只显示上面menu

        }
        } catch (Exception ex) {
        }

默认弹出软键盘

 mInfoEdit.setFocusable(true);
                 mInfoEdit.setFocusableInTouchMode(true);
                 mInfoEdit.requestFocus();
                Timer timer = new Timer();
                 timer.schedule(new TimerTask()
                {
                   public void run()
                 {
                   InputMethodManager inputManager =
                  (InputMethodManager)mInfoEdit.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
                  inputManager.showSoftInput(mInfoEdit, 0);
                  }
                 },500);
