Start Activity By Listactivity

Start Activity By Listactivity - java

I'm trying to start a activity everytime an item is clicked on a ListView
i'm using database in my project and using global varaibles in my project
but not able to start GalleryFileActivity activity in project
If you need to know to each of the sections will also provide
Thank you for your continued efforts to advance the perfection
public class DataListView extends ListActivity {
final private ArrayList<String> results = new ArrayList<String>();
private String tableName = DBHelper.tableName;
private SQLiteDatabase newDB;
private String Path;
final private ArrayList<String> pikh = new ArrayList<String>();
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
final global folder = ((global)getApplicationContext());
openAndQueryDatabase();
displayResultList();
}
private void displayResultList() {
TextView tView = new TextView(this);
tView.setText("data is");
getListView().addHeaderView(tView);
setListAdapter(new ArrayAdapter<String>(this,
android.R.layout.simple_list_item_1, results));
ListView lstView = getListView();
lstView.setChoiceMode(ListView.CHOICE_MODE_MULTIPLE);
lstView.setTextFilterEnabled(true);
}
public void onListItemClick(
ListView parent, View v, int position,long id, global folder)
{
String pos=results.get(position-1);
super.onListItemClick(parent, v, position, id);
Toast.makeText(this,
"You have selected " + results.get(position-1) ,
Toast.LENGTH_SHORT).show();
folder.setsubfolder (pos);
**startActivity(new Intent(this,GalleryFileActivity.class));**
}
public void onClick(View view) {
ListView lstView = getListView();
}
private void openAndQueryDatabase() {
try {
DBHelper dbHelper = new DBHelper(this.getApplicationContext());
newDB = dbHelper.getWritableDatabase();
Cursor c = newDB.rawQuery("SELECT Path, Header FROM resource1 "
, null);
if (c != null ) {
if (c.moveToFirst()) {
do {
Path = c.getString(c.getColumnIndex("Path"));
String Header = c.getString(c.getColumnIndex("Header"));
results.add( Path + " " + Header);
}while (c.moveToNext()) ;
}
}
} catch (SQLiteException se ) {
Log.e(getClass().getSimpleName(), "Could not create or Open the database");
} finally {
if (newDB != null)
newDB.execSQL("DELETE FROM " + tableName);
newDB.close();
}
}
}

The code looks about right.
Sounds like you may not have GalleryFileActivity declared in your manifest.
Check your logcat output - there's probably an exception in there that mentions this.

pass data from one activity to another and save it

i have two activities, each one have a listview. The first one contain the data and i want the other one to be as a favorite list. Right now i can pass the data with intent but its not saving. it shows when i start the intent but when i exit the second activity and go back to it with a custom button nothing is saved in the listview.

note: i get the data in 1st listview from strings.xml
please help me thank u in advance

You can add a column say 'isFavourite' in your db table which has list vew data. When user mark listitem as favourite, save the change in db table . When user navigates to favourite list populate the list from. db table with favourite filter in select query.

I suggest using SharedPreferences. You stated that your value gets overwritten. That won't be the case if you create multiple keys.
Example:
Say you have an ArrayList of String you want to pass from ClassA to ClassB:
ClassA:
for (int i = 0; i < list.size(); i++) {
sharedPref.edit().putString("text" + i, "abcde").apply();
}
ClassB:
for (int i = 0; i < list.size(); i++) {
sharedPref.getString("text" + i, null);
}
If you have problems with the listsize, you can also pass the listsize to sharedpref and retrieve it again.

