How to get Value of String OnClick of a ViewList in Android Studio

I am new to android studio.
I am making an app that lists names of teachers and the subjects thought and then every person has a different class. The teacher names and subjects though are stored in a TreeMap.
I am having difficulty as I want my app to feature sorts, so when outputted the positions of teachers are changed according to the sort. At the moment the items are sorted via hard code alphabetically and a switch case is used and the onclick integer position is obtained. However, I want to make the switch case make a decision according to the string of the itemClicked so whenever a sort is executed when the user clicks the correct class is displayed. Kindly see my code below:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView resultsListView = (ListView) findViewById(R.id.results_listview);
TreeMap<String, String> nameSubject = new TreeMap<>();
nameSubject.put("Richard Bonnici", "Maths"); //1
nameSubject.put("Natasha Mifsud", "English"); //2
nameSubject.put("Victor Valdes", "Computing"); //3
nameSubject.put("Jonathan Galea", "Computing"); //4
nameSubject.put("Jerome Micallef", "History"); //5
nameSubject.put("Tarah Galea", "Marketing"); //6
nameSubject.put("Micheal Gonzalez", "Maths"); //7
nameSubject.put("Jason Bartolo", "Chemistry"); //8
nameSubject.put("Jack Grech", "Chemistry"); //9
nameSubject.put("Anna Carbonaro", "Maltese"); //10
nameSubject.put("Kay Azzopardi", "Biology"); //11
nameSubject.put("George Micallef", "Physics"); //12
nameSubject.put("Gabriella Bonnici", "Maths"); //13
Map sortedMap = valueSort(nameSubject);
// Get a set of the entries on the sorted map
Set set = sortedMap.entrySet();
// Get an iterator
Iterator i = set.iterator();
List<HashMap<String, String>> listItems = new ArrayList<>();
SimpleAdapter adapter = new SimpleAdapter(this, listItems, R.layout.list_item,
new String[]{"First Line", "Second Line"},
new int[]{R.id.text1, R.id.text2});
Iterator it = nameSubject.entrySet().iterator();
while (it.hasNext()) {
HashMap<String, String> resultsMap = new HashMap<>();
Map.Entry pair = (Map.Entry) it.next();
resultsMap.put("First Line", pair.getKey().toString());
resultsMap.put("Second Line", pair.getValue().toString());
listItems.add(resultsMap);
}
resultsListView.setAdapter(adapter);
resultsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(android.widget.AdapterView<?> adapterView, View view, int i, long l) {
//
switch (i) {
case 0:
startActivity(new Intent(TeacherList.this, AnnaCarbonaro.class));

How to get the Download Manager ,download cancel callback? or else how to hide or remove this cancel from notification?

When a video is being downloaded there is a cancel option to cancel the download.but when i cancel the download i don't get any callback from DownloadManager to update the app UI.
This cancle option is only available in Android 7 .
Or else is there any option to hide or remove the cancel option from there.

After registering your broadcast receiver for DownloadManager.ACTION_DOWNLOAD_COMPLETE, you can check for DownloadManager status in the onReceive() method of the DownloadManager broadcast as follows -
private BroadcastReceiver downloadReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context arg0, Intent arg1) {
// TODO Auto-generated method stub
checkDownloadStatus();
}
};
private void checkDownloadStatus(){
// TODO Auto-generated method stub
DownloadManager.Query query = new DownloadManager.Query();
long id = preferenceManager.getLong(strPref_Download_ID, 0);
query.setFilterById(id);
Cursor cursor = downloadManager.query(query);
if(cursor.moveToFirst()){
int columnIndex = cursor.getColumnIndex(DownloadManager.COLUMN_STATUS);
int status = cursor.getInt(columnIndex);
int columnReason = cursor.getColumnIndex(DownloadManager.COLUMN_REASON);
int reason = cursor.getInt(columnReason);
switch(status){
case DownloadManager.STATUS_FAILED:
String failedReason = "";
switch(reason){
case DownloadManager.ERROR_CANNOT_RESUME:
failedReason = "ERROR_CANNOT_RESUME";
break;
case DownloadManager.ERROR_DEVICE_NOT_FOUND:
failedReason = "ERROR_DEVICE_NOT_FOUND";
break;
case DownloadManager.ERROR_FILE_ALREADY_EXISTS:
failedReason = "ERROR_FILE_ALREADY_EXISTS";
break;
case DownloadManager.ERROR_FILE_ERROR:
failedReason = "ERROR_FILE_ERROR";
break;
case DownloadManager.ERROR_HTTP_DATA_ERROR:
failedReason = "ERROR_HTTP_DATA_ERROR";
break;
case DownloadManager.ERROR_INSUFFICIENT_SPACE:
failedReason = "ERROR_INSUFFICIENT_SPACE";
break;
case DownloadManager.ERROR_TOO_MANY_REDIRECTS:
failedReason = "ERROR_TOO_MANY_REDIRECTS";
break;
case DownloadManager.ERROR_UNHANDLED_HTTP_CODE:
failedReason = "ERROR_UNHANDLED_HTTP_CODE";
break;
case DownloadManager.ERROR_UNKNOWN:
failedReason = "ERROR_UNKNOWN";
break;
}
Toast.makeText(AndroidDownloadManagerActivity.this,
"FAILED: " + failedReason,
Toast.LENGTH_LONG).show();
break;
case DownloadManager.STATUS_PAUSED:
String pausedReason = "";
switch(reason){
case DownloadManager.PAUSED_QUEUED_FOR_WIFI:
pausedReason = "PAUSED_QUEUED_FOR_WIFI";
break;
case DownloadManager.PAUSED_UNKNOWN:
pausedReason = "PAUSED_UNKNOWN";
break;
case DownloadManager.PAUSED_WAITING_FOR_NETWORK:
pausedReason = "PAUSED_WAITING_FOR_NETWORK";
break;
case DownloadManager.PAUSED_WAITING_TO_RETRY:
pausedReason = "PAUSED_WAITING_TO_RETRY";
break;
}
Toast.makeText(AndroidDownloadManagerActivity.this,

