啓動器中的按鈕首頁不工作

Question

我開發了自己的Android啓動器，它工作得很好，問題是當我單擊HOME按鈕時它不會將我重定向到HOME頁面，我該如何解決此問題， 謝謝！

退房Home - 自定義啓動的樣本。以下是關鍵事件的調度程序：

@Override 
public boolean dispatchKeyEvent(KeyEvent event) { 
    if (event.getAction() == KeyEvent.ACTION_DOWN) { 
      ... 
      case KeyEvent.KEYCODE_HOME: 
       mHomeDown = true; 
       return true; 
     } 
    } else if (event.getAction() == KeyEvent.ACTION_UP) { 
     switch (event.getKeyCode()) { 
      ... 
      case KeyEvent.KEYCODE_HOME: 
       if (!event.isCanceled()) { 
        // Do HOME behavior. 
       } 
       mHomeDown = true; 
       return true; 
     } 
    } 

    return super.dispatchKeyEvent(event); 
} 

您可以在註釋說明的位置實現自己的行爲。在這個例子的情況下，調用隱藏應用程序網格將會是hideApplications()。
