android:检测设置(com.android.settings)是否打开 [英] android: detect if settings(com.android.settings) is open

问题描述

我想当用户尝试打开 Settings 应用或包 com.android.settings(Settings 中的所有应用，如电池、wifi、声音等)，它会显示Toast.我将在 Service 中创建.这是我的代码:

i want to when user try to open Settings app or package com.android.settings (all app in Settings like battery, wifi, sound, etc), it will show up Toast. I will create in Service. Here's my code :

public int onStartCommand(Intent intent, int flags, int startId) {
    Toast.makeText(this, " MyService Started", Toast.LENGTH_LONG).show();
    //if(Settings is open){
      //Toast.makeText  . . . 
    } 

    return START_STICKY;
}

我已经在 stackoverflow 中完成了所有操作，但仍然无法正常工作.我为我的英语道歉，如果您提出解决方案，我会很高兴.谢谢你..

I have already all in stackoverflow, but still doesn't work. I apologize for my english, and will be glad if you suggest a solution. Thank You. .

推荐答案

这将获取所有当前正在运行的任务，并循环它们的包名，直到找到(或找不到)您指定的包:

This will get all the currently running tasks, and loop their package names until your specified package is found (or not):

ActivityManager activityManager = (ActivityManager) 
        getSystemService(Context.ACTIVITY_SERVICE);

List<RunningTaskInfo> tasks = activityManager
        .getRunningTasks(Integer.MAX_VALUE);

for (RunningTaskInfo task : tasks) {
    if (task.baseActivity.getPackageName().equalsIgnoreCase("com.android.settings")) {
        Toast.makeText(this, " MyService Started", Toast.LENGTH_LONG).show();
    }               
}

还要将此权限添加到您的清单中:

Also add this permission to your manifest:

<uses-permission android:name="android.permission.GET_TASKS" />
