Andreas Sommer commented on CB-1062:
------------------------------------
Here's some example code. I'm using ActionBarSherlock on my main activity to
provide a tab bar, and have a Cordova plugin that lets JavaScript code register
a callback for tab selection changes. This might be a specific case - you can
decide if it makes sense to replace the singleton pattern by a
getPluginInstance method.
{code:java}
import com.actionbarsherlock.app.ActionBar;
import my.TabBarBridgePlugin;
...
public final class MainActivity extends DroidGap implements
ActionBar.TabListener
{
@Override
public void onTabSelected(Tab tab,
android.support.v4.app.FragmentTransaction ft)
{
// Plugin not initialized yet at app startup
if(TabBarBridgePlugin.instance != null)
TabBarBridgePlugin.instance.triggerTabSelectedEvent((String)tab.getTag());
}
-----
public class TabBarBridgePlugin extends Plugin
{
public String callback;
public static TabBarBridgePlugin instance;
public TabBarBridgePlugin(){instance=this;}
public PluginResult execute(String action, JSONArray args, String
callbackId)
{
if(action.equals("setTabSelectedListener"))
{
this.callback = callbackId;
if(args.length() != 0)
throw new AssertionError("setTabSelectedListener takes no
arguments");
PluginResult res = new PluginResult(PluginResult.Status.NO_RESULT);
res.setKeepCallback(true);
return res;
}
else
{
return new PluginResult(PluginResult.Status.INVALID_ACTION);
}
}
public void triggerTabSelectedEvent(String tabName)
{
PluginResult res = new PluginResult(PluginResult.Status.OK, tabName);
res.setKeepCallback(true);
this.success(res, callback);
}
}
{code}