Listview isn't updating in Fragment

I know for sure that the updateFromDatabase() function works, I've used print statements to see that the entries put into mCoordinatesArray are there and not empty strings. However when I restart the app, the fragment never populates the list view with items in the database. I think it has something to do with the Fragment Lifecycle, but I have no idea.
Additionally, when I don't restart the app and run it for the first time the list view runs fine. When I rotate or restart the app, the list view no longer populates.
public class LocalFragment extends Fragment{
private ListView mLocalList;
private ArrayAdapter<String> adapter;
private ArrayList<String> mCoordinatesArray;
private BroadcastReceiver mBroadcastReceiver;
private LocationBaseHelper mDatabase;
private DateFormat dateFormat;
private String dateString;
#Override
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState){
View v = inflater.inflate(R.layout.fragment_local,container,false);
// SQLite Setup
mDatabase = new LocationBaseHelper(getActivity());
mLocalList = (ListView) v.findViewById(R.id.lv_local);
mCoordinatesArray = new ArrayList<>();
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, mCoordinatesArray);
if(!mDatabase.size().equals("0")){
updateFromDatabase();
}
mLocalList.setAdapter(adapter);
return v;
}
#Override
public void onResume() {
super.onResume();
if(mBroadcastReceiver == null){
mBroadcastReceiver = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
dateFormat = new SimpleDateFormat("MM/dd HH:mm:ss a");
dateString = dateFormat.format(new Date());
String[] data = intent.getStringExtra("coordinates").split(" ");
mDatabase.insertEntry(dateString,data[0],data[1]);
System.out.println(mDatabase.size());
mCoordinatesArray.add(dateString + " " + data[0] + " " + data[1]);
adapter.notifyDataSetChanged();
}
};
}
getActivity().registerReceiver(mBroadcastReceiver, new IntentFilter("location_update"));
}
#Override
public void onDestroy() {
super.onDestroy();
if(mBroadcastReceiver!=null){
getActivity().unregisterReceiver(mBroadcastReceiver);
}
}
// THIS METHOD CAN BE USED TO UPDATE THE ARRAY HOLDING COORDINATES FROM THE LOCAL DATABASE
private void updateFromDatabase(){
//mCoordinatesArray.clear();
mCoordinatesArray = mDatabase.getEntireDatabase();
adapter.notifyDataSetChanged();
}
}
Here's my Helper class, just in case, but I don't think the problem is here.
public class LocationBaseHelper extends SQLiteOpenHelper {
private static final int VERSION = 1;
private static final String DATABASE_NAME = "locationBase.db";
public LocationBaseHelper(Context context) {
super(context, DATABASE_NAME, null, VERSION);
}
#Override
public void onCreate(SQLiteDatabase db) {
db.execSQL("create table " + LocationTable.NAME + " (" +
LocationTable.Cols.DATE_TIME + " text, " +
LocationTable.Cols.LATITUDE + " text, " +
LocationTable.Cols.LONGITUDE + " text )"
);
}
#Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
}
public void insertEntry(String date_time, String latitude, String longitude){
SQLiteDatabase db = this.getWritableDatabase();
ContentValues content = new ContentValues();
content.put(LocationTable.Cols.DATE_TIME,date_time);
content.put(LocationTable.Cols.LATITUDE,latitude);
content.put(LocationTable.Cols.LONGITUDE,longitude);
db.insert(LocationTable.NAME,null,content);
}
public ArrayList<String> getEntireDatabase(){
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery("SELECT * FROM " + LocationTable.NAME,null);
cursor.moveToFirst();
ArrayList<String> values = new ArrayList<>();
do{
String value = (String) cursor.getString(cursor.getColumnIndex(LocationTable.Cols.DATE_TIME)) + " " +
(String) cursor.getString(cursor.getColumnIndex(LocationTable.Cols.LATITUDE)) + " " +
(String) cursor.getString(cursor.getColumnIndex(LocationTable.Cols.LONGITUDE));
values.add(0,value);
}while(cursor.moveToNext());
return values;
}
public String size(){
SQLiteDatabase db = this.getReadableDatabase();
Cursor cursor = db.rawQuery("SELECT COUNT(*) FROM " + LocationTable.NAME,null);
cursor.moveToFirst();
return cursor.getString(0);
}
}

By calling mCoordinatesArray = mDatabase.getEntireDatabase(); you are changing the reference of mCoordinatesArray, and adapter is still holding the old reference, so it does not see any changes.
Instead of creating new instance of mCoordinateArray, you should rather just update values it contains, something like:
mCoordinateArray.clear();
mCoordinateArray.addAll(mDatabase.getData());
adapter.notifyDataSetChange();
That way you are changing the data that is referenced by adapter, instead of creating completely new set of data which the adapter is not aware of.

