首先，我阅读了与此问题相关的所有答案，但我没有解决此错误。我的程序正在运行，但非常滞后和缓慢。我尝试使用较小的图片并使用asynctask但我的问题仍在继续。这是我的代码。我试过手机和模拟器
public class MainActivity extends AppCompatActivity {
RecyclerView recyclerView;
NotificationManager manager;
public Veri veri,veri1;
int x= 0;
private Timer autoUpdate;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
veri1 = new Veri();
x=veri1.getList().size();
recyclerView= (RecyclerView) findViewById(R.id.my_recycler_view);
StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder().permitAll().build();
StrictMode.setThreadPolicy(policy);
manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
onResume();
new AsyncCaller().execute();
}
@Override
protected void onStart() {
super.onStart();
}
////////////////////////////////////////////
private class AsyncCaller extends AsyncTask<Void, Void, Void>

super.onPreExecute();
}
@Override

autoUpdate.schedule(new TimerTask() {
@Override
public void run() {
runOnUiThread(new Runnable() {
public void run() {

});
}
}, 0, 60000);
return null;

@Override

super.onPostExecute(result);

// your logic here
RecyclerAdapter adapter=new RecyclerAdapter(this);
recyclerView.setAdapter(adapter);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
veri = new Veri();
int a = veri.getList().size();
if(a!=x){
generateNotification(MainActivity.this,"Listede Degisim Var");
}
x=a;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {

return true;
default:
return super.onOptionsItemSelected(item);
}
}
private void LocationFound() {
Intent i = new Intent(MainActivity.this, LocationFound.class);
startActivity(i);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.activity_main_actions, menu);
return super.onCreateOptionsMenu(menu);
}
private void generateNotification(Context context,String message){
int notificationId = 001;
Intent viewIntent = new Intent(context, MainActivity.class);
PendingIntent viewPendingIntent =
PendingIntent.getActivity(context, 0, viewIntent, 0);
NotificationCompat.Builder notificationBuilder =
(NotificationCompat.Builder) new NotificationCompat.Builder(this)
.setSmallIcon(R.drawable.dikat)
.setContentTitle("Bildirim")
.setContentText(message)
.setContentIntent(viewPendingIntent)
.setAutoCancel(true)
.setSound(Uri.parse("android.resource://"
+ context.getPackageName() + "/" + R.raw.bildirim))
.setVibrate(new long[] { 1000, 1000, 1000, 1000, 1000 });
NotificationManagerCompat notificationManager =
NotificationManagerCompat.from(context);
notificationManager.notify(notificationId, notificationBuilder.build());
}
}
这是我的数据类
public class Veri extends ActionBarActivity {
NotificationManager manager;
Notification myNotication;
String ip, db, un, passwords;
Connection connect,conn;
PreparedStatement stmt;
ResultSet rs;
TextView tv;
int position1=0;

ArrayList<String> data = new ArrayList<String>();
ArrayList<String> data2 = new ArrayList<String>();

connect = CONN(un, passwords, db, ip);
String query = "SELECT Adsoyad,(DATEPART(hour, BeklemeSuresi) * 3600) + (DATEPART(minute, BeklemeSuresi) * 60) + DATEPART(second, BeklemeSuresi) as SecondsFromMidnight,Durum FROM [dbo].[IslemiDevamEdenHasta] (1)";
try {
// connect = CONN(un, passwords, db, ip);
stmt = connect.prepareStatement(query);
rs = stmt.executeQuery();
while (rs.next()) {
int b = (int)rs.getInt("SecondsFromMidnight")/60;
if(b>50) {
String id = rs.getString("Adsoyad");
String id2 = rs.getString("Durum");
String full = id + " " + id2;
String a = "" + b;
data.add(full);
data2.add(a);
}
}
} catch (SQLException e) {
e.printStackTrace();
}
}
public ArrayList<String> getList() {
return data;
}
public ArrayList<String> getList2() {
return data2;
}
@SuppressLint("NewApi")

}
这是我的回收者类
public class RecyclerAdapter extends RecyclerView.Adapter<RecyclerViewHolder> {
public Veri veri = new Veri();
int sayi=0;
ArrayList<String> liste = veri.getList();
ArrayList<String> liste2 = veri.getList2();
static ArrayList<String> liste3 = new ArrayList<String>() ;
Context context;
LayoutInflater inflater;
public RecyclerAdapter(Context context) {
this.context=context;
inflater=LayoutInflater.from(context);
}
@Override
public RecyclerViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View v=inflater.inflate(R.layout.item_list, parent, false);
RecyclerViewHolder viewHolder=new RecyclerViewHolder(v);
return viewHolder;
}
@Override
public void onBindViewHolder(RecyclerViewHolder holder, int position) {
liste3.add("a");
sayi = 0;
for (int j = 0; j < liste3.size(); j++) {
if (liste3.get(j).equals(liste.get(position))) {
sayi++;
}
if (sayi == 0) {
holder.tv1.setText(liste.get(position));
holder.tv2.setText(liste2.get(position));
holder.imageView.setOnClickListener(clickListener);
holder.imageView.setTag(holder);
} else {
holder.tv1.setText(liste.get(position));
holder.tv2.setText(liste2.get(position));
holder.imageView.setOnClickListener(clickListener);
holder.imageView.setImageResource(R.drawable.ic_checkin);
}
}
}
View.OnClickListener clickListener=new View.OnClickListener() {
@Override
public void onClick(View v) {
RecyclerViewHolder vholder = (RecyclerViewHolder) v.getTag();
int position = vholder.getPosition();
//Toast.makeText(context,"This is position "+position,Toast.LENGTH_LONG ).show();
vholder.imageView.setImageResource(R.drawable.ic_checkin);
liste3.add(liste.get(position));
}
};
@Override
