I faced infinite run when I am trying using ListView with retrieving data from firebase, and I don't know how can I solve it.
My main goal is retrieving from firebase with a dynamic number of clients who have a status of "Not approved".
This my RUN

public class approvedAdmin extends AppCompatActivity implements View.OnClickListener{

ListView listview;

public approvedAdmin() {
}
@Override
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_approved_admin);
listview=(ListView)findViewById(R.id.list);
dref= FirebaseDatabase.getInstance().getReference("client");
// adapter.notifyDataSetChanged();
dref.addChildEventListener(new ChildEventListener() {
@Override

String status;
String name;
String email;
Toast.makeText(approvedAdmin.this, "ok", Toast.LENGTH_SHORT).show();
for(DataSnapshot ds: dataSnapshot.getChildren() ){
if (ds.hasChild("Status")){
status=ds.child("Status").getValue(String.class);
if (status.equalsIgnoreCase("Not approved")){
name= ds.child("name").getValue(String.class);
list.add(name);
adapter= new ArrayAdapter<String>(approvedAdmin.this, android.R.layout.simple_list_item_1, list);
listview.setAdapter(adapter);
}}
}}
@Override

}
@Override

});
}
@Override

}
