//在进程中去寻找当前APP的信息,判断是否在前台运行
private boolean isAppOnForeground() {
ActivityManager activityManager =(ActivityManager) getApplicationContext().getSystemService(
Context.ACTIVITY_SERVICE);
String packageName =getApplicationContext().getPackageName();
List<RunningAppProcessInfo>appProcesses = activityManager.getRunningAppProcesses();
if (appProcesses == null )
return false ;
for (RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.processName.equals(packageName)
&& appProcess.importance == RunningAppProcessInfo.IMPORTANCE_FOREGROUND) {
return true ;
}
}
return false ;
}

希望本文所述对大家Android程序设计有所帮助。
