    text
    copied!<p>Gosh, there must be a thousand different tutorials on android appwidgets and even more questions here, but I just cannot figure out why mine isn't working. <em>sigh</em> Rhetorical question: why can't the code be the same here as just about every other object with the setOnClickListener (new new Button.OnClickListener() { // do stuff }... Anyway, my widget shows up on the screen and the labels are correct, but when I tap on the widget, nothing happens. I've put breakpoints in all the places where I think something would happen, but nothing is being executed.</p> <p>Question 1: What code is executed after a widget is tapped?</p> <p>My widget doesn't really update when it is tapped. Rather, it just executes some code in the rest of my program. It just makes some networking http and/or socket server commands. Also, my widget is configured with an activity before it is placed on the desktop.</p> <p>Here's the manifest:</p> <pre><code> &lt;receiver android:name="PhcaAppWidgetProvider" &gt; &lt;intent-filter&gt; &lt;action android:name="android.appwidget.action.APPWIDGET_UPDATE" /&gt; &lt;action android:name="com.skipmorrow.phca.PhcaAppWidgetProvider.WIDGET_CLICKED" /&gt; &lt;/intent-filter&gt; &lt;meta-data android:name="android.appwidget.provider" android:resource="@xml/phca_widget_info" /&gt; &lt;/receiver&gt; </code></pre> <p>Here's the widget configurator activity</p> <pre><code> private Activity act; private static ListView listView; private static ArrayAdapter&lt;String&gt; adapter; private ArrayList&lt;String&gt; actionList; private final String widgetPageName = "_widget"; int mAppWidgetId = AppWidgetManager.INVALID_APPWIDGET_ID; private static final String PREFS_NAME = "PHCA"; private static final String PREF_PREFIX_KEY = "prefix_"; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setTitle("Choose an action for this widget"); actionList = GetActionList(); if (!actionList.isEmpty()) { listView = getListView(); adapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.simple_list_item_1, android.R.id.text1, actionList); setListAdapter(adapter); } else { // no objects on the widget page } // Find the widget id from the intent. Intent intent = getIntent(); Bundle extras = intent.getExtras(); if (extras != null) { mAppWidgetId = extras.getInt( AppWidgetManager.EXTRA_APPWIDGET_ID, AppWidgetManager.INVALID_APPWIDGET_ID); } // If they gave us an intent without the widget id, just bail. if (mAppWidgetId == AppWidgetManager.INVALID_APPWIDGET_ID) { finish(); } } private ArrayList&lt;String&gt; GetActionList() { ArrayList&lt;String&gt; l = new ArrayList&lt;String&gt;(); Page p = CommonActivity.GetPageNamed(getApplicationContext(), widgetPageName); if (p!=null) { if (p.pageObjects.size()==0) DisplayEmptyPageHelpDialog(); for (int i = 0; i &lt; p.pageObjects.size(); i++) { l.add(p.pageObjects.get(i).GetParsedMajorLabel(getApplicationContext()).toString()); } } else { CreateWidgetPage(); DisplayEmptyPageHelpDialog(); } return l; } private void CreateWidgetPage() { Page widgetPage = new Page(getApplicationContext()); widgetPage.setPageName(widgetPageName); widgetPage.SetPageType("list"); widgetPage.setNote("Widget Page"); widgetPage.setPageTitle("Widget Page"); widgetPage.setImageFilename(""); widgetPage.setTransparentImageOverlayFilename(""); widgetPage.InsertInstanceIntoDatabase(getApplicationContext()); } private void DisplayEmptyPageHelpDialog() { Dialog helpDialog = new Dialog(this); helpDialog.setContentView(R.layout.phca_help_dialog); helpDialog.setTitle("PHCA Widget"); TextView helpText = (TextView) helpDialog.findViewById(R.id.tvHelpText); helpText.setText("Your _widget page is empty. Please add an action to the _widget page so it can be used in a widget."); TextView subTitle = (TextView) helpDialog.findViewById(R.id.tvSubject); subTitle.setText("PHCA Widget configurator"); helpDialog.show(); } @Override protected void onListItemClick(ListView l, View v, int position, long id) { super.onListItemClick(l, v, position, id); SharedPreferences.Editor prefs = getSharedPreferences(PREFS_NAME, 0).edit(); prefs.putInt(PREF_PREFIX_KEY + mAppWidgetId, position); prefs.commit(); // Push widget update to surface with newly set prefix String majorLabel = CommonActivity.GetPageObjectAtIndex(getApplicationContext(), widgetPageName, position).GetParsedMajorLabel(getApplicationContext()).toString(); String minorLabel = CommonActivity.GetPageObjectAtIndex(getApplicationContext(), widgetPageName, position).GetParsedMinorLabel(getApplicationContext()).toString(); AppWidgetManager appWidgetManager = AppWidgetManager.getInstance(getApplicationContext()); PhcaAppWidgetProvider.updateAppWidget(getApplicationContext(), appWidgetManager, mAppWidgetId, majorLabel, minorLabel); Intent resultValue = new Intent(); resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, mAppWidgetId); setResult(RESULT_OK, resultValue); finish(); } </code></pre> <p>And here's my appwidget provider</p> <pre><code> public class PhcaAppWidgetProvider extends AppWidgetProvider { private static final String ACTION_CLICK = "WIDGET_CLICKED"; private final String widgetPageName = "_widget"; private static final String PREFS_NAME = "PHCA"; private static final String PREF_PREFIX_KEY = "prefix_"; @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int[] appWidgetIds) { // Get all ids ComponentName thisWidget = new ComponentName(context, PhcaAppWidgetProvider.class); //int[] allWidgetIds = appWidgetManager.getAppWidgetIds(thisWidget); final int N = appWidgetIds.length; for (int i=0; i&lt;N; i++) { int appWidgetId = appWidgetIds[i]; SharedPreferences myPrefs = context.getSharedPreferences(PREFS_NAME, context.MODE_WORLD_WRITEABLE); Integer objNum = myPrefs.getInt(PREF_PREFIX_KEY + appWidgetId, -1); if (objNum &gt; -1) { PageAction pa = (PageAction) CommonActivity.GetPageObjectAtIndex(context, widgetPageName, objNum); String majorLabel = pa.GetUnparsedMajorLabel(context).toString(); String minorLabel = pa.GetUnparsedMinorLabel(context).toString(); updateAppWidget(context, appWidgetManager, appWidgetId, majorLabel, minorLabel); } } } @Override public void onEnabled(Context context) { Log.d("Widget", "onEnabled"); } @Override public void onReceive(Context context, Intent intent) { String intentAction = intent.getAction(); updateWidgetState(context, intentAction); if (intentAction.equals(ACTION_CLICK)) { Bundle extras = intent.getExtras(); Integer appWidgetId = extras.getInt("appwidgetid"); SharedPreferences myPrefs = context.getSharedPreferences(PREFS_NAME, context.MODE_WORLD_WRITEABLE); Integer objNum = myPrefs.getInt(PREF_PREFIX_KEY + appWidgetId, -1); if (objNum &gt; -1) { PageAction pa = (PageAction) CommonActivity.GetPageObjectAtIndex(context, widgetPageName, objNum); pa.ExecuteActionFromWidgetClick(context); } } else { super.onReceive(context, intent); } } public static void updateWidgetState(Context paramContext, String paramString) { RemoteViews localRemoteViews = buildUpdate(paramContext, paramString); ComponentName localComponentName = new ComponentName(paramContext, PhcaAppWidgetProvider.class); AppWidgetManager.getInstance(paramContext).updateAppWidget(localComponentName, localRemoteViews); } private static RemoteViews buildUpdate(Context ctx, String paramString) { RemoteViews views = new RemoteViews(ctx.getPackageName(), R.layout.phca_appwidget); views.setTextViewText(R.id.majorlabel, "majorLabel"); views.setTextViewText(R.id.minorlabel, "minorLabel"); Intent intent = new Intent(ctx, PhcaAppWidgetProvider.class); intent.setAction(ACTION_CLICK); intent.putExtra("appwidgetid", 0); PendingIntent pendingIntent = PendingIntent.getBroadcast(ctx, 0, intent , 0); views.setOnClickPendingIntent(R.layout.phca_appwidget, pendingIntent); if(paramString.equals(ACTION_CLICK)) { Toast.makeText(ctx, "ACTION_CLICK", Toast.LENGTH_LONG).show(); } return views; } } </code></pre> <p>When I add the widget and remove it, different intents are passed into the onReceive, so that is working, but nothing when a click happens.</p> <p>Question 2: Can someone please be so kind as to point out what I did wrong? I pretty followed the tutorials here: <a href="http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/appwidget/ExampleAppWidgetProvider.html" rel="nofollow">http://developer.android.com/resources/samples/ApiDemos/src/com/example/android/apis/appwidget/ExampleAppWidgetProvider.html</a></p> <p>Question 3: It would seem that I could put an android:onclick="WidgetClicked" in the layout xml for the widget, but I couldn't figure out where to put the WidgetClicked method. The WidgetProvider seemed logical, but that didn't work for me either. Is there a way to do this in the xml?</p> <p>DISCLAIMER: the code above is the current state after a day and a half of troubleshooting. It just one iteration of many different tries.</p>
