Hello, I'm getting an exception when Toast.makeText is executed:

public void onClick(View view){
(...)
CharSequence text1 = "Please insert a number.";
 int id= view.getId();
(...)
    else if(id== R.id.buttonOK){
                if(editText.getText().toString().matches(""))
                {
                    Toast.makeText(view.getContext(), text1, Toast.LENGTH_SHORT).show();
                }

I have already tried to use as the first argument:

getApplicationContext ()

this

MyActivity.this

view.getContext ()

But I always get the same exception. I've already changed the text1 and I still get the exception. I put a Log.d inside the IF to see if the problem was in the IF, but I can get inside the IF, the exception is generated in the Toast.makeText.

Exception:

Any ideas for solving this?

Your mistake was an indentation:

public void onClick(View view){
(...)
CharSequence text1 = "Please insert a number.";
 int id= view.getId();
(...)
    else if(id== R.id.buttonOK){
                if(editText.getText().toString().matches(""))
                {
                    Toast.makeText(view.getContext(), text1, Toast.LENGTH_SHORT).show();
                }

Correct:

public void onClick(View view){
(...)
CharSequence text1 = "Please insert a number.";
 int id= view.getId();
(...)

if(ALGUMA COISA){

...

} else if(id== R.id.buttonOK){
                if(editText.getText().toString().matches(""))
                {
                    Toast.makeText(view.getContext(), text1, Toast.LENGTH_SHORT).show();
                }
