Android – the prompt does not disappear on EditText

I have an EditText:

<EditText 
    android:hint="Your Notes" android:id="@+id/tv_notes_data"
    android:layout_width="wrap_content" android:layout_height="wrap_content"
    android:gravity="right" style="@style/items_description_plain" />

When the user clicks it, I need the prompt to disappear, but this will never happen. Please tell us why

resolvent:

Try using onclicklistener:

editText.setOnClickListener(new OnClickListener {
    void onClick(View v) {
        editText.setHint("");
        // or ((EditText) v).setHint(""));
    }
});

To set the prompt again, you can use:

editText.setOnFocuschangelistener(new OnFocuschangelistener {
    void OnFocusChange(params) {
        editText.setHint("Your Notes");
    }
});

By the way, the prompt will disappear only when the user starts typing. In fact, although there are no characters in EditText, the prompt will be displayed
