how to block virtual keyboard while clicking on edittext in android?

Here is a website that will give you what you need.

As a summary, it provides links to InputMethodManager and View from Android Developers. It will reference to the getWindowToken inside of View and hideSoftInputFromWindow() for InputMethodManager

A better answer is given in the link, hope this helps.

EDIT

From the link posted above, here is an example to consume the onTouch event:

editText_input_field.setOnTouchListener(otl);

private OnTouchListener otl = new OnTouchListener() {
    public boolean onTouch (View v, MotionEvent event) {
            return true; // the listener has consumed the event
    }
 };

Here is another example from the same website. This claims to work but seems like a bad idea since your EditBox is NULL it will be no longer an editor:

MyEditor.setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View v, MotionEvent event) {
    int inType = MyEditor.getInputType(); // backup the input type
    MyEditor.setInputType(InputType.TYPE_NULL); // disable soft input
    MyEditor.onTouchEvent(event); // call native handler
    MyEditor.setInputType(inType); // restore input type
    return true; // consume touch event
}
});

Hope this points you in the right direction

A simpler way, is to set focusable property of edit text false. In your EditText's XML set android:focusable="false"

Another simpler way is adding android:focusableInTouchMode="false" line to your EditText's xml. Hope this helps.
