【XFeng安卓开发笔记】edittext中怎样禁止系统自带键盘弹出但光标还在

网上又不少方法，均告失败，最终找到以下的方法：

// 隐藏系统键盘
    public void hideSoftInputMethod(EditText ed) {
        getWindow().setSoftInputMode(
                WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);

        int currentVersion = android.os.Build.VERSION.SDK_INT;
        String methodName = null;
        if (currentVersion >= 16) {
            // 4.2
            methodName = "setShowSoftInputOnFocus";
        } else if (currentVersion >= 14) {
            // 4.0
            methodName = "setSoftInputShownOnFocus";
        }

        if (methodName == null) {
            ed.setInputType(InputType.TYPE_NULL);
        } else {
            Class<EditText> cls = EditText.class;
            Method setShowSoftInputOnFocus;
            try {
                setShowSoftInputOnFocus = cls.getMethod(methodName,
                        boolean.class);
                setShowSoftInputOnFocus.setAccessible(true);
                setShowSoftInputOnFocus.invoke(ed, false);
            } catch (NoSuchMethodException e) {
                ed.setInputType(InputType.TYPE_NULL);
                e.printStackTrace();
            } catch (IllegalAccessException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (IllegalArgumentException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            } catch (InvocationTargetException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
        }
    }
