I have a button in my Android Studio project.I want to implement a functionality that once a user clicks the button value is updated by once now if user clicks it again I dont want to update value. Edited These buttons are in recycler view

Just use a boolean. If the button is clicked set the boolean to true and check on each click if the boolean is false.

Should look something like this:

boolean wasClicked = false;

final Button button = findViewById(R.id.button_id);
         button.setOnClickListener(new View.OnClickListener() {
             public void onClick(View v) {
                 if(!wasClicked){
                     //Your actions for your button-click
                     wasClicked = true;
                 }
             }
         });

Button button = (Button)findviewbyId("Button ID")
boolen isClicked  = false;
public void onClick(View v){
 switch(v.getId()){
 case R.id."buttonID"{
  if(!isClicked)
 isClicked = true;
 updateData()// Your Method where your are updating the data;
 break;

}

public void updateData(){
   if(isClicked){
    "Update your data"
    }
  else{
    "do another action"
   }

This code is useful if you use RecyclerView.

public MyViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
    View view = LayoutInflater.from(mContext).inflate(R.layout.myview, parent, false);
    view.setOnClickListener(new View.OnClickListener() {
        public void onClick(View v) {
            // add some code
            view.setEnabled(false);
        }
    });
    return new MyViewHolder(view);
}

I think this code is useful if you use Button.

Button button = findViewById(R.id.button);
button.setOnClickListener(new View.OnClickListener() {
    public void onClick(View v) {
       // add some code
       button.setEnabled(false);
    }
});
