seems like btnDish is null. Are you assigning it a value somewhere in code above?

You should be doing something like


btnDish = findViewById(R.id.btnDish)
btnDish.setOnClickListner { 
   //do stuff here
}

yes but I set INTENT on OnClickListner – safeer ahmad Dec 17 '20 at 07:51
what should I do here? I just want to open the next activity by clicking button – safeer ahmad Dec 17 '20 at 07:52
no, i am not assigning it a value, I just declared it and set OnCLickListnere on btnDish just to open the next Activity – safeer ahmad Dec 17 '20 at 07:54
You need to assign `btnDish` the actual value before using it, thats line 1 of my code snippet. – georkost Dec 17 '20 at 08:01

  Button button = (Button) findViewById(R.id.button_send);
  button.setOnClickListener(new View.OnClickListener() {
  
  public void onClick(View v) {
      Intent intent = new Intent(FirstActivity.this,SecondActivity.class);
      startActivity(intent);
     }
  });

Please add some description of your suggestion. – Federico Navarrete Dec 17 '20 at 10:06
error occurred because you are using btn.findViewById(); replace "." with "=" i.e btn=findViewById(R.id.btnid); – developer Dec 17 '20 at 10:48
Hi developer, please edit the question and add your answer there. It's pretty common only to share the code, but it's important to provide a description if you want to get positive results. – Federico Navarrete Dec 21 '20 at 08:17
