I handle click events in a desktop widget this way:
1. Create a service that inherits IntentService to handle updating the
widget display
2. For each item that you want to be clickable, create an intent filter
entry in the manifest with a unique action name
3. When you update the widget display in your service, do the following
for each item that you want to handle a click event:
1. Create an intent with the appropriate action from your manifest
2. Use setOnClickPendingIntent() to call your service with the intent
created above
4. In the service's onHandleIntent() method, check the intent's
action and update your widget's display based on the action
*Here is some example code from my manifest (Step 2):*
<service
android:name=".services.RunningAppWgtUpdateService"
android:label="@string/app_widget_update_service"
android:exported="false" > <intent-filter>
<action android:name=".WgtUpdateService.ACTION_NEXT" />
<action android:name=".WgtUpdateService.ACTION_PREV" />
<action android:name=".WgtUpdateService.ACTION_CLICK_0" />
<action android:name=".WgtUpdateService.ACTION_CLICK_1" />
<action android:name=".WgtUpdateService.ACTION_CLICK_2" />
<action android:name=".WgtUpdateService.ACTION_CLICK_3"
/> <action
android:name=".WgtUpdateService.ACTION_REFRESH" />
<action android:name=".WgtUpdateService.ACTION_REFRESH_NO_UPDATE" />
<action android:name=".WgtUpdateService.ACTION_CLOSE_ALL"
/> <action
android:name=".WgtUpdateService.ACTION_MODE_OPEN" />
<action android:name=".WgtUpdateService.ACTION_MODE_CLOSE" />
<action android:name=".WgtUpdateService.ACTION_NO_OP" />
</intent-filter> </service>
*
Here is some example code from my service class to set the pending intent
(Step 3.1 & 3.2):*
//RunningAppWgtUpdateService is the name of my class that
handles updating the display of my widget
Intent newIntent = new Intent(context,
RunningAppWgtUpdateService.class);
newIntent.setAction("com.magouyaware.appswipe.WgtUpdateService.ACTION_MODE_OPEN");
ViewHolder.s_curView.setOnClickPendingIntent(R.id.wgt_mode_open_btn,
PendingIntent.getService(this, 0, newIntent, 0));
*
Here is some example code from my service class to update the widget based
on the intent's action (Step 4):*
@Override protected void onHandleIntent(Intent intent) {
if (intent == null) return; String action
= intent.getAction(); if (action != null &&
action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_NO_OP"))
return; m_needsUpdate = true; if
(action != null &&
action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_REFRESH_NO_UPDATE"))
m_needsUpdate = false; initializeUpdate();
if
(!action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_PREV")
&&
!action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_NEXT"))
{ setIndeterminate(); } if
(action != null &&
!action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_REFRESH"))
{ if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_NEXT"))
nextPage(); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_PREV"))
prevPage(); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_CLICK_0"))
processAppClick(m_app0Pkg); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_CLICK_1"))
processAppClick(m_app1Pkg); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_CLICK_2"))
processAppClick(m_app2Pkg); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_CLICK_3"))
processAppClick(m_app3Pkg); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_CLOSE_ALL"))
closeAllRunningApps(); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_MODE_OPEN"))
setOpenMode(true); else if
(action.equals("com.magouyaware.appswipe.WgtUpdateService.ACTION_MODE_CLOSE"))
setOpenMode(false); }
updateView(); finalizeUpdate(); }
