关于android自定义键盘 隐藏系统键盘后 EditText无法正常获取光标的小记

转自：http://bbs.csdn.net/topics/390498445

当为隐藏系统键盘为 EditText 设置 setInputType(InputType.TYPE_NULL)后EditText无法正常获取光标

可对EditText进行如下设置：

    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 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();
            }  
        }  
    }
