Show help message onFocus of Edittext android

I want to show some help text(much like in a webpage when a field is focused a non-modal popup is shown about what to enter in the field).

I have used android:hint attribute of EditText but that clips the text if it is long. Is there any built in or quick way of doing this?

Add a TextView below your EditText that contains the hint. By default set it to be invisible.

<EditText
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
/>
<TextView
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:text="your hint message..."
/>

Now add a onFocusChangeListener to make the TextView visible / invisible:

editText.setOnFocusChangeListener(new OnFocusChangeListener() {
    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        if(hasFocus){
            tvHint.setVisibility(View.VISIBLE);
        }else{
            tvHint.setVisibility(View.INVISIBLE);
        }
    }
});

you can use Custom Toast massages or PopupWindow for non-modal popup like web see these likes help u creating custom Toast and popupwindow

https://github.com/quiqueqs/Toast-Expander/blob/master/src/com/thirtymatches/toasted/ToastedActivity.java

http://www.mobilemancer.com/2011/01/08/popup-window-in-android/

and use OnFocusChangeListener Listener for tracking when user clicked on EditView or when leavening focus

txtEdit.setOnFocusChangeListener(new OnFocusChangeListener() {          

        public void onFocusChange(View v, boolean hasFocus) {
            if(!hasFocus)
               //show Toast massages or PopupWindow     here           
        }
    });

Have a TextView just below the EditText. Implement the onFocusListener of the edittext and when the edit text has focus set the textView visibility to View.VISIBLE which will display the help text. And when the edit text loses its focus make the textview invisible.
