}
i have my code here that will show the data and display in listview my problem now is how can i click an item by its id? I tried using protected void onListItemClick(ListView l, View v, int position, long id) {} but its not working

Try this :
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
}
});

this work for me
getListView().setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String item = (String) getListAdapter().getItem(position);
if (position == 0) {
Toast.makeText(Mainadminvdictionary.this, item + " selected", Toast.LENGTH_LONG).show();
Intent intent = new Intent(Mainadminvdictionary.this, Mainuserstop10.class); startActivity(intent);
}
}
});

How to refresh or update a fragment after deleting from the database

I am new to android development, and i'm trying to build a simple hymn book,
I'm using bottom navigation, i use fragments on each tab to display numbers and titles of each hymn.
In my favourite fragments i have a list of favourite songs displayed using recycler view fetch from the database.
I use on long click listener to delete songs from the favorite table in the database, but any time i delete a
song my favorite fragment doesn't get refreshed or undated with current items. Please, how can I refresh or update
my favourite fragment anytime i delete a song. thank you!

Pass a listener to the adapter and invoke it at the time of item delete from database. Then update your list and as well as your adapter.Like this way:
First create a listener:
public interface UpdateListener {
void onValueChangedListener();
}
Initialize the listener in Adapter class that comes from fragment.
private UpdateListener updateListener;
public FavouriteAdapter(Context favContext, ArrayList<String> favNumbers, ArrayList<String> favTitles,UpdateListener updateListener ) {
this.favContext = favContext;
this.favNumbers = favNumbers;
this.favTitles = favTitles;
this.updateListener=updateListener;
}
holder.favParentLayout.setOnLongClickListener(new View.OnLongClickListener() {
#Override
public boolean onLongClick(final View view) {
new AlertDialog.Builder(view.getContext())
.setIcon(android.R.drawable.ic_dialog_alert)
.setTitle("Are you sure?")
.setMessage("Do you want to delete from favorites?")
.setPositiveButton("Yes", new DialogInterface.OnClickListener() {
#Override
public void onClick(DialogInterface dialogInterface, int which) {
try{
SQLiteDatabase favHymns = favContext.openOrCreateDatabase("Songs", MODE_PRIVATE, null);
favHymns.execSQL("DELETE FROM favorites where hymnNum = '"+hymn_no+"'");
Toast.makeText(favContext.getApplicationContext(), "hymn deleted ", Toast.LENGTH_LONG).show();
// when any item delete from database notify the fragment through this
// listener for updating your adapter
updateListener.onValueChangedListener();
}catch(Exception e){
e.printStackTrace();
}
}
})
.setNegativeButton("No", null)
.show();
return true;
}
});
// this method is needed for updating your adapter
public void update(ArrayList<String> favNumbers, ArrayList<String> favTitles){
this.favNumbers = favNumbers;
this.favTitles = favTitles;
}
Implement the listener in your fragment and reinitialize your list.
public class Favourites extends Fragment implements UpdateListener {
private void initRecyclerView(){
// pass listener
adapter = new FavouriteAdapter(this.getActivity(), favSongNumbers, favSongTitles,this);
}
private void updateFavSongs(){
favSongNumbers.clear;
favSongTitles.clear;
try{
favMessage.setText("");
SQLiteDatabase favHymns = this.getActivity().openOrCreateDatabase("Songs", MODE_PRIVATE, null);
Cursor c = favHymns.rawQuery("SELECT hymnNum, hymnTitle FROM favorites", null);
int hymnNumIndex = c.getColumnIndex("hymnNum");
int hymnTitleIndex = c.getColumnIndex("hymnTitle");
if(c.moveToFirst()) {
while (c != null) {
favSongNumbers.add(Integer.toString(c.getInt(hymnNumIndex)) + ". ");

Please init the loader in onActivityCreated(..) method in the fragment.. it will hopefully solve your issue
First override the method and the then initialize it there

Refresh a Loader when data is changed - android

I user LoaderManager and CursorLoader to load the data from my database using a ContentProvider.
Now, the initial load is fine. I have a ListView that display all the rows from the DB(only the names-String adapter).
Now, when I add/delete a row from the database, I want to refresh the ListView so it will display the recent changes.
Currently I just restart the loader with the method "restartLoader" whenever a change is commited but I want to ask if there is another way of doing this without restarting the loader.
Here is my activity class code:

}
}

Since you already have access to the loader, you may not expect that much of a change, but another way of implementing this is by having the cursor setting PhonyContentProvider.RINGTONES_URI as its notification uri and notifying the uri whenever the database data changes.
Relevant methods:
setNotificationUri
notifyChange

How to load an specific activity (multiple intent) on filter ListView- Item-Click?

There no error, but when i click a item of listview nothing happen. I have more than 10 items. and go to difference activities. Any idea? I'am beginner in eclipse also java.
Example:
1.Niat (ListView-OnItemClickListener) will go to NiatActivity.class
2.Lafaz (ListView-OnItemClickListener) will go to LafazActivity.class
Here my code. Thanks in advance.

startActivity(myIntent);
}
else if (openClass.equals("Lafaz")) {
Intent myIntent1 = new Intent(view.getContext(),
LafazActivity.class);
startActivity(myIntent1);
}
}
});
}
}

Use Reflection is better but also u can use of Hashmap
Use OF HashMap
HashMap<String, Class>hashMap=new HashMap<String, Class>();
hashMap.put("Niat",NiatActivity.class);
hashMap.put("Lafaz",LafazActivity.class);
hashMap.put("Solat",SolatActivity.class);
lv.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
String openClass = adapter.getItem(position);
Intent myIntent1 = new Intent(MainTwoActivity.this,
hashMap.get(openClass));
startActivity(myIntent1);
}

MaWhen starting a new activity you should use
Intent myIntent = new Intent(MainTwoActivity.this ,NiatActivity.class);
View getContext() doesnt carry the full context of your app. Read up here

how to make a clickable listview

Ok. I'm working on a project, I have already created the listview, but I want to click on it and go to another page e.g like when you click a button it goes to another page, exactly like that, this is my code so far:
import android.app.ListActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
import android.widget.Toast;
public class listV extends ListActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter( new ArrayAdapter<String>(this, R.layout.listview,Food));
ListView list = getListView();
list.setTextFilterEnabled(true);
list.setOnItemClickListener(new OnItemClickListener(){
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), ((TextView) arg1).getText(), Toast.LENGTH_SHORT).show();
}
});
}
static final String[] Food = new String[]{
"Physical Activity" , "Healthy Diet", "Childhood Obesity"
};
}
Any help would be appreciated.
I'm just a beginner so please try to explain in detail.

Looks like you're 95% of the way there. In your onItemClick method of the listener, you just have to start the new activity like you normally would. You can use the 3rd argument of the onItemClick to give you the position of the listview item that was click and use that to differentiate the activity you call OR pass it into a single activity:
#Override
public void onItemClick(AdapterView<?> arg0, View position, int arg2, long arg3) {

I am a fairly new programmer myself and I am attempting to create the same thing. A ListView where the user is able to click each individual item in the list and each item will start its own activity. Please check out my code based on the help you gave earlier.
package com.tylerbmc.test;
import android.app.ListActivity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemClickListener;
import android.widget.ArrayAdapter;
import android.widget.ListView;
public class Main extends ListActivity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
setListAdapter(new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,
getResources().getStringArray(R.array.abdominals)));
ListView list = getListView();
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
Intent i;
if (position == 1) {
i = new Intent(Main.this, Second.class);
startActivity(i);
}
else if (position == 2) {
i = new Intent(Main.this, Third.class);
startActivity(i);
}
}
});
}
}
