Issue
I have a Navigation drawer that has four different fragments. On the Home Fragment Dashboard, I have eight different image buttons that I want to open a new activity I.E. when you click the Image Button TM's I want it to open the TM's activity. I'm using kotlin as well.
I've watched numerous videos and forums on YouTube and google and none have seemed to work for what I'm doing.
// Dashboard.kt is where I have my ImageButtons, where I want each button to open a new activity.
package com.example.militarymainenance
import android.os.Bundle
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.fragment.app.Fragment
class Dashboard : Fragment() {
override fun onCreateView(
inflater: LayoutInflater, container: ViewGroup?,
savedInstanceState: Bundle?
): View? {
// Inflate the layout for this fragment
return inflater.inflate(R.layout.fragment_dashboard, container, false)
}
}
// fragment_dashboard.xml is where I have my ImageButtons, where I want each button to open a new activity.

Solution
You should create ImageButton view in your xml file, then bind onClickListener to it and call startActivity when onClick triggers.
just an example to understand:
public class TabFragment1 extends Fragment {
ImageButton imageButton;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.fragment_tab_fragment1, container, false);
imageButton = (ImageButton)view.findViewById(R.id.imageButton);
imageButton.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
startActivity(getActivity(),NewActivity.class);
}
});
return view;}
