Android編程判斷當前指定App是否在前台的方法

本文實例講述了Android編程判斷當前指定App是否在前台的方法。分享給大家供大家參考，具體如下：

//在進程中去尋找當前APP的信息，判斷是否在前台運行
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;
}

希望本文所述對大家Android程序設計有所幫助。
