How to pass the name of the item clicked to another class - android

How to pass the name of the item clicked on the on list item clicked through Intent?
is this correct?
public class View_PPT_List extends ListActivity {
private final String SAMPLE_DB_NAME = "project";
private final String PPT_TABLE_NAME1 = "notes";

SQLiteDatabase notesDB = null;

public void onListItemClick(ListView l, View view, final int position, long id) {

super.onListItemClick(l, view, position, id);
Intent ins = new Intent (View_PPT_List.this,PPTActivity.class);
ins.putExtra("com.example.tinio_bolasa_project.finame",
String.valueOf(position));
startActivity(ins);
}
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
try{
notesDB = this.openOrCreateDatabase(SAMPLE_DB_NAME, MODE_PRIVATE, null);
notesDB.execSQL("CREATE TABLE IF NOT EXISTS " +
PPT_TABLE_NAME1 +
" ( notes_ID INTEGER PRIMARY KEY AUTOINCREMENT, " + "subjid
INTEGER, " + "pptName VARCHAR, " + "pptPath VARCHAR);");
int x1 = getIntent().getIntExtra("pos",1);
Cursor c = notesDB.rawQuery("SELECT * FROM notes WHERE "+ x1 +"=subjid", null);
if (c != null ) {
if (c.moveToFirst()) {
do {
String pptid = c.getString(c.getColumnIndex("notes_ID"));
String ppt = c.getString(c.getColumnIndex("pptName"));
results.add(pptid + ppt);
}while (c.moveToNext());
}
}
this.setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1,results));
} catch (SQLiteException se ) {
Log.e(getClass().getSimpleName(), "Could not create or Open the database");
} finally {

i get error (java.runtimeExceptin: cannot instantiate activity ComponentInfo: Java.lang.nullpointerexception)..
how to pass the String name of the item :( pls help :(


This line
String nam = getIntent().getStringExtras("string");
should be
String nam = getIntent().getStringExtra("string"); // without the 's'


String nam = getIntent().getStringExtra("string"); //not getStringExtras
Because you have specified the tag (string) to get one String


You should pick up with:
String nam = getIntent().getStringExtra("string"); //without 's'

How to select an Object in my Listview

I have a RemoteCar Control app where on the MainActivity page there is a button "location" which you can click on to get redirected into another activity (locationActivity). In this activity im displaying a JSON File in a Listview and now I want to click on those objects to select them and display the location on the main page in something like a simple TextView nothing special. How can I do that?
This is my location page:
public class location extends AppCompatActivity {
private String TAG = location.class.getSimpleName();
private ListView lv;
ArrayList<HashMap<String, String>> locationList;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_location);
locationList = new ArrayList<>();
lv = (ListView) findViewById(R.id.list);
new GetContacts().execute();
}
private class GetContacts extends AsyncTask<Void, Void, Void> {
#Override
protected void onPreExecute() {
super.onPreExecute();
Toast.makeText(location.this, "Json Data is downloading", Toast.LENGTH_LONG).show();
}
#Override
protected Void doInBackground(Void... arg0) {
HttpHandler sh = new HttpHandler();
// Making a request to url and getting response
String url = "url";
String jsonStr = sh.makeServiceCall(url);
Log.e(TAG, "Response from url: " + jsonStr);
if (jsonStr != null) {
try {
//JSONObject jsonObj = new JSONObject(jsonStr);
// Getting JSON Array node
//JSONArray locations = jsonObj.getJSONArray("");
JSONArray locations_ = new JSONArray(jsonStr);
// looping through All Contacts
for (int i = 0; i < locations_.length(); i++) {
JSONObject c = locations_.getJSONObject(i);
String type = c.getString("type");
String name = c.getString("name");
String address = c.getString("address");
String lat = c.getString("lat");
String lon = c.getString("lon");
String icon;
if(c.has("icon")){
//your json is having "icon" Key, get the value
icon = c.getString("icon");
}
else{
//your json is NOT having "icon" Key, assign a dummy value
icon = "/default/icon_url()";
}
// tmp hash map for single contact
HashMap<String, String> location = new HashMap<>();
// adding each child node to HashMap key => value
location.put("type", type);
location.put("name", name);
location.put("address", address );
location.put("lat", lat);
location.put("lon", lon);
location.put("icon", icon);
// adding contact to contact list
locationList.add(location);
}
} catch (final JSONException e) {

Sorry for the wall of code I'm always unsure how much information to provide.

define your list of string as private out of onCreate

How to wait for an activity to finish in asynctask

replace SiteAdapter adapter;
with
ArrayAdapter<FTPSite> adapter
then in your adapter class you need to create a constructor like this
public SiteAdapter(Context context, int resource, int textViewResourceId, List<T> objects) {
super(context,resource,textViewResourceId,objects);
}
see documentation
EDIT:
when you declare you need to do
adapter = new SiteAdapter(this,r.layout.your_layout,new int[] {r.id.title},model);

My question is : when I input words in the EditText, nothing happened. But when I press backspace did the AutoCompleteTextView show the suggestion list ... the problem is in the editAuto.setAdapter(adapter);
What is wrong?

make the following changes in your code
1) Instead of
private AutoCompleteTextView editAuto = null; JUST WRITE private AutoCompleteTextView editAuto;
2) Add this line to onCrate()
ArrayAdapter<String> adapter = new ArrayAdapter<String>(this, android.R.layout.simple_dropdown_item_1line, <your array name here>);
and remove this line from onTextChangedTask()
ArrayList<String> userNameArrayList = new ArrayList<String>();
3) Add this line to onCrate()
editAuto.setAdapter(adapter);

I know this is way late but for those who face similar problems here is the solution to show the autoCompleteTextView's drop down whenever you want i.e on button click or onTextChanged. After you set the ArrayAdapter for the autoCompleteTextView just put the following line.
autoCompleteTextView.showDropDown();
