Question

In my application , I am dynamically generating a linearlayout that contains an edittext and some Buttons .

I want that when the user presser the ‘enter’ on the keyboard of device the keyboard should hide

I tried it by setting the input type of the edittext , But by this when the user presses “enter” it moves onto another edittext .

How can i do that??

Answer 1

Try the following:

final EditText et = new EditText(this);
        et.setId(id[i][0]);
        et.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
        et.setTypeface(Typeface.SERIF);

et.setOnKeyListener(new View.OnKeyListener()
        {

            @Override
            public boolean onKey(View editView, int keyCode, KeyEvent event)
            {
                Context mContext = Page1.this;
                if( keyCode == KeyEvent.KEYCODE_ENTER ){
                    et.clearFocus();
                    InputMethodManager imm = (InputMethodManager) mContext.getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(et.getWindowToken(),0);
                    return true;
                }
                return false;
            }
        })
