TextView以外的CardView

Question

我想將oldTextView的功能交換到ID爲nameAgeLabel的TextView。

「nameAgeLabel」位於View視圖之外。 它也應該像現在一樣動態地改變文本，具體取決於當前加載的視圖。

public View getView(final int position, View View, ViewGroup parent) { 


    Log.d("position:",String.valueOf(position)); 
    Log.d("laenge user id",String.valueOf(userIds.size())); 

    String currentUserId = userIds.get(position); 
    LayoutInflater inflater = (LayoutInflater)context.getSystemService 
      (Context.LAYOUT_INFLATER_SERVICE); 

View view = inflater.inflate(R.layout.content_single_mode_vc, parent, false); 

    ImageView imageView = (ImageView) view.findViewById(R.id.offer_image); 
    Bitmap image = userImages.get(currentUserId); 
    imageView.setImageBitmap(image); 


TextView oldTextView= (TextView) view.findViewById(R.id.textView2); 
oldTextView.setText(userNames.get(currentUserId)); 
    //works fine 

    return view; 
} 

我的onCreate看起來是這樣的：

protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.activity_single_mode_vc); 
    TextView nameAge = (TextView) findViewById(R.id.nameAgeLabel); 

    updateImage(); 
    //(thats another method) 

}

所以，主要的問題是在哪裏和我如何必須改變textview「nameAge」才能得到與我現在一樣的結果？在我的getView方法不工作，因爲

TextView nameAge= (TextView) view.findViewById(R.id.nameAgeLabel) 

不包括ID爲「nameAgeLabel」的textView。在onCreate中做這件事並沒有多大意義。 在我的getView中創建一個新的視圖也不起作用，因爲我不能返回2個視圖，另外我得到一個「android-requestlayout-incorrectly ..：」消息。

非常感謝。

編輯：類名+構造

public class SwipeDeckAdapter extends BaseAdapter { 
[...] 
public SwipeDeckAdapter(LinkedList<String> data, Context context, LinkedList<String> userIds, Hashtable<String,String> userNames, Hashtable<String,String> userHashtags, Hashtable<String,Bitmap> userImages, Hashtable<String,ArrayList<String>> userAccepted) { 
    this.data = data; 
    this.context = context; 
    this.userIds = userIds; 
    this.userNames = userNames; 
    this.userHashtags = userHashtags; 
    this.userImages = userImages; 
    this.userAccepted = userAccepted; 
} 
}

由於你的描述是不完整的，我嘗試猜測。

爲SwipeFrameLayout創建一個適配器，您可以從Activity中通過TextView。無論是在構造函數還是單獨的方法。

public class CustomSwipeDeckAdapter extends SwipeDeckAdapter { 

    private AppCompatTextView mNameAgeLabel; 

    public SwipeDeckAdapter(List<String> data, Context context, AppCompatTextView textview) { 
     mNameAgeLabel = textView; 
     […] 
    } 

    public View getView(final int position, View View, ViewGroup parent) { 
     […] 
     mNameAgeLabel.setText(); 
    }
