android错误:The method makeText(Context, CharSequence, int) in the type
来源:互联网 发布:wifi网络延迟怎么设置 编辑:程序博客网 时间:2024/05/30 04:55
错误提示:
- The method makeText(Context, CharSequence, int) in the type Toast is not applicable for the arguments (new View.OnClickListener(){}, String, int)
错误原由:在makeText的第一个参数Context指的是上下文对象,而此处上下文并不是该Activity
,你必须使用 自己的Activity.this。如我的是Toast.makeText(MainActivity.this, "已经到了第一周", Toast.LENGTH_SHORT).show() 。
由于本人初写博客,写的不好的地方还请大家能批评指正,希望能和大家相互学习、相互交流、共同成长。
