处理activity销毁的问题

Posted 2022-12-10 cgtcsdn

//用于解决：杀死存在于进程中的某个Activity

if(ChatActivity.activityInstance != null)

ChatActivity.activityInstance.finish();

ActivityManager mActivityManager = (ActivityManager) GroupDetailsActivity.this.getSystemService(Context.ACTIVITY_SERVICE);  

// 存放Activity Task的集合

List<RunningTaskInfo> list = mActivityManager.getRunningTasks(100);

for (RunningTaskInfo info : list)

// 判断进程中的Activity类名是否等于某个Activity的类名，条件成立，则杀死该Activity

if (info.topActivity.getPackageName().equals(TeamMapActivity.activityInstance.getPackageName())

&&info.baseActivity.getPackageName().equals(TeamMapActivity.activityInstance.getPackageName()))

TeamMapActivity.activityInstance.finish();// 关闭，activityInstance用来标志TeamMapActivity（某Activity）的实例
  break;
 
 

// 所需权限

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