解决方法

首先来看我这个项目build.gradle中的依赖：

compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.google.code.gson:gson:2.6.1'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'io.reactivex:rxjava:1.1.0'
compile 'io.reactivex:rxandroid:1.1.0'
//    compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'

compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'
compile 'com.squareup.retrofit2:retrofit:2.1.0'

大家发现了没有，最后2个依赖版本不一致，刚刚上面所报的错误就是因为这个版本不一致造成的，所以我们的解决方案就是：让他们所依赖的版本一致，就可以了

把compile 'com.squareup.retrofit2:adapter-rxjava:2.0.0-beta4'依赖换成
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'就可以了

这个版本不一致出现错误，可能是因为它版本不同，里面的有些API不一致造成的，改过之后的依赖

compile 'com.android.support:appcompat-v7:23.1.0'
compile 'com.android.support:design:23.1.0'
compile 'com.squareup.retrofit2:converter-gson:2.0.2'
compile 'com.google.code.gson:gson:2.6.1'
compile 'com.squareup.okhttp3:okhttp:3.2.0'
compile 'io.reactivex:rxjava:1.1.0'
compile 'io.reactivex:rxandroid:1.1.0'
compile 'com.squareup.retrofit2:adapter-rxjava:2.1.0'
compile 'com.squareup.retrofit2:retrofit:2.1.0'

这样运行项目，就OK了，问题解决
