android.content.res.Resources$NotFoundException: ID de recurso de cadena #0x0
Estoy desarrollando una aplicación para Android que lee datos de la base de datos MySQL y me encontré con este error. Tengo este diseño XML:
<?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>
Y este es mi archivo Java:
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;
}
}

No sé cómo solucionar este error.
Aceptado
Cambiar
dateTime.setText(app.getTotalDl());
A
dateTime.setText(String.valueOf(app.getTotalDl()));
Hay diferentes versiones de setText: una toma una cadena y la otra una identificación de recurso int. Si le pasa un número entero, intentará buscar la identificación del recurso de cadena correspondiente, que no puede encontrar, lo cual es su error.
Supongo que app.getTotalDl()devuelve un int. Debe indicar específicamente setTextque se establezca en el valor de cadena de este int.
setText (int resid) vs setText (texto CharSequence)
Reemplazar
dateTime.setText(app.getTotalDl());
Con
dateTime.setText(""+app.getTotalDl());
Si obtenemos el valor como inty lo configuramos en String, se produce el error. PFB mi solución,
Textview = tv_property_count;
int property_id;
tv_property_count.setText(String.valueOf(property_id));
