java - explain the syntax EditText editText = (EditText) findViewById(R.id.edit_message); -

  / ** is when a user clicks on Send Button / Send Public Empty Message (View View) {Intent to intent = new intent (this, DisplayMessageActivity.class); Edittext EditingTextX (Find Text) VVBIID (RaidAdit_message); String message = editText.getText (). ToString (); Intent.putExtra (EXTRA_MESSAGE, message); StartActivity; }
