機器人回收視圖和旋轉

IM的一個問題，我需要一些幫助，回收者看來，機器人回收視圖和旋轉

所以我有這樣的回收觀點： enter image description here

但是，當我旋轉設備，回收商永遠不會到來回.. 的事情是，即時通訊呼籲onCreate方法異步任務，所以即使我旋轉設備時，onCreate方法將被再次調用，並重新填充回收的觀點，但在這種情況下，那不會發生。我怎樣才能解決這個問題？

當我旋轉設備我得到這樣的結果： enter image description here

這是我的活動代碼：

import android.os.AsyncTask; 
import android.os.Bundle; 
import android.os.StrictMode; 
import android.support.v7.app.AppCompatActivity; 
import android.support.v7.widget.DefaultItemAnimator; 
import android.support.v7.widget.LinearLayoutManager; 
import android.support.v7.widget.RecyclerView;; 

/**

public class MainFeed extends AppCompatActivity { 

    private getData getData = new getData(); 
    private RecyclerView recyclerView; 
    private LinearLayoutManager linearLayoutManager; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main_feed); 

     StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build(); 
     StrictMode.setThreadPolicy(policy); 

     recyclerView = (RecyclerView) findViewById(R.id.rvFeed); 
     recyclerView.setHasFixedSize(false); 
     recyclerView.setItemAnimator(new DefaultItemAnimator()); 

     linearLayoutManager = new LinearLayoutManager(MainFeed.this); 
     recyclerView.setLayoutManager(linearLayoutManager); 

     new fetchFeed().execute(); 

    } 



    class fetchFeed extends AsyncTask<Void, Void, Void> { 


     @Override 
     protected void onPreExecute() { 


     } 

     @Override 
     protected Void doInBackground(Void... params) { 
      getData.getPosts("http://**.**.***.***:81/chefeBook/feed.php"); 
      return null; 
     } 

     @Override 
     protected void onPostExecute(Void result) { 
      feedRecyclerAdapter feedRecyclerAdapter = new feedRecyclerAdapter(MainFeed.this, getData.resultList, "http://**.***.***.***:81/chefeBook/feedImages/"); 
      recyclerView.setAdapter(feedRecyclerAdapter); 
     } 

    } 


}

這是我的適配器代碼：

import android.content.Context; 
import android.support.v7.widget.RecyclerView; 
import android.util.Log; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup;

import android.widget.TextView; 

import com.squareup.picasso.Picasso; 

import java.util.List; 

/**

public class feedRecyclerAdapter extends RecyclerView.Adapter<feedRecyclerAdapter.ViewHolder> { 

    private List<FeedPosts> resultFeedPost; 
    private LayoutInflater context; 
    private String imageFolder; 

    /* Constructor */ 
    public feedRecyclerAdapter(Context context, List<FeedPosts> resultFeedPost, String imageFolder) { 

     this.context = LayoutInflater.from(context); 
     this.resultFeedPost = resultFeedPost; 
     this.imageFolder = imageFolder; 

    } 


    @Override 
    public feedRecyclerAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) { 

     View v = context.inflate(R.layout.main_feed_item, null); 
     return new ViewHolder(v); 

    } 

    @Override 
    public void onBindViewHolder(feedRecyclerAdapter.ViewHolder holder, int position) { 


     FeedPosts feedPosts = resultFeedPost.get(position); 

     holder.rvTitle.setText(feedPosts.getTitle()); 
     holder.rvLikes.setText(feedPosts.getLikes() + " Likes"); 
     Picasso.with(holder.rvImage.getContext()).load(imageFolder + feedPosts.getImage()).fit().centerCrop().into(holder.rvImage); 



    } 

    @Override 
    public int getItemCount() { 
     return resultFeedPost == null ? 0 : resultFeedPost.size(); 
    } 

    public class ViewHolder extends RecyclerView.ViewHolder { 

     ImageView rvImage; 
     TextView rvTitle; 
     TextView rvLikes; 

     public ViewHolder(View itemView) { 
      super(itemView); 

      rvImage = (ImageView) itemView.findViewById(R.id.feedImage); 
      rvTitle = (TextView) itemView.findViewById(R.id.feedTitle); 
      rvLikes = (TextView) itemView.findViewById(R.id.feedLikes); 

     } 

    } 


}

這是我的類，可以幫助我把數據存儲列表

裏面

這是我的JSON結果：（其不相關的問題，但belogs它，因此..）

如果您的縱向和橫向佈局會是一樣的，那麼能否請您簡單地爲您MainFeed活動清單文件中加入這一行試試。

android:configChanges="orientation|keyboardHidden|screenSize"

希望這會對你有用。

這不適合我，因爲我有一些在景觀佈局的變化，在肖像圖像有一個特定的高度值，但在landscpae它match_parent，但無論如何感謝 – user3000019

以及可以處理，所有你有要做的就是動態計算高度寬度，並相應地爲你的圖像視圖設置佈局參數。所以基本上你的ImageView的高度將按照如下動態計算。如果（screenWidth

嘿感謝，但即時通訊試圖找到一個解決方案，在那裏我可以節省回收視圖，並再次顯示在屏幕上旋轉 – user3000019
