Toast inside a Button OnclickListener is not worki

Question

This question already has an answer here:

• I am trying to display a toast when this button is pressed. But the code is not working 3 answers

intdelay was initialized at the beginning of the code by 1000. and I am trying to make sure that intdelay's value is updated by the value in the edit box by adding a toast when the button is clicked. but when I run the app, I get the following problem:

 Error:(46, 22) error: no suitable method found for makeText(<anonymous OnClickListener>,String,int)
method Toast.makeText(Context,CharSequence,int) is not applicable
(argument mismatch; <anonymous OnClickListener> cannot be converted to Context)
method Toast.makeText(Context,int,int) is not applicable
(argument mismatch; <anonymous OnClickListener> cannot be converted to Context)

This is the part of my code:

  @Override
        protected void onCreate(Bundle savedInstanceState) {
       super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        delayedttxt=(EditText)findViewById(R.id.delayedttxt);

    String delay=delayedttxt.getText().toString();       //this will get a string
    try{
        int intdelay = Integer.parseInt(delay);
   }catch(NumberFormatException ex){ // handle your exception
    }

    Button btn=(Button)findViewById(R.id.btn);
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            flashLight.switchFlash();
            Toast.makeText(this,"your integer is " + intdelay , Toast.LENGTH_LONG).show();
        }

    });

How can I solve that?

Answer 1

Try like this:

Toast.makeText(YourActivityName.this,"your integer is " + intdelay , Toast.LENGTH_LONG).show();

Answer 2

You are trying to show your toast inside the OnClickListener. The this keyword in this case refers to an instance of type OnClickListener, and not Context, like it is required.

You should use <YourActivityClass>.this to refer to the enclosing activity instance, that is a Context and can be use to show the toast.

Answer 3

You should change from

Toast.makeText(this,"your integer is " + intdelay , Toast.LENGTH_LONG).show();

to

Toast.makeText(getContext(),"your integer is " + intdelay , Toast.LENGTH_LONG).show();

Answer 4

That's because makeText wants to have a Context as a first argument. You are inside the onClick function of an OnClickListener. This means that this points to your OnClickListener.
You must have something like this

Toast.makeText(YourActivity.this,"your integer is " + intdelay , Toast.LENGTH_LONG).show();

Answer 5

Try inserting this line of code:

 Toast.makeText(getApplicationContext(),"your integer is " + intdelay , Toast.LENGTH_LONG).show();

Answer 6

Please do these in your activity,

Toast.makeText(getApplicationContext(),"your integer is " + intdelay , Toast.LENGTH_LONG).show();
