Question

我想将oldTextView的功能交换为ID为nameAgeLabel的TextView。

＆＃34; nameAgeLabel＆＃34;在View视图之外。它还应该像现在一样动态更改文本，具体取决于当前加载的视图。

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看起来像这样：

  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，主要的问题是我在哪里以及如何更改textview＆＃34; nameAge＆＃34;得到与我现在相同的结果？在我的getView方法不起作用，因为

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

不包含带有ID＆＃34; nameAgeLabel＆＃34;的textView。在onCreate中做这件事并没有多大意义。在我的getView中创建一个新视图也不起作用，因为我不能返回2个视图，另外我得到一个＆＃34; android-requestlayout-improperly ..：＆＃34;消息。

非常感谢。

编辑：类名+构造函数

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;
}
}

Answer 1

由于您的描述不完整，我尝试猜测。

为您从SwipeFrameLayout传递TextView的{{1}}创建适配器。在构造函数中或单独的方法。

像

这样的东西

Activity

在cardView之外的TextView
