Android :: Unable To Bind To Service
Sep 30, 2009i get an error message like 09-30 20:08:24.733: ERROR/AndroidRuntime(949): Caused by: android.content.ReceiverCallNotAllowedException: IntentReceiver components are not allowed to bind to services 09-30 20:08:24.733: ERROR/AndroidRuntime(949): at android.app.ReceiverRestrictedContext.bindService (ApplicationContext.java:136) so i guess you can't bind to a service in an AppWidgetProvider - although you can start the service just fine?

View 5 Replies View RelatedUnused Parameter In OnClick Method
Nov 18, 2013I did was use the search function and after 10 pages I could not see what I was looking for. In java, we use method parameters for a number of reasons but I've never used parameters in my methods unless I needed them..When defining a method in android for a button that I want to click, I had my method defined in XML under the Button element
[HIGH]androidnClick="showText"[/HIGH]
then, in my ProjectName.java file I defined the method
[HIGH]public void showText(View view){
}[/HIGH]
I was told that the View in the parameter is the view that was clicked.Button is a subclass of View as is TextView and since that is the case,is this the rule for just the onClick method? Also, why can I not pass the Button as a parameter? Button is the actual "View" being clicked, so why not Button?
Furthermore, are there other methods similar to this and if so, do they all follow the rule just like the View parameter, where let's say if I had a class called "A" and it had a subclass "B" and that class had a subclass "C", and if I wanted to use the onClick method, I can only pass the Highest Class as the parameter?
To simplify that, are there ever cases where I would pass anything else OTHER THAN "View" as the parameter to these methods?
Android :: Activity Bind To Service - Multiple Thread Design
May 28, 2010A new question about android and services. Currently I'm developing a App that should send images to a server. It should also be possible to send more images parallel. I made a service that creates for every image a new image. The activity can bind to that service and gather information about the progress. I want to show the current status for every image in a notification (and when the user clicks a notification, an activity with the progress for that image should be shown). But I get several problems with that approach. There are errors with binding, the notification pending event starts the activity completely new, so I lose information about currently sending images and so on. How I could design in a appropriate way.

Aug 9, 2010I have a ListView that uses different XML files to create Views and make items out of. One of these XML files contains a RatingBar. Everything displays and looks excellent. I'm trying to attach an onClick handler to the RatingBar to launch a new Activity. My RatingBar is of style ?android:attr/ratingBarStyleSmall; so it's just an indicator (I want the small RatingBar click to take the user to an Activity where they can do various ratings).
My problem is the onClick handler for the RatingBar never gets executed. What makes it more interesting is that I've used the same code to make a LinearLayout clickable and it works fine. My Adapter's getView looks as such:...............

View 5 Replies View RelatedAndroid : Updating Chat Data UI From Different Activity Method?
May 4, 2010I have a tab widget where one of the tabs is a chat-type feature. I want to update the chat data at an interval (variable depending on whether the chat tab is active or not).
The best approach seemed to be using an AsyncTask in my main TabActivity class, as that would avoid any issues of the chat activity being destroyed while in the background, while an AsyncTask was running. I wanted to ensure that the Activity isn't destroyed and recreated, thus causing my AsyncTask to be unable to modify the actual active Activity's data.
However, now that my AsyncTask is in the TabActivity activity, I don't have a direct way to call my Chat's ListAdapter notifyDataSetChanged() from my onPostExecute() method anymore. Is there a way to get a reference to a given Tab's current Activity from the TabHost/TabActivity?
Or, alternatively, can I assume my chat activity will never be destroyed as a child activity of the TabActivity activity (well, never destroyed while the TabActivity is active at least), and then just put the AsyncTask in the Chat Activity?

Android :: OnKeyDown Activity Method Triggered For Long Clicks
Dec 10, 2009I have an activity which overrides the onKeyDown method. The documentation states the following about onKeyDown: "Called when a key was pressed down and not handled by any of the views inside of the activity." The problem I have is that this method is being called even when the views inside the activity handle it. I have a button implementing a longPress listener. What I see on debugger when long clicking on the button with the center key is that first onKeyDown from the activity is called then the longPress listener from the button gets triggered. Even for Textviews, when long clicking on it with the center select, the activity onKeyDown gets triggered before the TextView processes the longclick (and shows the Input Method context menu).

enablecheck.setOnCheckedChangeListener(new OnCheckedChangeListener(){

Aug 6, 2010I have an activity A which uses SharedPreferences to share data with a service S, which is called from within A.Now when I call the stopService() method from A, the onDestroy() method in S is not called immediately.I thought that all the activities and services under a single apk run in just one process. Why then does the jump to onDestroy() not take place immediately instead I can see the output from onDestroy() after the further code in the activity A is executed.
View 5 Replies View RelatedAndroid :: Cannot Call Method Of View Object Inside Activity
Nov 7, 2010In my program I have a custom view object. Inside the view class is a method called foo. For some reason when I call foo from my activity, it doesn't fire. Here is the code:
XML of the custom view:
<com.company.application.MyView android:id="@+id/my_view" android:layout_width="wrap_content" android:layout_height="wrap_content" />
The activity code:
public class Main extends Activity { MyView mView;
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); setContentView(R.layout.main);
LayoutInflater li = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View v = li.inflate(R.layout.main, null); mView= (MyView) v.findViewById(R.id.my_view);
//A button to fire the method inside foo() Button switchLeft = (Button) findViewById(R.id.switch_left); switchLeft.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { callTest(); } } );
} public void callTest() { Log.w(this.getClass().getName(), "clicked left arrow");
mView.foo(); mView.postInvalidate();
} }
Finally here is foo:
public void foo() { mBackground = mContext.getResources().getDrawable(R.drawable.temp_canvas); Log.w(this.getClass().getName(), "background set");
}
The first log is always written when the button is pressed, but the second log is not because foo never fires. What is the deal here? Upon request, the full view
public class MyView extends View { Drawable mBackground; Context mContext;
public MyView (Context context) { super(context); mContext = context;
mBackground = mContext.getResources().getDrawable(R.drawable.leftarrow1);
} public MyView (Context context, AttributeSet attrs) {
super(context, attrs); mContext = context;
mBackground = mContext.getResources().getDrawable(R.drawable.leftarrow1);
} public void foo() { mBackground = mContext.getResources().getDrawable(R.drawable.temp_canvas);
Log.w(this.getClass().getName(), "background set"); }
@Override public void onDraw(Canvas canvas) { Paint paint = new Paint();
paint.setStyle(Paint.Style.FILL); // draw a solid blue circle
paint.setColor(Color.BLUE); canvas.drawCircle(20, 20, 15, paint);
// draw a test background mBackground.setBounds(0, 0, 300, 400);
mBackground.draw(canvas); }
}
