AsyncTask is a class. runOnUiThread() is a method. You pass a Runnable
to runOnUiThread(), and if you are on a background thread, the
Runnable is posted to the main application thread's work queue for
eventual processing. Whatever is inside the run() method of the
Runnable is guaranteed to run on the main application thread.
For example, here is a listener from an AIDL-defined remote service
that uses runOnUiThread() to ensure that the events are passed to the
activity on the main application thread:
private final IScriptResult.Stub callback=new IScriptResult.Stub() {
public void success(final String result) {
runOnUiThread(new Runnable() {
public void run() {
successImpl(result);
}
});
}
public void failure(final String error) {
runOnUiThread(new Runnable() {
public void run() {
failureImpl(error);
}
});
}
};
This is an instance of an anonymous inner class of the activity
itself, so successImpl() and failureImpl() are methods on the
activity.
