java - Activity 每次启动时都会增加 RAM 使用

Question

好吧，所以我有点困惑/沮丧。

我有一个始终运行的服务和一个 Activity 。每次启动和关闭 Activity 时，应用程序内存或 ram 使用都会增加。

我在 Activity 中只有图像和搜索栏。

我需要做什么来阻止它，因为它会很快累积起来!

我也有很多 getter 和 setter。比如tv.getText().toString()；和 bg.setBackgroundResource(R.drawable.icon);

因此，在我的 onCreate 中，它启动布局的 ID 等...每次创建 Activity 时，使用的内存或 ram 都会显着增加。它是复制资源还是什么？它以恒定的速度上升。

@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);                    
        }

您是否在 onDestroy() 中释放所有分配？
