events not showing while using a library

I am using a library for calendar called "alamkanak weekview" and I tried to add an sqLite data base where I can add and delete the events and so i did make them the delete and adding to the data base works just fine but the showing of events is all once it shows no event after i add and once it show one but repeated the time that is the size of the elements in the table , i tried to fix this but couldn't because i lack experience in android
here's the class where i add my class that adds the events from the data base
public class BasicActivity extends BaseActivity {
public db_cal db;
public int newYear;
public int newMonth;
// public int idd = 0
// ;
private List<WeekViewEvent> getEventsForMonth(int year, int month) {
List<WeekViewEvent> tempList = new ArrayList<WeekViewEvent>();
Calendar tmpen=Calendar.getInstance();
db = new db_cal(getApplicationContext());
// Populate the week view with some events.
List<WeekViewEvent> events = new ArrayList<>();
List<events> evenement = db.getAllEvenement();
WeekViewEvent event= new WeekViewEvent();
events tmp;
for(events vent : evenement) {
Log.d("taille1", evenement.size() + "");
// tmp = vent.;
//event = new WeekViewEvent(tmp.getId(), tmp.getName(),tmp.getStart(), tmp.getEnd());
event.setId(vent.getId());
event.setName(vent.getName());
event.setStartTime(vent.getStart());
event.setEndTime(vent.getEnd());
//idd=idd+1;
Log.d("nom", vent.getName() + "");
event.setColor(getResources().getColor(randcol()));
events.add(event);
}
for (WeekViewEvent weekViewEvent : events) {
if ((weekViewEvent.getStartTime().get(Calendar.MONTH))+1 == month && weekViewEvent.getStartTime().get(Calendar.YEAR) ==
year) {
tempList.add(weekViewEvent);
}
}
return tempList;
}
public List<? extends WeekViewEvent> onMonthChange(int newYear, int newMonth) {
int month = newMonth;
return getEventsForMonth(newYear,month);// I tried to use newMonth-1 directly here but it dosen't work i don't know why but it doesn't matter
}

Android Spinner is not clickable or working while running app

I am relatively new to programming and recently started working with android. I have been breaking my brains all day over this problem I have with a spinner. I read several similar questions and found several solutions and examples but none of them work for me :(
package com.deitel.welcome;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;

import android.view.View;
import android.widget.AdapterView.OnItemSelectedListener;
public class Preferences extends Activity {
/** Called when the activity is first created. */
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_preferences);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.preferences, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_profile) {
Intent intent = new Intent(Preferences.this, Profile.class);
startActivity(intent);
}
else if (id == R.id.action_home) {
Intent intent = new Intent(Preferences.this, HomeScreen.class);
startActivity(intent);
}
else if (id == R.id.action_calendar) {

startActivity(intent);
}
else if (id == R.id.action_statistics) {

}
return super.onOptionsItemSelected(item);
}
public class MainActivity extends Activity {
private String[] states;
private Spinner spinner;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
states = getResources().getStringArray(R.array.countries_list);
spinner = (Spinner) findViewById(R.id.country_spinner);
ArrayAdapter<String> dataAdapter = new ArrayAdapter<String>(this,
android.R.layout.simple_spinner_item, states);
dataAdapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(dataAdapter);
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
}
}
}
And this is my customOnItemSelected java file:
package com.deitel.welcome;
import android.view.View;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.Toast;
public class CustomOnItemSelectedListener implements OnItemSelectedListener {
public void onItemSelected(AdapterView<?> parent, View view, int pos,
long id) {
Toast.makeText(parent.getContext(),
"On Item Select : \n" + parent.getItemAtPosition(pos).toString(),
Toast.LENGTH_LONG).show();
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
}
This is my resources file:
<?xml version="1.0" encoding="utf-8"?>
<resources>
<string name="spinner_prompt">Choose a country</string>
<string-array name="country_arrays">
<item>Malaysia</item>
<item>United States</item>

<item>France</item>
<item>Italy</item>
<item>Singapore</item>
<item>New Zealand</item>
<item>India</item>
</string-array>
</resources>
And this is of course my XML file:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:padding="10dip" >
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_marginTop="10dip"
android:text="#string/country_label"
android:textAppearance="?android:attr/textAppearanceLarge" />
<Spinner
android:id="#+id/country_spinner"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:prompt="#string/country_label" />
</LinearLayout>
Can anyone figure out what I did wrong?
Greetings! Rosa

