How to make a TextView (or any other view) clickable on Android

Oftentimes developers want to use clickable labels (TextViews) in their applications to give it a Webish look and hopefully make the UI a little more familiar to smartphone users.

Luckily the Android SDK allows any view to be clickable; all we need to do is assign an OnClickListener callback handler to the targeted view.

Assume you have this TextView in your layout file

All you need then is to use the method setOnClickListener() of the view to assign a callback object to it. These callbacks are objects that implement the interface View.OnClickListener, as show below in the all-purposed method setupEventsListeners()

private void setupEventsListeners(){
  View myTextView = findViewById(R.id.myTextView);
  myTextView.setOnClickListener(new View.OnClickListener() {   
    @Override
    public void onClick(View caller) {
      Toast
      .makeText(caller.getContext(), 
                     "You have clicked on a TextView", 
                     Toast.LENGTH_LONG)
      .show();    
    }
  });     
}

You need to assign an click handler to it as soon as possible, let's say, when the activity is created.

@Override
protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  // your other initialization code here   
  setupEventsListeners();
}

And then you are done!
