How do you use the Preference to keep data when using SurfaceView?

It would be desirable to maintain data using Preferecnce. But trying to use the method
```
mSettings = getSharedPreferences(APP_PREFERENCES, Context.MODE_PRIVATE);
```
The studio is fighting. getSharedPreferences(APP_PREFERENCES, Context.MODE_PRIVATE);
However, with the use of XML Activity, the studio behaves quietly to recognize this method.
What can we do about it?

getSharedPreferences - it's a class method. Context, activate - the heir of the context, and it can directly trigger this method, and in the context, it needs to be triggered.
```
mSettings = getContext().getSharedPreferences(APP_PREFERENCES, Context.MODE_PRIVATE);
```

If you can identify a structure that requires data to be stored in a file, you can use it. XmlSerializer♪ Example of code:// запись даных в объект var dataInstance = new MyData(); dataInstance.DoubleValue1 = 0.1; dataInstance.DoubleValue2 = 0.2; dataInstance.DoubleList.Add(0.3); dataInstance.DoubleList.Add(0.4); // сохранение в файл using (var stream = new FileStream(@"c:\data\data.xml", FileMode.Create)) { var serializer = new XmlSerializer(typeof(MyData)); serializer.Serialize(stream, dataInstance); } // чтение из файла MyData data; using (var stream = new FileStream(@"c:\data\data.xml", FileMode.Open)) { var serializer = new XmlSerializer(typeof(MyData)); data = serializer.Deserialize(stream) as MyData; } Console.WriteLine(data.DoubleValue1); Console.WriteLine(data.DoubleValue2); Console.WriteLine(data.DoubleList[1]); And in fact, the class with the data is:// Класс, инкапсулирующий данные public class MyData { public Double DoubleValue1 { get; set; } public Double DoubleValue2 { get; set; } public List<Double> DoubleList { get; set; } public MyData() { this.DoubleList = new List<Double>(); } }

I'll risk assuming you need something like this: private $territory; // закрываем прямой доступ снаружи public function getReg() { $db = DB::getInstance(); $query="SELECT ter_address, reg_id FROM t_koatuu_tree where ter_type_id = 0 AND ter_pid <=> NULL"; $result=$db->query($query); if (!$result) {die($db->error);} $reg_id=[]; while($row = $result->fetch_assoc()){ $reg_id[]=$row['reg_id']; } ; return $reg_id; } public function getTerritory (){ if (is_null($this->territory)) { // проверяем есть ли значение, если нет, то получаем его $territory=(int)self::getReg()[mt_rand(0,count(self::getReg())-1)]; $this->territory= $this->clean($this->escape($territory)); } return $this->territory; // возвращаем значение из БД или RAM } public function AutoqualiTowns() { $territory=$this->getTerritory();

First you don't need to get the references from the EditText within your Save() method as you did initially in the method onCreate().public void Save(View view) { String n = name.getText().toString(); String a = address.getText().toString(); String fcn = firstContactName.getText().toString(); String fcpn = firstContactPhoneNumber.getText().toString(); String scn = secondContactName.getText().toString(); String scpn = secondContactPhoneNumber.getText().toString(); SharedPreferences.Editor editor = sharedpreferences.edit(); editor.putString(Name, n); editor.putString(Address, a); editor.putString(FirstContactName, fcn); editor.putString(FirstContactPhoneNumber, fcpn); editor.putString(SecondContactName, scn); editor.putString(SecondContactPhoneNumber, scpn); editor.apply(); } Now after you save the values in preferences when you start your app you must get them the following way, only by looking for the value in the preferences using your assigned key, if there is no you are defining that the value you will add in the TextView it was a String vacìo: @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_my_info); name = (TextView) findViewById(R.id.edit_text_my_name); address = (TextView) findViewById(R.id.edit_text_my_address); firstContactName = (TextView) findViewById(R.id.edit_text_first_contact_name); firstContactPhoneNumber = (TextView) findViewById(R.id.edit_text_first_contact_phone); secondContactName = (TextView) findViewById(R.id.edit_text_second_contact_name); secondContactPhoneNumber = (TextView) findViewById(R.id.edit_text_second_contact_phone); sharedpreferences = getSharedPreferences(mypreference, Context.MODE_PRIVATE); name.setText(sharedpreferences.getString(Name, "")); address.setText(sharedpreferences.getString(Address, "")); firstContactName.setText(sharedpreferences.getString(FirstContactName, "")); firstContactPhoneNumber.setText(sharedpreferences.getString(FirstContactPhoneNumber, "")); secondContactName.setText(sharedpreferences.getString(SecondContactName, "")); secondContactPhoneNumber.setText(sharedpreferences.getString(SecondContactPhoneNumber, "")); }