This fragment of your code:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
Adds listener without any logic because you didn;t provide any inside overriden methods. What you should do is add your custom listener like that:
spinner.setOnItemSelectedListener(new CustomOnItemSelectedListener())

you have done nothing in your on item selected . try adding a toast message in your main activity's on item selected and why is there a need for creating a custom listener when you can use the default one?
try like this in your main activity:
spinner.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> parent, View view,
int position, long id) {
Toast.makeText(parent.getContext(),"spinner clicked",
Toast.LENGTH_LONG).show();
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
}
});
just try adding a toast in your default listener or else set the custom listener you have made.You are not setting it as your listener and hence nothing is happening.

Simple Spinner Example and Onclick listner
String[] tracks_time = { "3min", "5min", "10min" };
Spinner spinner_time = (Spinner)promptsView.findViewById(R.id.sp_time);
ArrayAdapter<String> sptime = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_single_choice, tracks_time);
spinner_time.setAdapter(sptime);
spinner_time.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener()
{
#Override
public void onItemSelected(AdapterView<?> parent, View arg1, int position ,long arg3)
{
int index = parent.getSelectedItemPosition();
// get stuff as per index
}
public void onNothingSelected(AdapterView<?> arg0)
{
}
});

Thanks everyone! You are right... I found out that I actually created another class within my activity and did nothing in the original activity. Thanks for your help!
I kind of copied everything into the first class and added some stuff. Here is the code that worked for me in the end:
public class Preferences extends Activity {
protected CharSequence[] _options = { "Monday", "Tuesday", "Wednesday",
"Thursday", "Friday", "Saturday", "Sunday" };
protected boolean[] _selections = new boolean[_options.length];
protected Button _optionsButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_preferences);
_optionsButton = (Button) findViewById(R.id.button1);
_optionsButton.setOnClickListener(new ButtonClickHandler());
}
public class ButtonClickHandler implements View.OnClickListener {
public void onClick(View view) {
showDialog(0);
}
}
#Override
protected Dialog onCreateDialog (int id) {
return new AlertDialog.Builder(this)
.setTitle("Preferred Exercise Days")
.setMultiChoiceItems(_options, _selections,
new DialogSelectionClickHandler())
.setPositiveButton("OK", new DialogButtonClickHandler())
.create();
}
}
public class DialogSelectionClickHandler implements
DialogInterface.OnMultiChoiceClickListener {
public void onClick(DialogInterface dialog, int clicked,
boolean selected) {
Log.i("ME", _options[clicked] + " selected: " + selected);
}
}
public class DialogButtonClickHandler implements
DialogInterface.OnClickListener {
public void onClick(DialogInterface dialog, int clicked) {
switch (clicked) {
case DialogInterface.BUTTON_POSITIVE:
String selected = "";
int i = 0;
for (boolean b : _selections) {
if (b) {
selected += _options[i] + " ;";
}
i++;
}
printSelectedDays();
Toast.makeText(Preferences.this, "Selected: " + selected,
Toast.LENGTH_SHORT).show();
break;
}
}
}
protected void printSelectedDays() {
for (int i = 0; i < _options.length; i++) {
Log.i("ME", _options[i] + " selected: " + _selections[i]);
}
}
The solution is kind of different but it is actually what I wanted to achieve in the first place so I hope someone can use this after all.

Android: Adding functionality that activty changes when game is complete

I wish to add the following functionality to my game:
-When the game is complete (no more cards are visible on screen) then move to a new activity
I am aware how to move to another activty using intents but I am not sure how to implement the functionality in this case.
I.e. what variable/info can I use to ensure the game is complete when I move before moving to the next activity?
For reference, The game is based off this open source game Images of the game are shown here to give an idea.
Current code:

}

seconedCard.button.setBackgroundDrawable(backImage);
firstCard.button.setBackgroundDrawable(backImage);
}
firstCard=null;
seconedCard=null;
}
}
}

