我对android中的EventBus和RxJava之间的区别感到困惑.我需要为我的问题实现其中一个关于在完成一些更改时通知某些组件的问题,以便他们可以更新其状态.
另外,我读到EventsBus已经被RxJava弃用了,我不知道这些信息是否属实.

我尝试运行项目时遇到此错误:

错误:任务':app:transformClassesWithJarMergingForDebug'的执行失败.com.android.build.api.transform.TransformException:java.util.zip.ZipException:重复条目:com/google/android/gms/location/places/zzj.class

这是我正在使用的build.gradle文件:

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'io.realm:realm-gradle-plugin:0.89.1'
    }
}
apply plugin: "com.android.library"
apply plugin: "realm-android"

repositories {
    jcenter()
}

android {
    compileSdkVersion 23
    buildToolsVersion '23.0.3'

    defaultConfig {
        minSdkVersion 15
        targetSdkVersion 22
    }

    buildTypes {
        debug {
            minifyEnabled false
        }
        release {
            minifyEnabled false
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile "com.android.support:appcompat-v7:23.1.1"
    compile "com.android.support:cardview-v7:23.1.1"
    compile "com.android.support:recyclerview-v7:23.1.1"
    compile "com.android.support:design:23.1.1"
    compile "com.squareup.okhttp3:okhttp:3.1.2"
    compile ('com.facebook.android:facebook-android-sdk:4.9.0')
        { exclude group: 'com.android.support' }
    compile ('com.googlecode.libphonenumber:libphonenumber:7.2.2') …

我正在使用启动IntentService的BraodCastReceiver.Everythings看起来很好用,但是我得到了这个错误,我不知道它的来源:

这是我的BrodcastReceiver类:

public class MyReceiver extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals("com.test.intent.action.LINE_ITEM_ADDED")) {
            Intent i = new Intent(context, MyIntentService.class);
            context.startService(i);
        }
    }
}

这是我的IntentService类:

public class MyIntentService extends IntentService { …

当我使用片段时,我没有在ActionBar中获得菜单.尽管执行了onCreateOptionsMenu()方法,但我不知道代码的问题在哪里.这是我正在使用的代码:

public class LesAvis extends Fragment {

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
    setHasOptionsMenu(true);
    View rootView = inflater.inflate(R.layout.avis, container,false);
    ListView listeAvis = (ListView) rootView.findViewById(R.id.listView);
    return rootView;

}

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    inflater.inflate(R.menu.my_menu, menu);
    super.onCreateOptionsMenu(menu,inflater);
}

}

但是,当我使用这部分代码来实现onCreateOptionsMenu()方法时,我得到了我想要的东西(我的操作栏中的菜单):

@Override
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) {
    menu.add("Compte")
    .setIcon(R.drawable.ic_compte)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    menu.add("Compte")
    .setIcon(R.drawable.ic_historique)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
    menu.add("Compte")
    .setIcon(R.drawable.ic_param)
    .setShowAsAction(MenuItem.SHOW_AS_ACTION_ALWAYS);
}
