在这个应用程序中，他们以某种方式有能力保护用户的主页按钮（按下后没有主页对话框）。我知道这是不可能的，但他们是怎么做到的？

清单，没有关于启动器的消息。

代码中还有一些有趣的行

  public static void disableHome(Context paramContext, PackageManager paramPackageManager)
  {
    paramPackageManager.setComponentEnabledSetting(new ComponentName(paramContext, "com.deemo.kidzone.main.Home"), 2, 0);
  }

  public static void enableHome(Context paramContext, PackageManager paramPackageManager)
  {
    paramPackageManager.setComponentEnabledSetting(new ComponentName(paramContext, "com.deemo.kidzone.main.Home"), 1, 1);
  }

 public void onItemClick(AdapterView paramAdapterView, View paramView, int paramInt, long paramLong)
    {
      ApplicationInfo localApplicationInfo = (ApplicationInfo)paramAdapterView.getItemAtPosition(paramInt);
      if (TextUtils.equals(localApplicationInfo.title, Home.this.getString(2131099745)))
      {
        Intent localIntent = new Intent(Home.this, PreferencesProtectionActivity.class);
        Home.this.startActivityForResult(localIntent, 17);
      }
      while (true)
      {
        return;
        if (TextUtils.equals(localApplicationInfo.title, Home.this.getString(2131099746)))
        {
          Home.this.startActivityForResult(new Intent(Home.this, ExitProtectionActivity.class), 16);
          continue;
        }
        Home.this.startActivity(localApplicationInfo.intent);
        Home.lastRunningIntent = localApplicationInfo.intent;
        Logcat.homeLaunched = false;
      }
    }
  }

那么他们是如何在没有 root 的情况下阻止主页按钮的，我该怎么做呢？ http://dl.dropbox.com/u/1928109/kzalvl12.apk 这里是应用程序，我想如果没有市场许可它就无法工作。

将以下内容添加到您的活动中，您也可以发挥作用。无需root电话:)

@Override
public void onAttachedToWindow() {  
    this.getWindow().setType(WindowManager.LayoutParams.TYPE_KEYGUARD);     
    super.onAttachedToWindow();  
}
