android.content.res.Resources$NotFoundException: String resource ID #0x0
提问by user2881604
I'm developing an Android app which reads data from MySQL database and I faced this error. I have this XML layout:
我正在开发一个从 MySQL 数据库读取数据的 Android 应用程序，但我遇到了这个错误。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>
And this is the my Java file:
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;
}
}
When this Activity is called, I receive this error message:

Change
改变
dateTime.setText(app.getTotalDl());
To
到
dateTime.setText(String.valueOf(app.getTotalDl()));
There are different versions of setText- one takes a String and one takes an int resource id. If you pass it an integer it will try to look for the corresponding string resource id - which it can't find, which is your error.
有不同的版本setText- 一种采用 String ，一种采用 int 资源 ID。如果您向它传递一个整数，它将尝试查找相应的字符串资源 ID - 它找不到，这是您的错误。
I guess app.getTotalDl()returns an int. You need to specifically tell setTextto set it to the String value of this int.
我想app.getTotalDl()返回一个整数。您需要专门告诉setText将其设置为该 int 的 String 值。

Replace
代替
dateTime.setText(app.getTotalDl());
With
和
dateTime.setText(""+app.getTotalDl());

When you try to set text in Edittextor textviewyou
should pass only String format.
当您尝试在Edittextor 中设置文本时，textview您应该只传递字符串格式。
dateTime.setText(app.getTotalDl());
to
到
dateTime.setText(String.valueOf(app.getTotalDl()));

The evaluated value for settext was integer so it went to see a resource attached to it but it was not found, you wanted to set text so it should be string so convert integer into string by attaching .toStringeor String.valueOf(int)will solve your problem!
settext 的评估值是整数，因此它会查看附加到它的资源，但未找到，您想设置文本，因此它应该是字符串，因此通过附加将整数转换为字符串，.toStringe否则String.valueOf(int)将解决您的问题！

If we get the value as intand we set it to String, the error occurs. PFB my solution,
如果我们得到值为 asint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));
回答by sanjay
if you get the values in int you have to use string for that it is throwing the error
如果你得到 int 中的值，你必须使用 string 因为它抛出错误
before
前
holder.villageName.setText(villageModelList.get(position).getVillageName());
holder.villageCount.setText(villageModelList.get(position).getPeopleCount());
holder.peopleCount.setText(villageModelList.get(position).getPeopleCount());
after
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()));
you can solve the error by adding the String.valueOf
您可以通过添加String.valueOf来解决错误
