android.content.res.Resources$NotFoundException: 字符串資源 ID #0x0

Question

我正在開發一個從 MySQL 數據庫讀取數據的 Android 應用程序，但我遇到了這個錯誤。 我有這個 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> 

這是我的 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;
}
}

調用此活動時，我收到此錯誤消息：

我不知道如何解決這個錯誤。

Answer 1

改變

dateTime.setText(app.getTotalDl());

到

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

setText有不同的版本——一種采用 String ，一種采用 int 資源 ID。 如果您向它傳遞一個整數，它將嘗試查找相應的字符串資源 ID - 它找不到，這是您的錯誤。

我猜app.getTotalDl()返回一個 int。 您需要專門告訴setText將其設置為該 int 的 String 值。

setText (int resid) vs setText (CharSequence text)

Answer 2

代替

dateTime.setText(app.getTotalDl());

和

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

Answer 3

如果我們將值設為int並將其設置為String ，則會發生錯誤。 PFB我的解決方案，

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

Answer 4

當您嘗試在Edittext或textview設置文本時，您應該只傳遞字符串格式。

dateTime.setText(app.getTotalDl());

到

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

Answer 5

settext 的評估值是整數，因此它會查看附加到它的資源，但未找到，您想設置文本，因此它應該是字符串，因此通過附加.toStringe或String.valueOf(int)將整數轉換為字符串解決你的問題！

Answer 6

你能行的。 這是一個簡單的方法。

txtTopicNo.setText(10+"");

Answer 7

如果你得到 int 中的值，你必須使用 string 因為它拋出錯誤

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()));

您可以通過添加String.valueOf來解決錯誤

Answer 8

如果你使用 Kotlin

dateTime.setText(
    app.getTotalDl().toString()
)

如果問題仍然存在並且您正在使用data binding以防萬一，請重新檢查您的android:text屬性。
