我是用我的活动moveTaskToBack（）方法。

当我是pressing后退按钮的活动仍是可见的。 BACK键不起作用。我做了什么错在这里？我想导航回到previous活动。

 公共无效onBack pressed（）{
    // TODO自动生成方法存根
    moveTaskToBack（真正的）;
    新的终结（）killApp（假）;
    super.onBack pressed（）;
}
 

解决方案

moveTaskToBack的目的：

http://developer.android.com/reference/android/app/ Activity.html

moveTaskToBack（布尔非root）

移到含有该活动到活动堆后面的任务

你可以做的是：

 公共无效onBack pressed（）{
    // TODO自动生成方法存根
    moveTaskToBack（真正的）; //我不认为你正在寻找这一点。
    新的终结（）killApp（假）; //无论这一点。
    super.onBack pressed（）;
}
 

也许这样的：安卓：回到previous活动 一些在类似的 onBack pressed（）在 super.OnBack pressed（）; 另外，还要确保当你打你的后退按钮，你真的要在这个方法中。

I am using moveTaskToBack() method in my activity.

When I am pressing back button the activity still is visible. The back key does not work. What did I do wrong here? I want to navigate back to the previous activity.

public void onBackPressed() {
    // TODO Auto-generated method stub
    moveTaskToBack(true);
    new Finalizer().killApp(false);
    super.onBackPressed();
}

The purpose of moveTaskToBack:

http://developer.android.com/reference/android/app/Activity.html

moveTaskToBack(boolean nonRoot)

Move the task containing this activity to the back of the activity stack.

What you could do is:

public void onBackPressed() {
    // TODO Auto-generated method stub
    moveTaskToBack(true); // I don't think you're looking for this.
    new Finalizer().killApp(false); // Neither this.
    super.onBackPressed();
}

Maybe this: Android: Go back to previous activity Something similar in your onBackPressed() after super.OnBackPressed(); Also make sure when you're hitting your back button, you're actually going in this method.