Try to recreate your ArrayAdapter instead of using .notifyDataSetChanged():
// update Data
mCoordinatesArray = mDatabase.getEntireDatabase();
// create new adapter with new updated array
adapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, mCoordinatesArray);
// set adapter for the listview
mLocalList.setAdapter(adapter);

You can put this method in your fragment and call from activity that attach to fragment.
public void updateList(List<?> result) {
if (multimediaListRent.size()>0) {
multimediaGridView.setAdapter(gridMediaListAdapter);
multimediaListRent.clear();
}
gridMediaListAdapter.notifyDataSetChanged();
}

Search Database doesn't work

so I'm having a very weird problem. Basically I'm making an app that searches the database for the field 'country' and displays info based on the searched country. Now the weird part is that it only works for a few countries althrough the fields are all written the same and in the other activty with the same code it works flawlessly. What do you think the problem is?

Onclickitem and start new intent inside Cursor

I am a new guy to android development. I have created a SMS Inbox application.
I managed to get the SMS Inbox of the phone. Now I want to set a onclick method to open a specific message in a new activity with the phone number and the message.
Here is the code for my inbox activity. I do not understand, the place to put my onclicklistitem method.
public class MessageInboxActivity extends ActionBarActivity implements OnItemClickListener {
private static MessageInboxActivity inst;
ArrayList<String> smsMessagesList = new ArrayList<String>();
ListView smsListView;
ArrayAdapter arrayAdapter;
public static MessageInboxActivity instance() {
return inst;
}
#Override
public void onStart() {
super.onStart();
inst = this;
}
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_message_inbox);
smsListView = (ListView) findViewById(R.id.SMSList);
arrayAdapter = new ArrayAdapter<String>(this, R.layout.my_adapter_item, R.id.product_name, smsMessagesList);
smsListView.setAdapter(arrayAdapter);
smsListView.setOnItemClickListener(this);
refreshSmsInbox();
}
public void refreshSmsInbox() {
ContentResolver contentResolver = getContentResolver();
Cursor smsInboxCursor = contentResolver.query(Uri.parse("content://sms/inbox"), null, null, null, null);
int indexBody = smsInboxCursor.getColumnIndex("body");
int indexAddress = smsInboxCursor.getColumnIndex("address");
if (indexBody < 0 || !smsInboxCursor.moveToFirst()) return;
arrayAdapter.clear();
do {
String str = "SMS From: " + smsInboxCursor.getString(indexAddress) +
"\n" + smsInboxCursor.getString(indexBody) + "\n";
arrayAdapter.add(str);
} while (smsInboxCursor.moveToNext());
}
public void updateList(final String smsMessage) {
arrayAdapter.insert(smsMessage, 0);
arrayAdapter.notifyDataSetChanged();
}
public void onItemClick(AdapterView<?> parent, View view, int pos, long id) {
try {
String[] smsMessages = smsMessagesList.get(pos).split("\n");
String address = smsMessages[0];
String smsMessage = "";
for (int i = 1; i < smsMessages.length; ++i) {
smsMessage += smsMessages[i];
}
String smsMessageStr = address + "\n";
smsMessageStr += smsMessage;
Toast.makeText(this, smsMessageStr, Toast.LENGTH_SHORT).show();
} catch (Exception e) {
e.printStackTrace();
}
}
}
Can someone help me to start new activity with the phone number and the message.

