  • The Android system reuses Intents that match both action and scheme values—the "extras" values are not compared

      通过设置不同scheme来区别不同的intent
  • In practice, this means the Intent for each App Widget identifier would actually be the same Intent. Fortunately, the solution is straightforward: define a scheme for your App Widget and use it to define unique Intent instances
  • // make this pending intent unique widgetUpdate.setData( Uri.withAppendedPath(Uri.parse( ImagesWidgetProvider.URI_SCHEME + "://widget/id/"), String.valueOf(appWidgetId)));

How to implement a Button on an Android Widget - Stack Overflow - 0 views

android Widget button tech

shared by Vincent Tsao on 08 Jul 10 - Cached
  • I am just getting started with Android development and I have created a nice little widget that displays some info on my home screen. However, I now want to implement a Button on my widget that updates the info in my widget TextView.
  • Solved - I can confirm that an Activity is NOT needed if you want create a Button to update an Android AppWidget. I have been able to implement my AppWidgetProvider class such that it registers an android.appwidget.action.APPWIDGET_UPDATE intent-filter with the Broadcast receiver in the AndroidManifest.xml, which then fires the onUpdate event in the AppWidgetProvider class (which in turn then runs the UpdateService).
  • The UpdateService in my AppWidgetProvider class then uses onHandleIntent to run a private buildUpdate method - which registers the onClick event with a call to setOnClickPendingIntent as follows:
  • ...1 more annotation...
  • // set intent and register onclickIntent i = new Intent(this, MyWidget.class);PendingIntent pi = PendingIntent.getBroadcast(context,0, i,0);updateViews.setOnClickPendingIntent(R.id.update_button,pi);

Handling User Interaction with Android App Widgets - Developer.com - 0 views

shared by Vincent Tsao on 08 Jul 10 - Cached
  • An App Widget uses a special display control called RemoteViews. Unlike a regular View, a RemoteViews control is designed to display a collection of View controls in another process. Consequently, you can't simply add a button handler because that code would run in your application process, not in the process displaying the RemoteViews object (in this case, the Home Screen process).
  • In order to handle user interaction with an App Widget, the following tasks must be performed: Set a unique click handler for each App Widget control Have the click handler send a command to a registered receiver Process the command received and perform any action necessary Update the App Widget to reflect the changes

android adb sqlite

  • Then I went ahead and installed 2.2 and now when > I type sqlite3 in the shell it says sqlite3 not found....  Any ideas? Well, it's in the 2.2 emulator image, for what that's worth. -- Mark Murphy (a Commons Guy)

    Android 2.2 的真机中不再有sqlite调试工具了? WTF! ! !
  • Vincent Tsao on 08 Jul 10
     
    求助于China android dev开发小组，有了解决办法： step 1: 从其他真机或者模拟器的 /system/xbin目录下copy一份 sqlite3 step 2: 进入shell执行chmod a+x sqlite3 或者 chmod 777 sqlite3 大功告成

How to handle screen orientation change when progress dialog and background thread acti... - 0 views

android bug orientation View not attached to window manager

shared by Vincent Tsao on 14 Jul 10 - Cached
  • When you switch orientations, Android will create a new View. You're probably getting crashes because your background thread is trying to change the state on the old one. (It may also be having trouble because your background thread isn't on the UI thread) I'd suggest making that mHandler volatile and updating it when the orientation changes.
