android.content.res.Resources $ NotFoundException：字符串资源ID＃0x0

145

我正在开发一个Android应用，该应用从MySQL数据库读取数据，但遇到了此错误。我有这个XML布局：

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:orientation="vertical" > 


        <TextView android:id="@+id/wardNumber" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:layout_marginLeft="3dp" 
            android:text="Ward Number" 
            android:textSize="22dp"/> 


        <TextView android:id="@+id/dateTime" 
            android:layout_width="wrap_content" 
            android:layout_height="wrap_content" 
            android:layout_below="@id/wardNumber" 
            android:layout_alignParentRight="true" 
            android:layout_marginRight="3dp" 
            android:text="Date-Time" />

        <TextView
            android:id="@+id/name"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignBaseline="@+id/dateTime"
            android:layout_alignBottom="@+id/dateTime"
            android:layout_alignLeft="@+id/wardNumber"
            android:layout_marginLeft="3dp" 
            android:text="Name" />

</RelativeLayout>

这是我的Java文件：

public ApplicationAdapter(Context context, List<Application> items) {
    super(context, R.layout.app_custom_list, items);
    this.items = items;
}

@Override
public int getCount() {
    return items.size();
}

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    View v = convertView;

    if(v == null) {
        LayoutInflater li = LayoutInflater.from(getContext());
        v = li.inflate(R.layout.app_custom_list, null);            
    }

    Application app = items.get(position);

    if(app != null) {
      //  ImageView icon = (ImageView)v.findViewById(R.id.appIcon);
        TextView wardNumber = (TextView)v.findViewById(R.id.wardNumber);
        TextView name = (TextView)v.findViewById(R.id.name);
      //  LinearLayout ratingCntr = (LinearLayout)v.findViewById(R.id.ratingCntr);
        TextView dateTime = (TextView)v.findViewById(R.id.dateTime);

  //      if(icon != null) {
  //          Resources res = getContext().getResources();
   //         String sIcon = "com.sj.jsondemo:drawable/" + app.getIcon();
   //         icon.setImageDrawable(res.getDrawable(res.getIdentifier(sIcon, null, null)));
   //     }

        if(wardNumber != null) wardNumber.setText(app.getTitle());

        if(name != null) name.setText(app.getTitle());

        if(dateTime != null) {
            dateTime.setText(app.getTotalDl());
          //  NumberFormat nf = NumberFormat.getNumberInstance();
          //  dateTime.setText(nf.format(app.getTotalDl())+" dl");            
        }


    }

    return v;
}
}

调用此Activity时，我收到以下错误消息：

更改

dateTime.setText(app.getTotalDl());

至

dateTime.setText(String.valueOf(app.getTotalDl()));

有不同的版本setText-一种采用字符串，一种采用int资源ID。如果将其传递给整数，它将尝试寻找相应的字符串资源ID-找不到它，这是您的错误。

我想app.getTotalDl()返回一个整数。您需要专门告诉setText将其设置为此int的String值。

setText（int resid）与setText（CharSequence文本）

setText（int resId）甚至都没有附加Javadoc。他们真的应该给这个名字起一个单独的名字-显然是这里的常见滥用。因此，指定resId会将TextView的文本设置为其他资源的文本吗？

更换

dateTime.setText(app.getTotalDl());

用

dateTime.setText(""+app.getTotalDl());

是工作，但是我认为这不是合适的方式。@KenWolf的答案是正确和专业的方法。

如果获得值as int并将其设置为String，则会发生错误。PFB我的解决方案，

Textview = tv_property_count;
int property_id;
tv_property_count.setText(String.valueOf(property_id));

当您尝试以Edittext或设置文本时，textview应仅传递字符串格式。

dateTime.setText(app.getTotalDl());

至

dateTime.setText(String.valueOf(app.getTotalDl()));

settext的评估值为整数，因此它去查看了附加到它的资源，但是找不到它，您想要设置文本，因此它应该是字符串，因此通过附加将integer转换为string .toStringe 或String.valueOf(int)将解决您的问题！

如果获取int中的值，则必须使用字符串，这会引发错误

之前

  holder.villageName.setText(villageModelList.get(position).getVillageName());
    holder.villageCount.setText(villageModelList.get(position).getPeopleCount());
    holder.peopleCount.setText(villageModelList.get(position).getPeopleCount());

后

  holder.villageName.setText(villageModelList.get(position).getVillageName());
    holder.villageCount.setText(String.valueOf(villageModelList.get(position).getPeopleCount()));
    holder.peopleCount.setText(String.valueOf(villageModelList.get(position).getPeopleCount()));

您可以通过添加String.valueOf解决错误
