Do you mean TextView or EditText?

In case of EditText you can use a TextWatcher. Here you can use the method "onTextChanged".

TextView dont receive key pressed. You need an EditText to do this.

Follow the code below:

editText.addTextChangedListener(new TextWatcher() {          
@Override
public void onTextChanged(CharSequence s, int start, int before, int count) {                                   
   //here is your code
}                       
@Override
public void beforeTextChanged(CharSequence s, int start, int count,int after) {
   // TODO Auto-generated method stub                          
}                       
@Override
public void afterTextChanged(Editable s) {
   // TODO Auto-generated method stub                          
}
});