The easiest way to do this would be to check win conditions with an if statement. This should be done in the method when a turn is actually taken which I assume happens in the turnCard() method.
if (winConditionMet) {
displayWinningScreen();
} else if (lossConditionMet) {
displayLosingScreen();
}
If conditions have been met, then call a method which handles wrapping up that screen, and then launching a new activity. For instance you could add a button to the screen with whatever text you wanted, that when pushed, would take the user to the next screen, be it your score screen, replay screen, main menu, or what have you.
Edit: Okay, since this is a game of memory, you could iterate through the cards at the end of every turn taken and check if any card still has its image set to backImage. If there are none left that are set to backImage, you can then end the game with your code inside of the if statement.
Or, instead of using an ArrayList, you could use some form of Map to keep track of if each card has been permanently turned up or not with the boolean value.

disable second spinner click till 1st spinner get its value : android

I have a program in android where spinner gets the data dynamically from rest services. what i want to achieve is when the first spinner loads its value, the selected value loads the value of 2nd and third spinner. i want to disable the click of 2nd and third spinner till the spinner gets populated are loaded in all the spinner.
I call the function of populating 2nd & 3rd spinner in the end of the program.
public void addItemsOnSpinner1()
{
Bundle extras = getIntent().getExtras();

Try this..
Change your first element from m_Project_list ArrayList as Select
And after user selecting spinner you can do other operation below codes inside onCreate
Code
s1.setSelection(0);
s1.setOnItemSelectedListener(new OnItemSelectedListener(){
#Override
public void onItemSelected(AdapterView<?> arg0, View arg1,
int pos, long arg3) {
// TODO Auto-generated method stub
if(pos == 0){
s2.setEnabled(false);
s3.setEnabled(false);
}
else{
// do something
addItemsOnSpinner2(SelectedProjectID);
s2.setEnabled(true);
addItemsOnSpinner3(SelectedProjectID);
s3.setEnabled(true);
}
}
}
#Override
public void onNothingSelected(AdapterView<?> arg0) {
// TODO Auto-generated method stub
}
});
EDIT
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Log.i("=========="," handler == > ");
Toast.makeText(getBaseContext(), "handler", Toast.LENGTH_LONG).show();
}
}, 5000);

The only solution I got is to use delay function to solve this kind of spinner as told to me by hariharan.
ADD these two statements in spinner 1 function
s1.setOnItemSelectedListener(new OnItemSelectedListener() {
#Override
public void onItemSelected(AdapterView<?> adapter, View v,
int position, long id)
{
// On selecting a spinner item
final String item1 = adapter.getItemAtPosition(position).toString();
final String SelectedProjectID = m_projectID_list.get(s1.getSelectedItemPosition());
s2.setEnabled(false);
s3.setEnabled(false);
addItemsOnSpinner2(SelectedProjectID);
addItemsOnSpinner3(SelectedProjectID);
delay1();
//
}
#Override
public void onNothingSelected(AdapterView<?> arg0)
{
// TODO Auto-generated method stub
}
});
then use the below function
public void delay1()
{
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run()
{
s2.setEnabled(true);
s3.setEnabled(true);
}
}, 3000);
}

how to pass value data between classes/activity in Android?

For example i have activity1, activity2, activity3 and lastly valueAllActivity?
how do I pass the data from activity1, activity2, activity3 to --> valueAllActivity?
to pass INT value in each activity to valueAllActivity.
I am very new in developing Android program, so if anyone could guide, it would be an honor :)
Thank you

thank you anyone who try to help me. much appreciated :) as you know, I on my early stage developing the program, so thank you very much everyone :)