I'd put this in a comment but I can't comment, can you clarify your problem? What activity are you trying to link to and what exactly do you want to achieve? it seems like you just need to add to your onItemClick()
String smsMessageStr = address + "\n";
smsMessageStr += smsMessage;
Intent in = new Intent(getApplicationContext,/*whatever activity you want to open*/);
in.putStringExtra(/*some static keystring*/,smsMessage);
startActivity(in);
but it's hard to say for sure without knowing more

Display data from SQLite database into ListView in Android

String[] args={id};
Cursor myCursor = db.rawQuery("SELECT client_sitename FROM " + CLIENT_SITES_TABLE + " WHERE client_id=?", args);
String results = "";
/*int count = myCursor.getCount();
String[] results = new String[count + 1];
int i = 0;*/
if (myCursor != null) {
if(myCursor.getCount() > 0)
{
for (myCursor.moveToFirst(); !myCursor.isAfterLast(); myCursor.moveToNext())
{
results = results + myCursor.getString(myCursor.getColumnIndex("client_sitename"));
}
}
}
return results;
}
One problem is that I'm returning a 'String' to the 'Cursor', but I'm not sure what is the best way around this, as I think I should be returning a Cursor.
Here's the ClientSites class where I want to display the data:
public class ClientSites extends Activity {
//public final static String ID_EXTRA="com.example.loginfromlocal._ID";
private DBUserAdapter dbHelper = null;
private Cursor ourCursor = null;
private Adapter adapter=null;
#SuppressWarnings("deprecation")
#SuppressLint("NewApi")
public void onCreate(Bundle savedInstanceState) {
try
{
super.onCreate(savedInstanceState);
setContentView(R.layout.client_sites);
Intent i = getIntent();
String uID = String.valueOf(i.getIntExtra("userID", 0));
ListView myListView = (ListView)findViewById(R.id.myListView);
dbHelper = new DBUserAdapter(this);
//dbHelper.createDatabase();
dbHelper.openDataBase();
ourCursor = dbHelper.getSitesByClientname(uID);
Log.e("ALERT", uID.toString());
startManagingCursor(ourCursor);
Log.e("ERROR", "After start manage cursor: ");
//#SuppressWarnings("deprecation")
//SimpleCursorAdapter adapter = new SimpleCursorAdapter(getBaseContext(), R.id.myListView, null, null, null);
CursorAdapter adapter = new SimpleCursorAdapter(this, R.id.myListView, null, null, null, 0);
adapter = new Adapter(ourCursor);
//Toast.makeText(ClientSites.this, "Booo!!!", Toast.LENGTH_LONG).show();
myListView.setAdapter(adapter);
myListView.setOnItemClickListener(onListClick);
}
catch (Exception e)
{
Log.e("ERROR", "XXERROR IN CODE: " + e.toString());
e.printStackTrace();
}
}
private AdapterView.OnItemClickListener onListClick=new AdapterView.OnItemClickListener() {
public void onItemClick(AdapterView<?> parent,
View view, int position,
long id)
{
Intent i=new Intent(ClientSites.this, InspectionPoints.class);
i.putExtra(ID_EXTRA, String.valueOf(id));
startActivity(i);
}
};
class Adapter extends CursorAdapter {
#SuppressWarnings("deprecation")
Adapter(Cursor c) {
super(ClientSites.this, c);
}
//#Override
public void bindView(View row, Context ctxt,
Cursor c) {
Holder holder=(Holder)row.getTag();
holder.populateFrom(c, dbHelper);
}
#Override
public View newView(Context ctxt, Cursor c,
ViewGroup parent) {
LayoutInflater inflater=getLayoutInflater();
View row = inflater.inflate(R.layout.row, parent, false);
Holder holder=new Holder(row);
row.setTag(holder);
return(row);
}
}
static class Holder {
private TextView name=null;
Holder(View row) {
name=(TextView)row.findViewById(R.id.ingredientText);
}
void populateFrom(Cursor c, DBUserAdapter r) {
name.setText(r.getName(c));
}
}
}
Here is the code I'm now using to try and display the data in the Listview. I have altered it somewhat from my original attempt, but still not sure what I'm doing wrong.
public void onCreate(Bundle savedInstanceState) {
try
{
super.onCreate(savedInstanceState);
//setContentView(R.layout.client_sites);
Intent i = getIntent();
String uID = String.valueOf(i.getIntExtra("userID", 0));
//int uID = i.getIntExtra("userID", 0);
//ListView myListView = (ListView)findViewById(R.id.myListView);
dbHelper = new DBUserAdapter(this);
dbHelper.createDatabase();
dbHelper.openDataBase();
String[] results = dbHelper.getSitesByClientname(uID);
//setListAdapter(new ArrayAdapter<String>(ClientSites.this, R.id.myListView, results));
//adapter = new ArrayAdapter<String>(ClientSites.this, R.id.myListView, results);
setListAdapter(new ArrayAdapter<String>(ClientSites.this, R.layout.client_sites, results));
//ListView myListView = (ListView)findViewById(R.id.myListView);
ListView listView = getListView();
listView.setTextFilterEnabled(true);
//ourCursor = dbHelper.getSitesByClientname(uID);
//Log.e("ALERT", uID.toString());
//startManagingCursor(ourCursor);
//Log.e("ERROR", "After start manage cursor: ");
//#SuppressWarnings("deprecation")
//SimpleCursorAdapter adapter = new SimpleCursorAdapter(getBaseContext(), R.id.myListView, null, null, null); // LOOK AT THIS IN THE MORNING!!!!!!!!!!!
//CursorAdapter adapter = new SimpleCursorAdapter(this, R.id.myListView, null, null, null, 0);
//adapter = new Adapter(ourCursor);
//Toast.makeText(ClientSites.this, "Booo!!!", Toast.LENGTH_LONG).show();
//myListView.setAdapter(adapter);
//myListView.setOnItemClickListener(onListClick);

