I have set an event listener(onclick) for the listview but it is not firing.
Below is my code. I have put logcat entry as the test. But the log entry not printed and the new activity not started.
public class GetTenantList extends Activity implements OnItemClickListener {
private static String DB_NAME="meterapp.sqlite";
DatabaseHelperClass db= new DatabaseHelperClass( this,DB_NAME);
allTenants individualreadings;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.tenants);
allTenants individualreadings= new allTenants(this);
ListView listview =(ListView)findViewById(R.id.tenants);
listview.setBackgroundColor(color.holo_orange_dark);
listview.setAdapter(individualreadings);
listview.setOnItemClickListener(this) ;
}
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
#Override
protected void onPause() {
db.close();
super.onPause();
}
#Override
protected void onDestroy(){
db.close();
super.onDestroy();
}
#Override
protected void onStop() {
// TODO Auto-generated method stub
db.close();
super.onStop();
}
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long index) {
Intent intent = new Intent(this,EditTenants.class);
Tenants tenant=(Tenants)individualreadings.getItem(position);
String tenantid= Integer.toString(tenant.get_id());
Log.e("Testing Intent Filter", tenantid);
intent.putExtra("id", tenantid);
startActivity(intent);
}
}
Any reasons why it is not responding?

Here is the code for allTenants class.
package com.example.metermanager;

public class allTenants extends BaseAdapter {
#SuppressWarnings("unused")

private static String DB_NAME="meterapp.sqlite";
private List<Tenants> readings =new ArrayList<Tenants>();

public allTenants(Context context1) {

//close it

}
Tenants reading =readings.get(arg0);
TextView tenantTextView =(TextView)
view.findViewById(R.id.textView9);
tenantTextView.setText(reading.getFirstName());
TextView surnameTextView =(TextView)
view.findViewById(R.id.textView10);
surnameTextView .setText(reading.getSurName());
TextView othernamesTextView =(TextView)
view.findViewById(R.id.textView11);
othernamesTextView .setText(reading.getOtherNames());
TextView mobile1 =(TextView)
view.findViewById(R.id.textView12);
mobile1.setText(reading.getMobile1());
TextView mobile2TextView =(TextView)
view.findViewById(R.id.textView13);
mobile2TextView.setText(reading.getMobile2());
TextView dateaddedTextView =(TextView)
view.findViewById(R.id.textView14);
dateaddedTextView.setText(fm.format((reading.getDateAdded())));
CheckBox inactiveCheckbox =(CheckBox)
view.findViewById(R.id.chkinactive);
inactiveCheckbox.setChecked(reading.getInActive());
TextView inactivedateTextView =(TextView)
view.findViewById(R.id.textView16);
inactivedateTextView.setText(fm.format(reading.getDateInActive()));
TextView tenantid =(TextView)
view.findViewById(R.id.textView17);
String test= Integer.toString(reading.get_id());
tenantid.setText(test);
}catch(Exception e)
{
Log.e("Error loading data in All Tenants listbox",e.toString());
}
return view;
}
}
Check like this:
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
Intent intent = new Intent(GetTenantList.this,EditTenants.class);
Tenants tenant=(Tenants)individualreadings.getItem(position);
String tenantid= Integer.toString(tenant.get_id());
Log.e("Testing Intent Filter", tenantid);
intent.putExtra("id", tenantid);
startActivity(intent);
}
You are using just this as context.... change it to GetTenantList.this in your onItemClick. Also, you can change the intent parameters to:
#Override
public void onItemClick(AdapterView<?> arg0, View arg1, int position, long index) {
Intent intent = new Intent(GetTenantList.this,EditTenants.class);
Tenants tenant=(Tenants)individualreadings.getItem(position);
String tenantid= Integer.toString(tenant.get_id());
Log.e("Testing Intent Filter", tenantid);
Bundle params = new Bundle();
params.putString("id", tenantid);
intent.putExtras(params);
startActivity(intent);
}
I think you may have misread the setOnItemClickListener() documentation/examples. Try doing it like this:
listview.setOnItemClickListener(new OnItemClickListener()
{
#Override
public void onItemClick(AdapterView<?> arg0, View view, int position, long id)
{
//whatever code you wish to invoke, in this case
Intent intent = new Intent(getApplicationContext(),EditTenants.class);
Tenants tenant=(Tenants)individualreadings.getItem(position);
String tenantid= Integer.toString(tenant.get_id());
Log.e("Testing Intent Filter", tenantid);
intent.putExtra("id", tenantid);
startActivity(intent);
}
}
Don't forget to properly import the listener too!
Try using the ListView as member variable of the class.

