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);

android javascript Froyo iOS4 benchmarks

  • We compared these findings with that of our tests of Apple's mobile Safari browser on the iPhone 4. The results show that the Android device delivers significantly faster JavaScript execution than the iPhone, scoring over three times better on V8 and almost twice as fast on SunSpider

    总是有这类比较Froyo和其他OS渲染JS性能的评测，难道是Google在鼓励更多web app运行在android浏览器下？

  • To find your minimum width and height in density-independent pixels (dp), use this formula: (number of cells * 74) - 2

  • 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

  • Additionally, you can feel free to use the Search bar selection mechanism as a replacement for tabs since it’s really just a fast pivot on a data set. If you have more than 3 data sets, tabs become problematic since no more than 3 can be onscreen at once. For example, look at how we implemented the Profile switching mechanism below:
  • The good news for developers is you get this highly functional contacts feature for free if users choose to sync contact information into your app

  • The good news for developers is you get this highly functional contacts feature for free if users choose to sync contact information into your app. QuickContact for Android provides instant access to a contact's information and communication modes.
  • ...3 more annotations...
  • QuickActions can be used as a replacement for our traditional dialog invoked by long press.
  • The dashboard pattern serves as a home orientation activity for your users. It is meant to include the categories or features of your application. We recommend including an Action bar on this screen as well. The dashboard can be static or dynamic. For example, in the case of our dashboard for Twitter, we used the goodness of Live Wallpapers introduced in 2.1 to create an animated dashboard complete with real-time trend bubbles and the Twitter bird silhouette.
  • You keep a search history so users upon returning to the search activity can have quick one-button access to previous searches.

  • Most Android Smartphones released this year will receive the Android 2.2 Froyo. If you have a 2009 HTC Magic, then you might receive the Android 2.2 Froyo as well. France’s 2nd largest largest mobile carrier SFR officially announced the Magic will be receiving the Froyo update.
  • T-Mobile USA said the myTouch 3G, basically the same thing as a HTC Magic would be updated with Froyo a bit later this year. So it looks like the old Magic will be receiving the new Google OS in the next few months.
