如何在android中使用EventBus库
我想为一个站点开发安卓应用程序，在这个应用程序中我想使用如何在android中使用EventBus库,android,event-bus,Android,Event Bus,我想为一个站点开发安卓应用程序，在这个应用程序中我想使用okhttpv3和EventBus v3。eventbus库源链接：。 我写了下面的代码，但在运行应用程序时，向我显示FC错误 okHttp\u页面（主要活动）代码： public class okHTTP_Page extends AppCompatActivity { private RecyclerView recycler; private okHTTP_adapter adaper; @Override
okhttpv3EventBus v3我写了下面的代码，但在运行应用程序时，向我显示FC错误
okHttp\u页面（主要活动）代码：
public class okHTTP_Page extends AppCompatActivity {
private RecyclerView recycler;
private okHTTP_adapter adaper;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.ok_http__page);
EventBus.getDefault().register(this);
recycler = (RecyclerView) findViewById(R.id.okHTTP_recycler);
recycler.setHasFixedSize(true);
recycler.setLayoutManager(new LinearLayoutManager(this));
okHTTP_info info = new okHTTP_info();
info.getOkHTTP_info(this);
adaper = new okHTTP_adapter(this);
recycler.setAdapter(adaper);
}
}
public class okHTTP_info {
private Context mContext;
public void getOkHTTP_info(Context context) {
mContext = context;
new getInfo().execute(serverIP.getIP());
}
private class getInfo extends AsyncTask<String, Void, String> {
EventBus bus = EventBus.getDefault();
private String ou_response;
private List<okHTTP_dataProvider> infoModels;
@Override
protected void onPreExecute() {
CustomProcessDialog.createAndShow(mContext);
infoModels = new ArrayList<>();
}
@Override
protected String doInBackground(String... params) {
OkHttpClient client = new OkHttpClient();
RequestBody requestBody = new MultipartBody.Builder()
.addFormDataPart("test", "2")
.addFormDataPart("posts", params[0])
.build();
Request request = new Request.Builder()
.url(serverIP.getIP())
.post(requestBody)
.build();
Response response;
try {
response = client.newCall(request).execute();
ou_response = response.body().string();
response.body().close();
if (ou_response != null) {
try {
JSONObject postObj = new JSONObject(ou_response);
JSONArray postsArray = postObj.getJSONArray("posts");
infoModels = new ArrayList<>();
for (int i = 0; i < postsArray.length(); i++) {
JSONObject postObject = postsArray.getJSONObject(i);
int id = postObject.getInt("id");
String title = postObject.getString("title");
Log.d("Data", "Post id: " + id);
Log.d("Data", "Post title: " + title);
//Use the title and id as per your requirement
infoModels.add(new okHTTP_dataProvider(
postObject.getString("title"),
postObject.getInt("id")));
}
} catch (JSONException e) {
e.printStackTrace();
}
}
} catch (IOException e) {
e.printStackTrace();
}
return ou_response;
}
@Override
protected void onPostExecute(String result) {

if (result != null) {
bus.post(infoModels);

公共类okHTTP\u信息{
私有上下文；
公共无效getOkHTTP_信息（上下文）{
mContext=上下文；
新建getInfo（）.execute（serverIP.getIP（））；
}
私有类getInfo扩展了异步任务{
EventBus=EventBus.getDefault（）；
私有字符串ou_响应；
私有列表信息模型；

您需要添加一个带有@Subscribe注释的方法。该方法还需要采用一个参数，即您正在发布的类型。因此，将此添加到您的
AppCompatActivity@Subscribe
public void subscribeMethod(List infoModels) {
// Do stuff...
}
@Subscribe
public void subscribeMethod(InfoModelsEvent infoModelsEvent) {
// Do stuff...
}
bus.post(new InfoModelsEvent(infoModels));
@Subscribe
public void onEvent(List<okHTTP_dataProvider> infoModels) {
};
@Subscribe
public void onEventMainThread(){
}