If you have controls within the template Repeater You can it. https://esausilva.com/2014/10/06/how-to-access-asp-net-controls-inside-an-outer-and-an-inner-asp-repeaters-controls-inside-two-asp-repeaters/ foreach (RepeaterItem item in rptPerfSts.Items) { var radioButtonList1 = ((RadioButtonList)item.FindControl("RadioButtonList1")); //aqui tomas el valor y lo insertas en la tabla } Now the big problem is that Repeater does not have the concept of DataKeyNames or DataKeys of GridView com to keep the key for each item it generates, for that you must use another technique as mentioned here https://forums.asp.net/t/1596267.aspx?get%20the%20Id%20with%20repeater Basically in the template defines <asp:Hidden ...> like being<asp:HiddenField ID="QuestionID" runat="server" value='<%# Eval("ID") %>' /> in this way you will rot in foreach Use the FindControl() and get the Id of the question to which to assign the answer

I don't know if you need to, but you can try to do this:On the server ' s side, provide the necessary data in the JSON format, with relevant headings (laAUGHS):$result = mysqli_query($con,"SELECT k_ls, v_ls FROM users"); $data = []; while($row = mysqli_fetch_assoc($result)) { //сохранит имена полей $data[] = $row; // добавить к результату } header("Content-type:application/json"); //отправить заголовок о типе контента echo json_encode($data); // и сами данные On the client's side, if you get the data, you can record them in line and in line. localStorage$.get( "http://blabla.com/vhod.php", { ... } ) .done(function( data ) { // получили JSON данные localStorage.setItem('myKey', JSON.stringify(data)); }); Then, when necessary, download data from localStoragevar strData = localStorage.getItem('myKey'); var data = JSON.parse(strData); and work them out.$.each(data, function(idx, v) { console.log( idx +': ' + v.k_ls + '/' + v.v_ls); });

I definitely would say that it is not common. At least I have yet to find it in Googles Material Design reference. Gmail utilises it to some extent, though, with letting you delete things while swiping. All in all, I'd say it is more of an iOS thing though, especially with the implementation of more that one option being revealed. Edit: Now that I have thought more about it I remember seeing from time to time, though (was it with the twitter app?). All in all I still think it is not the most common thing on Android. Also the animation is different in that the icons are static and are revealed upon swiping whereas in iOS they get pushed in from the side.

I don't think you'll find an article about that kind of thing.Do it like this:In the OBD, keep the lasers and infu what points are in the menu for them.In SharedPreferences, for example, to keep what kind of laser is now active.When you change the laser, you must have a method that displays the necessary lists/mensions for a particular laser, according to the infine from the laser facility.Nor will it be necessary to allow the application to be started by individual panels (activities) for different phases.

