如何設置recyclerView適配器？

Question

所以，我不知道該怎麼做。我想獲取jsonData並使用來自同一個Activtiy的這些數據設置一個適配器。這甚至有可能嗎？如果是，我應該怎麼做，因爲它會因爲「下載」延遲而一直崩潰。適配器想要設置比獲取數據的時間早，因爲它是空數組。

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); 
}

請務必從調用webservice的

請了遵循以下讓你得到關於如何實現它的概述適配器設置你的數據後，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 

      } 

       } 
      }
