Answer 1

Salesmandistributorlistitem是一个适配器，因此无需在manifest文件中注册它。

所以从清单

中删除以下行

 <activity android:name=".salesmanjob.Salesmandistributorlistitem" android:screenOrientation="portrait"></activity>
//^^^^^^^ is activity but Salesmandistributorlistitem is extending adapter

Read, elements that can appear in the manifest file

Answer 2

错误＆＃34;没有默认构造函数＆＃34;意味着你需要添加一个像这样的无参数构造函数：

Salesmandistributordetails() {
}

然而，这并不意味着唯一错误的是正确的解决方案，我只是在解释错误信息。

java类没有默认构造函数