It's easier to convert into a mass by adding a true second argument in json_decode, and then about that.$data = json_decode($json, true); foreach($data['data'] as $datetime => $v) { foreach($v['USD'] as $val) { echo "$datetime $val<br>\n"; } }

You can go another way, add them to the layout and make them invisible (android:visibility="invisible), and then change them to the button when applied (View.setVisibility(View.VISIBLE));

We have to give permission.permissions) Manifeste + stiff 6.0 ++ I need to get a manual permit. This is an example:Explain where you use Oncreate or others. if (Build.VERSION.SDK_INT >= 23){ if (checkPermission(Manifest.permission.ACCESS_FINE_LOCATION,getApplicationContext(),this)) { //You fetch the Location here //code to use the } else { requestPermission(Manifest.permission.ACCESS_FINE_LOCATION,PERMISSION_REQUEST_CODE_LOCATION,getApplicationContext(),this); } } Also in class. public static void requestPermission(String strPermission,int perCode,Context _c,Activity _a){ if (ActivityCompat.shouldShowRequestPermissionRationale(_a,strPermission)){ Toast.makeText(getApplicationContext(),"GPS permission allows us to access location data. Please allow in App Settings for additional functionality.",Toast.LENGTH_LONG).show(); } else { ActivityCompat.requestPermissions(_a,new String[]{strPermission},perCode); } } public static boolean checkPermission(String strPermission,Context _c,Activity _a){ int result = ContextCompat.checkSelfPermission(_c, strPermission); if (result == PackageManager.PERMISSION_GRANTED){ return true; } else { return false; } } @Override public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) { switch (requestCode) { case PERMISSION_REQUEST_CODE_LOCATION: if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) { fetchLocationData(); } else { Toast.makeText(getApplicationContext(),"Permission Denied, You cannot access location data.",Toast.LENGTH_LONG).show(); } break; } } "All right, let's not forget the manifest <uses-permission android:name="android.permisssion.ACCESS_FINE_LOCATION"></uses-permission> <uses-permission android:name="android.permisssion.ACCESS_COARSE_LOCATION"></uses-permission> <uses-permission android:name="android.permisssion.INTERNET"></uses-permission> Change your code. if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) { // TODO: Consider calling // ActivityCompat#requestPermissions // here to request the missing permissions, and then overriding // public void onRequestPermissionsResult(int requestCode, String[] permissions, // int[] grantResults) // to handle the case where the user grants the permission.

The database requires:add a column with a date when the value is not relevant,Add a view in which only relevant records will be selected,Add a trigger to a insert that would remove the not-actual records.A cachetools module can be used for some piton data. https://cachetools.readthedocs.io/en/stable/#cachetools.TTLCache Cool.For large projects, such things are stored in https://redis.io/commands/expireat or memcached.

If I understand you correctly, you need to hand over some bell in. AsyncTask and pull the bulbeck method in the method onPostExecutepublic interface Callback{ onPostExecute(String result); } new GetUserInformation(getActivity(), "zz@zz", new CallBack(){ onPostExecute(String result){ tv.setText(result) } }); GetUserInformation:private Callback callback; protected void onPostExecute(String result) { super.onPostExecute(result); callback.onPostExecute(result); }

I'll suggest an easy method, although it may not be ideal.In the object window, there is the attribute history, which is a reference to the browsing history of your tab. You can save serializable information in this attribute. It can be a string, an array or non-circular JSON, I suggest you save the inner HTML from your table.When the user clicks the button to add a new line, invoke the replaceState method. The second argument is just a placeholder, pass an empty string not to cause error.let tabela = document.getElementById('minha_tabela'); /Altera o atributo value do HTML para ser o mesmo valor do JavaScript/ for (let el of tabela.querySelectorAll('input')) { el.setAttribute('value', el.value); } /Podesmos querer guardar mais de uma informação além da tabela, então vamos declarar um JSON para poder armazenar mais informações eventualmente/ let historico = history.state ? history.state : {}; historico.tabela = tabela.innerHTML; history.replaceState(historico, ''); Now you have the current state of your table in this state of navigation, when the user clicks back, you can access history. state to rebuild your table.In this same page that exists the table, invoke a function like this when you load the page:function carregaTabela() { /se existir algum conteúdo no state E existir uma tabela esse if é executado, senão é ignorado/ if (history.state && history.state.tabela) { document.getElementById('minha_tabela').innerHTML = history.state.tabela; } }
