我正试图在服务器点击按钮时执行注销操作，但每当我点击Logout时，它就会卡在SweetAlertDialogBox上。
当我调试我的代码时，调试器调试代码直到行：“client.newCall（request）.enqueue（new callback（）{”在logoutservice（）内部，然后在此之后转到“String message” “它实际上终止了。它会在失败和onResponse方法上跳过它们
Logcat中没有提到错误
这是我的按钮点击代码： -
btnLogout = itemBuilder.setContentView(logoutIcon).build();
btnLogout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
AlertDialog.Builder alertDialog = new AlertDialog.Builder(AlarmActivity.this);
alertDialog.setMessage("Are you sure you want to log out?");
alertDialog.setCancelable(false);
alertDialog.create();
alertDialog.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
if (networkUtil.isConnected()) {
logoutService();
} else {
AlertDialog.Builder alertbox = new AlertDialog.Builder(AlarmActivity.this);
alertbox.setMessage("No network connection, Please try after some time");
alertbox.create();
alertbox.setCancelable(false);
alertbox.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
dialog.cancel();
}
});
alertbox.show();
}
}
}).setNegativeButton("No", null).show();
}
});
这是我的退出和退出服务方法： -
public void logout() {
Intent i = new Intent(this, AlertDialogActivity.class);
pendingIntent = PendingIntent.getActivity(AlarmActivity.this,
12345, i, PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager manager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
manager.cancel(pendingIntent);
stopService(new Intent(AlarmActivity.this, LocationTracker.class));
System.exit(0);
}
private void logoutService() {
OkHttpClient client = new OkHttpClient();
String requestURL = String.format(getResources().getString(R.string.service_logout));
JSONObject jsonrequest = new JSONObject();
try {
Date today = Calendar.getInstance().getTime();
SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd HH-mm-ss");
jsonrequest.accumulate("mobNo", pref.getValueFromSharePref("mobileno"));
jsonrequest.accumulate("empAuthKey", pref.getValueFromSharePref("authKey"));
jsonrequest.accumulate("logoutTime", simpleDateFormat.format(today));
jsonrequest.accumulate("lat", "" + locationInfo.lastLat);
jsonrequest.accumulate("lon", "" + locationInfo.lastLong);
} catch (Exception e) {
e.printStackTrace();
}
final RequestBody body = RequestBody.create(MediaType.parse("application/json; charset=utf-8"), jsonrequest.toString());
Request request = new Request.Builder()
.url(requestURL)
.post(body).build();
final SweetAlertDialog pDialog = new SweetAlertDialog(AlarmActivity.this, cn.pedant.SweetAlert.SweetAlertDialog.PROGRESS_TYPE);
pDialog.getProgressHelper().setBarColor(Color.parseColor("#A5DC86"));
pDialog.setTitleText("Loading, Please wait ...");
pDialog.setCancelable(false);
pDialog.show();
client.newCall(request).enqueue(new Callback() {
String status,message;
Handler handler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
if (msg.what == 1) {
Toast.makeText(getBaseContext(), "" + message, Toast.LENGTH_SHORT).show();
logout();
} else if (msg.what == 0) {
Toast.makeText(getBaseContext(), "" + message, Toast.LENGTH_SHORT).show();
} else if (msg.what == -1) {
Toast.makeText(getBaseContext(), "" + message, Toast.LENGTH_SHORT).show();
} else if (msg.what == 2) {
Toast.makeText(AlarmActivity.this, "System Error Please try again...", Toast.LENGTH_LONG).show();
}
return false;
}
});
@Override
public void onFailure(Call call, IOException e) {
if (pDialog.isShowing()) pDialog.dismiss();
handler.sendEmptyMessage(2);
}
@Override
public void onResponse(Call call, Response response) throws IOException {
if (response.isSuccessful()) {
String responseString = response.body().string();
try {
JSONObject jsonResponse = new JSONObject(responseString);
status = jsonResponse.getString("status");
message = jsonResponse.getString("message");
if (status.equals("success")) {
if (pDialog.isShowing()) pDialog.dismiss();
handler.sendEmptyMessage(1);
response.body().close();
} else if (status.equals("failure")) {
if (pDialog.isShowing()) pDialog.dismiss();
handler.sendEmptyMessage(-1);
response.body().close();
} else if (status.equals("error")) {
if (pDialog.isShowing()) pDialog.dismiss();
handler.sendEmptyMessage(0);
response.body().close();
}
} catch (Exception e) {
e.printStackTrace();
if (pDialog.isShowing()) pDialog.dismiss();
handler.sendEmptyMessage(2);
response.body().close();
}
}
}
});
}
请帮我解决这个问题，Logcat没有错误..
答案 0 :(得分：1)
您可能在Handler内使用onResponse在UI线程中执行某些操作，因此您还应该在handleMessage中解除SweetAlertDialog
Handler handler = new Handler(new Handler.Callback() {
@Override
public boolean handleMessage(Message msg) {
//...
if (pDialog.isShowing()) pDialog.dismiss();
return false;
}
});
