  • These applications use an OnScrollListener to detect when the last item is displayed. When this happens, they load more items and add them to the list adapter.

android action bar opensource

shared by Vincent Tsao on 20 Jan 11 - No Cached
  • This projects aims to provide a reusable action bar widget. The action bar replaces the default title and is therefor located at the top of the screen. The action bar highlights important actions. The action bar pattern is well documented over at Android Patterns. The action bar widget is an Library Project. This means that there's no need to copy-paste resources into your own project, simply add the action bar widget as a reference to your existing project.

android array tip

shared by Vincent Tsao on 24 Nov 10 - No Cached
  • I am just trying to display a list from an array that I have in my arrays.xml.
  • String[] testArray = getResources().getStringArray(R.array.testArray); /** Called when the activity is first created. */ @Override protected void onCreate(Bundle savedInstanceState)
  • You can't initialize your testArray field this way, because the application resources still aren't ready.
  • ...1 more annotation...
  • protected void onCreate(Bundle savedInstanceState) {    super.onCreate(savedInstanceState);    // Create an ArrayAdapter that will contain all list items    ArrayAdapter<String> adapter;    mTestArray =  = getResources().getStringArray(R.array.testArray);        /* Assign the name array to that adapter and     also choose a simple layout for the list items */     adapter = new ArrayAdapter<String>(    this,    android.R.layout.simple_list_item_1,    mTestArray);    // Assign the adapter to this ListActivity    setListAdapter(adapter);    }}

Try loadDataWithBaseUrl() instead of loadData(), supplying some bogus value for the base URL (e.g., fake://why/o/why/is/this/needed).

android action bar UI

shared by Vincent Tsao on 19 Jan 11 - No Cached
  • The concept of ActionBar has been introduced with the Twitter application for Android. More recently, we have seen this widget in the Google I/O 2010 schedule application. To sum up, an ActionBar can be considered as an advanced title bar that is capable of: containing several ActionBaritems (similar to buttons) being styled so that the general look’n'feel of the application is in accordance with the underlying brand/visual identity containing a title to show the user a summary of the screen content featuring several user interaction pattern.

Application does not show up in Android Market for Motorola XOOM tablet - Stack Overflow - 0 views

shared by Vincent Tsao on 28 Mar 11 - No Cached
  • I had the same issue. Along with including android:xlargeScreens="true" I found this to be the fix.
  • The Android Market treats as though requesting a permission like CALL_PHONE also requests: <uses-feature android:name="android.hardware.telephony" /> The XOOM does not have telephony — the first Android Market-compliant device with that limitation. While it can have a data plan, it has no voice or SMS capability, and so it is treated as not having android.hardware.telephony. But, if you request permissions like CALL_PHONE, the Android Market by default will assume you need android.hardware.telephony. As a result, you will be filtered out of the Market for the XOOM. The solution is simple: for any hardware features that might be implied by permissions but that you do not absolutely need, manually add the appropriate element to your manifest with android:required="false": <uses-feature android:name="android.hardware.telephony" android:required="false" />

  • Google 的开源政策使 Android 迅速成长，但是在这个过程中，Android 分裂和用户体验差的批评就一直没有停止过。对于各厂商的定制，Google 一直采取放任的态度，因为这对 Google 核心业务的影响不大
  • 但是最近发生的一些事情已经让 Google 不安了，一是 Amazon 发布了自己的 Android Appstore。Amazon是一个很强大的内容提供商，而且可能会推出平板产品。如果 Amazon 和其它硬件厂商合作，或推出自己的 Android 产品，使 Amazon Appstore 与 Android 更好的整合，将会威胁到 Android Market。

android intent tech

shared by Vincent Tsao on 13 Dec 10 - No Cached
  • This article describes a technique you can use to find out whether the system contains any application capable of responding to the intent you want to use. The example below shows a helper method that queries the system package manager to determine whether there's an app that can respond to a specified intent. Your application can pass an intent to the method and then, for example, show or hide user options that the user would normally use to trigger the intent.
  • /** * Indicates whether the specified action can be used as an intent. This * method queries the package manager for installed packages that can * respond to an intent with the specified action. If no suitable package is * found, this method returns false. * * @param context The application's environment. * @param action The Intent action to check for availability. * * @return True if an Intent with the specified action can be sent and *         responded to, false otherwise. */public static boolean isIntentAvailable(Context context, String action) {    final PackageManager packageManager = context.getPackageManager();    final Intent intent = new Intent(action);    List<ResolveInfo> list =            packageManager.queryIntentActivities(intent,                    PackageManager.MATCH_DEFAULT_ONLY);    return list.size() > 0;}
  • @Overridepublic boolean onPrepareOptionsMenu(Menu menu) {    final boolean scanAvailable = isIntentAvailable(this,        "com.google.zxing.client.android.SCAN");    MenuItem item;    item = menu.findItem(R.id.menu_item_add);    item.setEnabled(scanAvailable);    return super.onPrepareOptionsMenu(menu);}

java - remove notification bar shadow in android app - Stack Overflow - 0 views

android title bar shadow UI

shared by Vincent Tsao on 21 Jan 11 - No Cached
  • <!-- Variation on the Light theme that turns off the title --><style name="Theme.IOSched" parent="android:style/Theme.Light">    <item name="android:windowNoTitle">true</item>    <item name="android:windowContentOverlay">@null</item></style>
  • The android:windowContentOverlay is your shadow, and setting it to @null in your theme will eliminate it. You can see this in action in the Google I|O 2010 conference app, which uses many of the same UI conventions as does the new Twitter app. However, right now, the Twitter app has not yet been open-sourced, which is why I point you to the I|O app. The code fragment above is from that app's styles.xml resource.
