android.content.res.Resources$NotFoundException: String resource ID #0x0
I'm developing an Android app which reads data from MySQL database and I faced this error. I have this XML layout:
<?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:
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:

I don't know how to fix this error.
Answer
Change
dateTime.setText(app.getTotalDl());
To
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.
I guess app.getTotalDl() returns an int. You need to specifically tell setText to set it to the String value of this int.