You would do it via intents. Assume data1 and data 2 are Strings and data3 is an int.
In your first activity when you set the intent to call the next activity:
Intent myIntent = new Intent(Activity1.this, Activity2.class);
myIntent.putExtra("Data1", data1);
myIntent.putExtra("Data2", data2);
myIntent.putExtra("Data3", data3);
Activity1.this.startActivity(myIntent);
Then in Activity 2:
Private String data1;
Private String data2;
Private int data3;
Bundle extras = getIntent().getExtras();
if (extras != null) {
data1 = extras.getString("Data1");
data2 = extras.getString("Data2");
data3 = extras.getInt("Data3");
}
// other code
Intent myIntent = new Intent(Activity2.this, Activity3.class);
myIntent.putExtra("Data1", data1);
myIntent.putExtra("Data2", data2);
myIntent.putExtra("Data3", data3);
Activity2.this.startActivity(myIntent);
And so on, through as many activities as you want.
You can Use any identifier you want. Above I used Data1, Data2, Data3. They could have as well been called Make, Model and TopSpeed. As long as you use the same id to get the data as you use to put it, it'll be fine.
EDIT
Several things I see...
First, use the getExtra to get the data out of the bundle in your onCreate method for each activity. Put the intents to call the next activity wherever you need to.
Then, one of your issues is here in activity 2:
if (extras != null){
totalKalori1 = extras.getInt("totalBreakfast");
totalKalori2 = extras.getInt("totalLunch");
}
You haven't put totalLunch into the bundle yet, so you shouldn't be trying to get it yet. Delete that line.
Same thing in Activity 3:
if (extras != null){
totalKalori1 = extras.getInt("totalBreakfast");
totalKalori2 = extras.getInt("totalLunch");
totalKalori3 = extras.getInt("totalDinner");
}
You haven't put totalDinner into the bundle yet, so you shouldn't be trying to get it yet. Delete that line.
Then in Calculate All you set an unnecessary intent and restart the activity... which looks to me like it would result in an infintie loop:
Intent n= new Intent(this, CalculateAll.class);
n.putExtra("totalBreakfast", totalKalori1);
n.putExtra("totalLunch", totalKalori2);
n.putExtra("totalDinner", totalKalori3);
startActivity(n);
Delete this whole section from the 'CalculateAll` activity.
I think moving the getExtra parts and removing the bad data will fix your issue.

You have several options:
Use intents to pass data when you move between activities.
Use a global application state bean, which you create by extending the Application class, which you can then access in your activity by calling the getApplication() method.
Use the SharedPreferences api if the shared data is something that will be provided by the user.
Persist data to the SQLite database and retrieve it in each Activity, if you want the data to be available even when the application is shutdown and restarted.
Read the documentation for all available ways in which you can store and retrieve data in your application.

You have some possibilities.
One that I like more is using the application context...
Create a new class like:
public class DataApp extends Application{
private int myInt;
private MyCustomObject myObj;
public int getMyInt() { return myInt; }
public void setMyInt(int i) { this.myInt = i; }
public MyCustomObject getMyObj() { return myObj; }
public void setMyObj(MyCustomObject ob) { this.myObj = ob;}
}
Add this to you manifest:
<application
android:name=".DataApp"
...>
...
</application>
After, when you need to pass data you can do this in your activity:
DataApp dataInfo = (DataApp)getApplicationContext();
//set some data:
dataInfo.setMyObj(/*put the object*/);
In your other activity, you get you object like this:
DataApp dataInfo = (DataApp)getApplicationContext();
MyCustomObject obj = dataInfo.getMyObj();
With this option, you can pass every object type you want.

The recommended way to pass data from one activity to another is via intents.
Have a look at this tutorial.

I used a method in an activity to call another activity.
It starts a game with two variables (resume and number of players).
private void MethodToCallAnotherActivity(int resume, int players) {
Intent intent = new Intent(CurrentActivity.this, NextActivity.class);
intent.putExtra(NextActivity.RESUME, resume);
intent.putExtra(NextActivity.PLAYERS, players);
startActivity(intent);
}
in the 'onCreate' of the NextActivity, I used
int resume = getIntent().getIntExtra(Game.RESUME, 1);
to read the variable I wanted.
Good luck!

To pass using the intent just do like that:
private String fUserName;
private String fPassword;
private Boolean fUseProxy;
private String fProxyAddress;
private Integer fProxyPort;
/** Called when the activity is first created. */
#Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.dashboard_activity);
fProjectsButton = (Button) findViewById(R.id.dashProjectsButton);
fUserName = "something";
fPassword = "xxx";
fUseProxy = false;
fProxyAddress = "";
fProxyPort = 80;
fProjectsButton.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(CodeBaseClientDashBoardActivity.this, CodeBaseClientProjectsActivity.class);
i.putExtra(CodeBaseClientSettingsActivity.PREFERENCE_API_USERNAME, fUserName);
i.putExtra(CodeBaseClientSettingsActivity.PREFERENCE_PASSWORD, fPassword);
i.putExtra(CodeBaseClientSettingsActivity.PREFERENCE_USE_PROXY, fUseProxy);
i.putExtra(CodeBaseClientSettingsActivity.PREFERENCE_PROXY_ADDRESS, fProxyAddress);
i.putExtra(CodeBaseClientSettingsActivity.PREFERENCE_PROXY_PORT, fProxyPort);
startActivity(i);
}
});
}