I Created a Listview from a database. Here is the code I used for my app
Here is part of the database handler. It will return a List of Categories for my listview. It can return a list of Strings if that is what you need.
public List<Category> getAllCategorys() {
ArrayList<Category> categoryList = new ArrayList<Category>();
// Select All Query
String selectQuery = "SELECT * FROM " + TABLE_CATEGORY;
SQLiteDatabase db = this.getWritableDatabase();
Cursor cursor = db.rawQuery(selectQuery, null);
// looping through all rows and adding to list
try{
if (cursor.moveToFirst()) {
do {
Category category = new Category();
category.setID(Integer.parseInt(cursor.getString(0)));
category.setCategory(cursor.getString(1));
// Adding category to list
categoryList.add(category);
} while (cursor.moveToNext());
}
}finally{
cursor.close();
}
db.close();
// return category list
return categoryList;
Here is how I fill the ListView by calling the database.
int size = db.getCategoryCount();
List<Category> categoryList = db.getAllCategorys();
category_data = new String[size-1];
int i=0;
for(Category cn : categoryList)
{
category_data[i] = cn.getCategory(); // get the name of the category and add it to array
i++;
}
listAdapter = new ArrayAdapter<String>(this, R.layout.categoryrow, category_data);
listViw.setAdapter(listAdapter);
EDIT: Here is something that should work for you
public List<String> getSitesByClientname(String id) {
String[] args={id};
ArrayList<String> result = new ArrayList<String>();
SQLiteDatabase db = this.getWritableDatabase();
Cursor myCursor = db.rawQuery("SELECT client_sitename FROM " + CLIENT_SITES_TABLE + " WHERE client_id=?", args);
try{
if (myCursor.moveToFirst()){
do{
result.add(myCursor.getString(myCusor.getString(myCursor.getColumnIndex("client_sitename"));
}while(myCursor.moveToNext());
}
}finally{
myCursor.close();
}
db.close();
return result;
}
Use it like this
List<String> sites_data = dbHelper.getSitesByClientname(uID);
result_data = new String[sites_data.size()];
int i=0;
for(String s : sites_data)
{
result_data[i] = s; // get the name of the category and add it to array
i++;
}
listAdapter = new ArrayAdapter<String>(this, R.layout.client_sites, result_data);
listViw.setAdapter(listAdapter);

If you want to return the Cursor from dbHelper you can do something like this...
public Cursor getSitesByClientname(String id) {
String[] args={id};
return db.rawQuery("SELECT client_sitename FROM " + CLIENT_SITES_TABLE + " WHERE client_id=?", args);
}
I'd also take some time to read the listview tutorial

Start Activity By Listactivity - java

The code looks about right. Sounds like you may not have GalleryFileActivity declared in your manifest. Check your logcat output - there's probably an exception in there that mentions this.
