隐藏输入键盘

参考一些文章后，自己写的。  

    EditText  mEdtTitle = (EditText)viewfindViewById(R.id.titleEditText);
    mEdtTitle.setGravity(Gravity.VERTICAL_GRAVITY_MASK);
    mEdtTitle.setFocusable(true);
    mEdtTitle.requestFocus();

     private void _hiddenInputFromWindow(View v) {
        InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        if(imm.isActive()){
            imm.toggleSoftInput(InputMethodManager.SHOW_IMPLICIT, InputMethodManager.HIDE_NOT_ALWAYS);
        }
    }
