如何使用按钮从 firebase 列表适配器和 firebase 中删除项目

Question

I have an activity that reads data from firebase database and displays the data in a firebase list adapter. Each item in the list view has 2 edit text and a button for deleting the item from both the list view and the firebase database. Below is the code for displaying the firebase list adapter

      adapter =new FirebaseListAdapter <TravelDetails>
   ( options){
  protected void populateView(View v, TravelDetails model, int position) {
Button delete=(Button)v.findViewById(R.id.button_accept);
final TextView z=(TextView)v.findViewById(R.id.dropoff);
final TextView text=(TextView)v.findViewById(R.id.txref);
text.setText(model.getTxt_Ref());
 z.setText(model.getDropoffspot());
 delete.setOnClickListener(new View.OnClickListener() {
     @Override
     public void onClick(View v) {.....

The list view works fine. Data is loaded from firebase, but I want to be able to use this button delete to delete items from both the list view and firebase database. I did research and only found ways on item click and not using a button, an example is this Android studio remove items from both listview and firebase but I don't know how to apply the principle to the button associated with the item from the database. Kindly render assistance

Below is the code of my adapter class public class TravelDetails {

    private String dropoffspot;
    private String txt_Ref;

    public TravelDetails(){

    }


    public String getDropoffspot(){
    return dropoffspot;
     }
    public void setDropoffspot(String dropoffspot){
    this.dropoffspot=dropoffspot;
    }

    public String getTxt_Ref() {
    return txt_Ref;
    }

       public void setTxt_Ref(String txt_Ref) {
       this.txt_Ref = txt_Ref;
     }

  } 

Answer 1

You can do this way inside your adapter

// make this function inside your adapter

protected void populateView(View v, ArrayList<TravelDetails> models, final int position) {
    Button delete=(Button)v.findViewById(R.id.button_accept);
    final TextView z=(TextView)v.findViewById(R.id.dropoff);
    final TextView text=(TextView)v.findViewById(R.id.txref);
    text.setText(model.getTxt_Ref());
    z.setText(model.getDropoffspot());
    delete.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            // code to delete from firebase
            models.remove(position); // delete from adapter array list
            notifyDataSetChanged(); // refresh adapter
        }
    }
}

I found out how to solve my problem. I simply add this in the delete buttons on click method.

         public void onClick(View v) {
         DatabaseReference item=adapter.getRef(position) ;
         item.removeValue();

} });
