  @Override
        public void onCreate() {
            super.onCreate();
            mIv = new ImageView(this);
            mIv.setImageResource(R.drawable.ic_launcher);
            mContentResolver = getContentResolver();
            mProviderObserver = new ContentObserver(new Handler()){
        @Override
        public void onChange(boolean selfChange, Uri uri) {
            super.onChange(selfChange, uri);
            if(uri.compareTo(mUri) == 0 ){
                String weather =mContentResolver.getType(uri);
                setWeather( weather);
            }
        }
        };
        mContentResolver.registerContentObserver(mUri, true, mProviderObserver);
        rnsmc= new ReadNewSmsMissedCall(mContentResolver);
        rnsmc.setChangeTelephonyListener(new ChangeTelephonyListener() {
            public void onChange() {
                setImage();
            }
        });
        rnsmc.registerObserver();
            setImage();

你必须使用asynctask如下。

@Override
    protected void onPreExecute() {

//Start your custom animation here OR display progress dialog
}

doInBackground(....)
{

 // code for getting data from webservice
}

onPostExecute(...)
{
// stop your animation OR dialog
}

请参阅此示例。希望能帮助到你。
