android - Android Textviewsがフリーズする

Question

最初の数回でテキストビューが動かなくなることがありますが、その理由を誰か教えてください..特定のスレッドのテキストのみを更新する必要があると聞いたので、このスレッドを開始しました。

Runnable updateTextRunnable=new Runnable(){  
      public void run() {  
          count++;

                Location predicationPoint = DOTGpsAppUtils.predictionAlgorithm(latitude, longitude, bearing, distance);
                Location currentLocation = new Location("current");
                currentLocation.setLatitude(latitude);
                currentLocation.setLongitude(longitude);

                distance = DOTGpsAppUtils.distanceBetweenTwoLocations(currentLocation, predicationPoint);
                bearing = DOTGpsAppUtils.headingBetweenTwoLocations(currentLocation, predicationPoint);

                double predictionLongitude = (longitude + predicationPoint.getLongitude())/2;
                double predictionLatitude = (latitude + predicationPoint.getLatitude())/2;

                TextView textView = (TextView) findViewById(R.id.oneHundredMillisecondLatitude);
                textView.setText(Double.valueOf(predictionLatitude).toString());

                textView = (TextView) findViewById(R.id.oneHundredMillisecondLongitude);
                textView.setText(Double.valueOf(predictionLongitude).toString());

                textView = (TextView) findViewById(R.id.heading);
                textView.setText(Double.valueOf(bearing).toString());

                textView = (TextView) findViewById(R.id.speed);
                textView.setText(Double.valueOf(distance).toString());

                if(count >= 100)
                {
                    count = 0;
                }

                longitude = predictionLongitude;
                latitude = predictionLatitude;


          handler.postDelayed(this, TIME_DELAY);  
         }  
     };
