如何设置recyclerView适配器？

Question

所以，我不知道该怎么做。我想获取jsonData并使用来自同一个Activtiy的这些数据设置一个适配器。这甚至有可能吗？如果是，我应该怎么做，因为它会因为“下载”延迟而一直崩溃。适配器想要设置比获取数据的时间早，因为它是空数组。

private SzabadEuMusorok[] mSzabadEuMusoroks; 

@InjectView(R.id.archivumReyclerView) 
RecyclerView mRecyclerView; 

@Override 
protected void onCreate(@Nullable Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_archivum); 
    ButterKnife.inject(this); 

    setArray(); 

    CollectionsAdapter adapter = new CollectionsAdapter(this, mSzabadEuMusoroks); 
    mRecyclerView.setAdapter(adapter); 

    RecyclerView.LayoutManager layoutManager = new LinearLayoutManager(this); 
    mRecyclerView.setLayoutManager(layoutManager); 

    mRecyclerView.setHasFixedSize(true); 
}

请务必从调用webservice的

请了遵循以下让你得到关于如何实现它的概述适配器设置你的数据后，才：

 public class MainActivity extends Activity implements OnClickListener { 
      private SzabadEuMusorok[] mSzabadEuMusoroks; 

      @InjectView(R.id.archivumReyclerView) 
      RecyclerView mRecyclerView; 
      RecyclerView.LayoutManager layoutManager ; 
      @Override 
      protected void onCreate(@Nullable Bundle savedInstanceState) { 
       super.onCreate(savedInstanceState); 
       setContentView(R.layout.activity_archivum); 
       ButterKnife.inject(this); 

       setArray(); 


       layoutManager = new LinearLayoutManager(this); 

     new LongOperation().execute("");//call your webservice 
      } 



       private class LongOperation extends AsyncTask<String, Void, String> { 

        @Override 
        protected String doInBackground(String... params) { 
         for (int i = 0; i < 5; i++) { 
          try { 

      //call your webservice here 
          } catch (InterruptedException e) { 
           Thread.interrupted(); 
          } 
         } 
         return serviceResult;// this will be passed to onPostExecute 
        } 

        @Override 
        protected void onPostExecute(String result) { 
mRecyclerView.setLayoutManager(layoutManager); 

       mRecyclerView.setHasFixedSize(true); 
        CollectionsAdapter adapter = new CollectionsAdapter(this, mSzabadEuMusoroks); 
      mRecyclerView.setAdapter(adapter); //set your adapter using result in webservice called in doinbackground 
        } 

        @Override 
        protected void onPreExecute() { 
      // show a progress dialog 

      } 

       } 
      }
