【问题描述】:
向其他人发送聊天时出错。
java.lang.IllegalArgumentException: Response must include generic type (e.g., Response<String>)
for method APIService.sendnotif

类接口ApiService
public interface APIService {
@Headers({
"Content-Type:application/json",
"Authorization:key=Lhghhkvhvhffgv"
})
@POST("fcm/send")
Call<Response> sendnotif(@Body Pengirim body);
}
sendnotif.class apiService.sendnotif 行中的错误 必须在此处包含泛型类型。你能向我解释一下进行泛型改造吗?
private void sendnotif(final String hisUid, final String name, final String pesan) {
DatabaseReference alltoken = FirebaseDatabase.getInstance().getReference("Tokens");
Query query = alltoken.orderByKey().equalTo(hisUid);
query.addValueEventListener(new ValueEventListener() {
@Override
public void onDataChange(@NonNull DataSnapshot dataSnapshot) {
for(DataSnapshot ds: dataSnapshot.getChildren()){
Tokenclass tokenclass = ds.getValue(Tokenclass.class);
Datanotif data = new Datanotif(myUid, name+":"+pesan, "Pesan Baru", hisUid, R.drawable.ic_usr_name);
Pengirim pengirim = new Pengirim(data, tokenclass.getToken());
apiService.sendnotif(pengirim)
.enqueue(new Callback<Response>() {
@Override
public void onResponse(Call<Response> call, Response<Response> response) {
Toast.makeText(ChatAct.this, ""+response.message(), Toast.LENGTH_SHORT).show();
}
@Override
public void onFailure(Call<Response> call, Throwable t) {
}
});
}
}
@Override
public void onCancelled(@NonNull DatabaseError databaseError) {
}
});
}
apiService.sendnotif(pengirim) 中的错误
请帮帮我,它会使应用程序强制关闭
