I want to design simple app widget which has two textview and two button for previous/next. I am getting difficult to handle button click in app widget. Actually my desire is,if user click on previous button i want to show previous value and if user click on Next button i want to show next value from database. How to know which button is clicked?
here i register button click listener like this
public static class UpdateWidgetService extends IntentService {
public UpdateWidgetService() {
super("UpdateWidgetService");
}
@Override
protected void onHandleIntent(Intent intent) {
AppWidgetManager appWidgetManager = AppWidgetManager
.getInstance(this);
int incomingAppWidgetId = intent.getIntExtra(EXTRA_APPWIDGET_ID,
INVALID_APPWIDGET_ID);
if (incomingAppWidgetId != INVALID_APPWIDGET_ID) {
updateOneAppWidget(appWidgetManager, incomingAppWidgetId);
}
}
private void updateOneAppWidget(AppWidgetManager appWidgetManager,
int appWidgetId) {
DatabaseManager dbManager = new DatabaseManager(this);
dbManager.open();
String contactNumber, date, status, message;
ArrayList<QueuedMessage> listOfQuedMessage = (ArrayList<QueuedMessage>) dbManager
.fetchContactNumber();
if (listOfQuedMessage.size() == 0)
Log.i("Db", "null");
else{
date = dbManager.fetchDate();
message = dbManager.fetchMessage();
status = dbManager.fetchStatus();
dbManager.closeDatabase();
RemoteViews views = new RemoteViews(this.getPackageName(),
R.layout.schdulesms_appwidget_layout);
views.setTextViewText(R.id.to_appwidget_saved_data,
listOfQuedMessage.get(count).contacNumber);
views.setTextViewText(R.id.date_appwidget_saved_data, date);
views.setTextViewText(R.id.status_appwidget_saved, status);
views.setTextViewText(R.id.message_appwidgset_saved_data, message);
**//here i want do**
if(button1){
btnNxtClick(views, appWidgetId,listOfQuedMessage.size());
}else{
btPrevClick(views, appWidgetId, listOfQuedMessage.size());
}
appWidgetManager.updateAppWidget(appWidgetId, views);
}
}
private void btnNxtClick(RemoteViews views, int appWidgetId,int sizeOfList) {
Intent btnNextIntent = new Intent(this, this.getClass());
btnNextIntent.putExtra(EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent btnNextPendingIntent = PendingIntent.getService(this,
0, btnNextIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.btnNext, btnNextPendingIntent);
}
private void btPrevClick(RemoteViews views, int appWidgetId,int sizeOfList) {
Intent btnNextIntent = new Intent(this, this.getClass());
btnNextIntent.putExtra(EXTRA_APPWIDGET_ID, appWidgetId);
PendingIntent btnNextPendingIntent = PendingIntent.getService(this,
0, btnNextIntent, PendingIntent.FLAG_UPDATE_CURRENT);
views.setOnClickPendingIntent(R.id.btnPrev, btnNextPendingIntent);
}
