - java

enter image description hereI'm totally new in android studio and java.
I created one bottomNavigation for my app and I used 3 fragments and it's totally fine and working.
but now I want to add one seekBar and click listener on one of my fragments but I couldn't do it.
my question is in which life cycle view or function I have to add this seek bar click listener?
I want to add this code as a seekbar listener
seekBar.findViewById(R.id.seekBar);
textView.findViewById(R.id.textView3);
seekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
#Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
textView.setText(progress+"/100");
}
#Override
public void onStartTrackingTouch(SeekBar seekBar) {
}
#Override
public void onStopTrackingTouch(SeekBar seekBar) {
}
});

For this, you actually need separate java files that, in the class declaration, extends 'Fragment'. This is a really good youtube video for it:

Hope this helps.

I cannot add any function for my fragment's java files

UPDATES
I added more java files just in case you find them helpful. I figured that I may need to write codes to connect between MainActivity.java and my fragments, but the codes I followed from several YouTube videos do not work. I would be greatly appreciated if you can write me a line of code to connect the fragment.
END OF UPDATES
Whenever I try to add functions in my fragment file, it does not work. I think I may miss some codes in MainActivity.java, but I have no idea what to add to make my fragment's java files work.
Here is my fragment's java file (I did not touch anything but added a simple function to show a check mark when a button is clicked):
package com.example.dailybible3;

import android.widget.Button;
import android.widget.ImageView;
import android.widget.Toast;
/**

* Use the {#link FragmentBible#newInstance} factory method to
* create an instance of this fragment.
*/
public class FragmentBible extends Fragment {
// TODO: Rename parameter arguments, choose names that match
// the fragment initialization parameters, e.g. ARG_ITEM_NUMBER
private static final String ARG_PARAM1 = "param1";
private static final String ARG_PARAM2 = "param2";
// TODO: Rename and change types of parameters
private String mParam1;
private String mParam2;
public FragmentBible() {
// Required empty public constructor
}
/**
* Use this factory method to create a new instance of
* this fragment using the provided parameters.
*
* #param param1 Parameter 1.

* #return A new instance of fragment fragment_bible.
*/
// TODO: Rename and change types and number of parameters
public static FragmentBible newInstance(String param1, String param2) {
FragmentBible fragment = new FragmentBible();
Bundle args = new Bundle();
args.putString(ARG_PARAM1, param1);
args.putString(ARG_PARAM2, param2);
fragment.setArguments(args);
return fragment;
}
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
if (getArguments() != null) {
mParam1 = getArguments().getString(ARG_PARAM1);
mParam2 = getArguments().getString(ARG_PARAM2);
}
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view = inflater.inflate(R.layout.fragment_bible, container, false);
Button btn_complete = (Button) view.findViewById(R.id.complete_button);
btn_complete.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
ImageView check_mark = (ImageView) view.findViewById(R.id.check_mark);
int visibility = check_mark.getVisibility();
if(visibility == View.VISIBLE)
{
check_mark.setVisibility(View.INVISIBLE);

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.

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();
}
});
Ten days I look for the answer .....Wadaane .... Thank you very much

Fragment overlapping another fragment instead of replacing it

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

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).

Fragment being displayed, overlaps current fragment instead of replacing it

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

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

fragments and bottomNavigationView - java

For this, you actually need separate java files that, in the class declaration, extends 'Fragment'. This is a really good youtube video for it: https://www.youtube.com/watch?v=bNpWGI_hGGg Hope this helps.
