取消一个祝酒机器人



我的应用程序在自定义toast中逐个显示所有包名,但问题是,我不希望toast显示在应用程序之外,即当应用程序退出时。我该如何结束我的for循环,或者以某种方式阻止祝酒词出现在onDestroy中?

也许,您可以尝试Snackbar?用户一离开你的应用程序,他们就会被解雇,而且看起来也很酷;(

https://developer.android.com/reference/android/support/design/widget/Snackbar.html

您有许多Toast,因为它们是在循环中创建的。您只需要在onDestroy中取消它们。

...
    mPendingToasts.clear();
    for (int pnum = 0; pnum < procInfos.size(); pnum++) {
        ...
        Toast toast = new Toast(getApplicationContext());
        ...
        mPendingToasts.add(toast);
        toast.show();
    }
}
private ArrayList<Toast> mPendingToasts = new ArrayList<Toast>();
@Override
protected void onDestroy() {
    for(Toast toast:mPendingToasts){
        toast.cancel();
    }
    super.onDestroy();
}

请注意,取消Toast只会阻止它们显示出来。循环中的逻辑(即killing proc(无论如何都会被执行。(即显示Toast是异步的(

是的,无论您想在哪里隐藏吐司,都可以使用toastObject.cancel()方法。

首先将toast作为类的字段,也就是说,在成员函数之外声明。通常我们在它前面加上"m"。之后,你应该我可以这样取消它:

    float x1, x2;
    float y1, y2;

        SharedPreferences settings = getSharedPreferences("prefs", 0);
        boolean firstRun = settings.getBoolean("firstRun", false);
        if (firstRun == false)// if running for first time
        {
            SharedPreferences.Editor editor = settings.edit();
            editor.putBoolean("firstRun", true);
            editor.commit();
