每次启动活动都会增加RAM使用量

Question

Alright, so i am sort of confused/frustrated.

I have a service that is always running and an activity. Every time the activity is launched and closed the App memory or ram use raises.

All i have in the activity are images and a seekbar.

What would i need to do to stop this as it could very quickly build up!

I also have alot of getter and setters. Such as tv.getText().toString(); and bg.setBackgroundResource(R.drawable.icon);

---

So, in my onCreate it starts the ID's for the layouts and etc... every time the activity is created the memory or ram used will significantly raise. Is it duplicating the resources or something? It goes up at a constant rate.

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    requestWindowFeature(android.view.Window.FEATURE_NO_TITLE);
    setContentView(R.layout.lock_screen);
    tm = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);

    //DATE & TIME STATS
    DateLayout = (LinearLayout) findViewById(R.id.DateLayout);
    curhour = (TextView) findViewById(R.id.hourText);
    curmin = (TextView) findViewById(R.id.minText);
    curmonth = (TextView) findViewById(R.id.monthText);
    curday = (TextView) findViewById(R.id.dayText);
    curactualday = (TextView) findViewById(R.id.actualdayText);
    batt = (TextView) findViewById(R.id.batt);

    //updateClock();

    //PATHS & TARGETS
    SliderUnlockPath = (ImageView) findViewById(R.id.slider_unlock_path);
    SliderTextAnimation=(AnimationDrawable) SliderUnlockPath.getDrawable();

    //SLIDER
    seekbar = (SeekBar) findViewById(R.id.seekbar);
    seekbar.setOnSeekBarChangeListener( new OnSeekBarChangeListener() 
    {
    public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser){
        // TODO Auto-generated method stub
    }

    public void onStartTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub
        //SliderUnlockPath.setBackgroundResource(R.drawable.lockscreen_slider_path_light);
        SliderUnlockPath.setVisibility(ImageView.INVISIBLE);
    }
        @Override
        public void onStopTrackingTouch(SeekBar seekBar) {
        // TODO Auto-generated method stub
        //SliderUnlockPath.setBackgroundResource(R.drawable.lockscreen_slider_path);

        //IF RIGHTMOST (UNLOCK ZONE)
        int UnlockZone = seekbar.getProgress();
        if (UnlockZone > 86) UnlockZone = 100; {
            seekbar.setProgress(UnlockZone);
            SliderUnlockPath.setVisibility(ImageView.INVISIBLE);                    
        } 
        if (UnlockZone == 100) {
            mHandler.removeCallbacks(mUpdateTimeTask);
            finish();

        }

        //IF NOT RIGHTMOST
        int ResetZone = seekbar.getProgress();
        if (ResetZone < 86) ResetZone = 0; {
            seekbar.setProgress(ResetZone);
            SliderUnlockPath.setVisibility(ImageView.INVISIBLE);
            SliderUnlockPath.setVisibility(ImageView.VISIBLE);
            //SliderUnlockPath.setBackgroundResource(R.drawable.lockscreen_slider_path);
        }
    }

您是否要在onDestroy（）中释放所有分配？