}
}
when I am applying it ,I am having error:
DBHelper mydb;
DBHelper unresolved type.
How then to declare DBHelper? Where is the problem with my code
In the tutorial you can find this:
Datbase - Helper class
For managing all the operations related to the datbase , an helper class has been given and is called SQLiteOpenHelper. It automatically manages the >creation and updation of the datbase. Its syntax is given below
public class DBHelper extends SQLiteOpenHelper {
public DBHelper(){
super(context,DATABASE_NAME,null,1);
}
public void onCreate(SQLiteDatabase db) {}
public void onUpgrade(SQLiteDatabase database, int oldVersion, int newVersion) {}
}
in the Example section you can find the class DBHelper implemented.
The apk is a memo pad or something like that. First you can put the title and then the note and if you press the button "Save" the note is saved and it saves in database. And if you press the button "Notes", you can view a list with all notes saved in database and you can select all notes and in the top of screen, you can read how many notes are selected. Ok, it's fine but I need remove notes when the are selected and I press the button with bin icon in the top menu.
The code:
package com.example.u2tarea3;
import android.content.Context;
import android.database.sqlite.SQLiteDatabase;
import android.database.sqlite.SQLiteOpenHelper;
public class AnotacionesOpenHelperSingleton extends SQLiteOpenHelper {
private static AnotacionesOpenHelperSingleton instancia = null;

You'll need to remove the note from the database and the ListView, and then call ListViewAdapter.notifyDataSetChanged()
To delete from the datasource have a method in the class that deals with the datasource:
/**
* Delete a note given an id.
* #param id Key used to identify a note to delete.
*/
public void deleteNote(long id) {
System.out.println("Note deleted with id: " + id);
database.delete(ListOpenHelper.TABLE_MEMOS,
ListOpenHelper.ID + " = " + id,
null);
}
To refresh the ListView you could simply clear and re-add all the Views via the ListViewAdapter:
// Refresh adapter view with new data
ListAdapter.clear();
ListAdapter.addAll(dataSource.getAllNotes());
ListAdapter.notifyDataSetChanged();
Alternatively remove only a single element from the ListViewAdapter and call notifyDataSetChanged();.
I am working on an android app which is having functionality of tabs.
Everything is working fine but I am not able to call activtygroup from listadapter.
Here is my code for list adapter:

Please suggest me how to call activtygroup from listadapter.
Make it like this you can access everything by doing like this.
public class AddRemoveFriendScreen extends ActivityGroup implements OnClickListener, IServerResponse
{
#Override
protected void onCreate(Bundle savedInstanceState)
{
.......
}
class AllyListAdapter extends BaseAdapter
{
//Now you can call everything from ActivityGroup
}
}
Hope this will help you.
According to the android developper reference, you may use Fragments.
ActivityGroup is deprecated. Use the new Fragment and FragmentManager APIs instead; these are also available on older platforms through the Android compatibility package.
You can try this trick.
inviteBtn.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
if(ctx instanceof ActivityGroup){
Intent intent = new Intent(ctx.getParent(),AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.getParent().startActivity(intent);
}
else{
Intent intent = new Intent(ctx,AddRemoveFriendScreen.class);
//intent.putExtra("friendId", allyBean.getUserId());
ctx.startActivity(intent);
}
}
});
If it doesn't work just use internal class for your adapter in your AddRemoveFriendScreen class.
I am new to android and a little bit confused. i have a listView with image and text. Where, if I click on a Image it should start an activity, and if I click on text another activity.
Cod:
in
onCrete(){
listView = getListView();}
myBaseAdapterItemActivity = new MyBaseAdapterItemActivity(
ItemActivity.this, placeNameList);
setListAdapter(myBaseAdapterItemActivity);
myBaseAdapterItemActivity.notifyDataSetChanged();
listView.setTextFilterEnabled(true);
listView.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapter, View view,
int position, long id) {
// One Activity I can start without any problem
// In xml File I set for image clicable to true.
// What I want to do is like this
if(view.getId() == R.id.imageId)
{
Intent intent = new Intent(this, ImageActivity.class);
startActivity(intent);
}
else if(view.getID == R.id.textId)
{
Intent intent = new Intent(this, TextActivity.class);
startActivity(intent);
}
}}
And whenever I click on Image it does not not either in textView.
Any Idea
It has two solutions:
1) Instead on writing onItemClickListener for list you can do findviewbyid the textview and imageview in your custom adapter in getview method and then set onclick listeners on both of them.
2) You can use getChildAt method.... and check which child is your imageview and which is your textview. This is a work around so not much guaranteed.
Try with the below code.
Your adapter should be like below code. then your text and image click will create new activity.
Hi the code should be like below Hope this helps you.

In your MyBaseAdapterItemActivity, setOnClickListener((OnCLickListener)mContext) to the ImageVIew and TextView.
In your activity, extends OnClickListener.
write your startActivity(Intent) in the OnClick(View v) depending on v.getId()
In list item xml, for set android:onClick="onFirstLinkClick" and similarly for the image view also,
and the use following method in your activity
public void onFirstLinkClick(View V) {
}
I have created android apps to retrieving Listview using BaseAdapter from ArrayList but not displayed anything in Listview.

Thanking You
First, don't create any Activity object in your Adapter. Activity objects are created by Android itself, and they are used to display Views. It has nothing to do with adapters.
The layout you want to display your data in must contain a <ListView ... /> tag, with an android:id="#+id/whatEverId" attribute.
Then what you have to do is to retrieve the ListView object in your TimeTracker activity using its id :
ListView lv = (ListView) findViewById(R.id.whatEverId);
Then create your adapter and tell your ListView that the views you want it to display will be created by your custom adapter :
TimeTrackerAdapter adapter = new TimeTrackerAdapter(this, myListOfData);
lv.setAdapter(adapter);
myListOfData is your ArrayList containing the data. The rest is explicit and should do the job.
