网上找到了两个解决方案：
https://github.com/beefe/react-native-picker/issues/289
https://github.com/beefe/react-native-picker/issues/294
综合整理后，解决方案如下：
1.文件./android/settings.gradle中末尾添加：
include ':react-native-picker'
project(':react-native-picker').projectDir = new File(rootProject.projectDir, '../node_modules/react-native-picker/android')
2.文件./android/app/build.gradle的dependencies内添加（注意其他行有逗号","，最后一行没逗号）：
...
dependencies {
...
compile project(':react-native-picker')
}
...
3.文件./android/app/src/main/java/com/xxx/xxx/MainApplication.java中添加：
import com.beefe.picker.PickerViewPackage;
...
@Override
protected ListgetPackages() {
return Arrays.asList(
new MainReactPackage(),
...
new PickerViewPackage()
);
}
...
4.重新运行项目就OK了。
