Android内部类内存泄漏和上下文泄漏？

Question

我在我的闪屏使用处理器延迟重定向如下下一个活动..

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.entrance); 
     screenTimeOut(); 
    } 

    private void screenTimeOut() { 
      /* New Handler to start the next screen 
     * and close this Entrance after some seconds.*/ 
     new Handler().postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       initTracker(); 
       /* Create an Intent that will start the Next-Activity. */ 
       checkLoginStatus(); 
      } 
     }, SPLASH_DISPLAY_LENGTH); 
    } 

而在另一个活动正在传递上下文的一类并保持内部的上下文上按钮如下点击 ..

private Tools tools; 

tools = new Tools(DetailsScreen.this, true); 

工具

private Context _context; 
    private Fragment _fragment; 
    private Activity activity; 
    private String filePath = null; 
    private String camImagePath = null; 

    public Tools() { 
    } 

    public Tools(Context _context, boolean flag) { 
     this._context = _context; 
     this.activity = (Activity) _context; 
     initPath(); 
     if (flag) { 
      createImageFile(); 
     } 
    } 

这些中的任何一个都会成为泄漏的原因？

又有怎样使用处理程序如下..

private Handler mHandler = new Handler(); 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.entrance); 
     screenTimeOut(); 
    } 

private void screenTimeOut() { 
      /* New Handler to start the next screen 
     * and close this Entrance after some seconds.*/ 
     mHandler.postDelayed(new Runnable() { 
      @Override 
      public void run() { 
       initTracker(); 
       /* Create an Intent that will start the Next-Activity. */ 
       checkLoginStatus(); 
      } 
     }, SPLASH_DISPLAY_LENGTH); 
    } 


    @Override 
    protected void onDestroy() { 
     super.onDestroy(); 
     mHandler.removeCallbacksAndMessages(null); 
    } 

Answer 1

1. Handler和Runnable不应该匿名方式使用。
2. 您应该避免将整个活动作为参数传递给其他类。如果上下文是您想使用的所有内容activity.getContext()。