Toast.LENGTH_LONG).show();
break;
case DownloadManager.STATUS_PENDING:

downloadManager.remove(id);
break;

setting specific intent for the filtered items in list view in android

i have had this problem for the last two to three days....i am trying to set specific intents to each item clicked in the list view but the issue is that iam using the position parameter to get the position but is redirecting me according to the current filtered position yet i want the original position on the list view... i tried to use the getItem method within the switch case but but am confused which values i have to pass in the case: to match the position.any help is highly appreciated
below is the sample of the codes

If you have access the countries class, try adding the link & title to the country itself. It will allow the listview to just retreive the country and get the link & title from the object.
Like so:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Countries country= (Countries) adapter.getItemAtPosition(position);
Intent country_intent = new Intent(FrenchMenu.this, WebDirection.class);
country_intent ("url", country.getURL());
country_intent .putExtra("title", country.getTitle());
startActivity(country_intent);
}
}
});
Hope this helps
Edit:
So, in Countries : Create 2 variables for the link and title (String link, title). Edit the constructor and create getters and setters for those variables.
In the FrenchMenu class:
Add an array String[] links = { "The","bunch","Of","Links" }
And an array String[] titles = { "the","Same","here"}
Change your loop
for (int i= 0;i<countryNames.length;i++){
Countries countries = new Countries(countryNames[i], imgs[i]);
countrylist.add(countries);
}
To
for (int i= 0;i<countryNames.length;i++){
Countries countries = new Countries(countryNames[i], imgs[i],links[i],titles[i]);
countrylist.add(countries);
}
Then you can use the function in your onItemClickListener as I showed you above.

Detect when system starts a download

Is there a way to detect when the system starts a download and get information of it and force to download it to specific location? I googled it and results where not much helpful

Start this service class and then start your download it will print the result for status of download.
public class MyService extends Service {
private Timer timer;

timerTask = new TimerTask() {
#Override

// Log.d(MyService.class.toString(),

getDownloadData();
}
};
if (timer != null && timerTask != null) {
timer.schedule(timerTask, 0, SAMPLING_RATE);

EditText set selector position doesn't works

When I delete text inside EditText with clrFunc() I lost cursor (I see it flashing, but nothing happens if I type). I can't type back in. I have to click back onEditText and then I can type in.
/* WORKS PERFECT */
private void delFunc(){
String str = display.getText().toString();
if(str.length() > 0){
String strStart = str.substring(0, SELECTOR_POSITION-1);
String strEnd = str.substring(SELECTOR_POSITION);
display.setText(strStart + strEnd);
display.requestFocus();
display.setSelection(--SELECTOR_POSITION);
}
}
/* NOT FULLY WORKING */
private void clrFunc(){
display.setText(""); //text is set to ""
display.requestFocus(); //not working
display.setSelection(display.getText().length()); //not working
}
EDIT: Added more code, I'm building simple calculator.

P.S.: Sorry for my bad language.

If you want to directly type into the EditText you are missing the following in your method:
display.requestFocus();
EDIT
This is the method I am using to show the keyboard with focus, the different focus call could do the trick.
protected void showKeyboard(EditText edit) {
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(edit, 0);
edit.requestFocusFromTouch();
}
