所需资源：android

2018年的时候，为了解决如下问题而自定义了一个activity管理类：

当关闭apk的时候关闭所有的activity获取顶部activity获取mainActivity或其他指定类关闭出指定activity之外的其他activity

主要函数：

private static MyApplication instance;
private Context context;
private Map<String, Activity> activityMap = new HashMap<String, Activity>();

@Override
public void onCreate() {
    super.onCreate();
    srcTable = new ArrayList<HashMap<String, Object>>();
}

// 添加Activity 到容器中
public void addActivity(String className, Activity activity) {
    activityMap.put(className, activity);
}

// 遍历所有Activity 并finish
public void exit() {
    for (Entry<String, Activity> entry : activityMap.entrySet()) {
        entry.getValue().finish();
    }
    System.exit(0);
}

管理类:

import java.util.LinkedList;

import java.util.List;

  

import android.app.Activity;

  

  /**

 * @author liguoshuai

 * @category 页面管理

 */

  public class AppActivityList {

   private List<Activity> activityList = new LinkedList<Activity>();

  

   // 添加Activity 到容器中

   public void addActivity(Activity newActivity) {

      for (Activity activity : activityList) {

         boolean same = activity.toString().contentEquals(newActivity.toString());

         if (same) {

            activityList.remove(activity);

            break;

         }

      }

      activityList.add(newActivity);// 重新加入到尾部

   }

  

   public Activity getTopActivity() {

      Activity topActivity = null;

      int lastPos = activityList.size() - 1;

      if (lastPos >= 0) {

         topActivity = activityList.get(lastPos);

      }

      return topActivity;

   }

  

   public void finishAll() {

      for (Activity activity : activityList) {

         if (activity != null) {

            activity.finish();

         }

      }

   }

  

   public void resetActivity(Activity except) {

      for (Activity activity : activityList) {

         boolean same = activity.toString().contentEquals(except.toString());

         if (!same) {

            if (activity != null) {

               activity.finish();

            }

         }

      }

   }

  

   public Activity getMainActivity() {

      for (Activity activity : activityList) {

         if (activity.getClass().getSimpleName().contentEquals("MainActivity")) {// singleton

            return activity;

         }

      }

      return null;

   }

  

   public Activity getLoginActivity() {

      for (Activity activity : activityList) {

         if (activity.getClass().getSimpleName().contentEquals("LoginActivity")) {// singleton

            return activity;

         }

      }

      return null;

   }

  

   public void removeActivity(Activity removeActivity) {

      int index = 0;

      for (Activity activity : activityList) {

         boolean same = activity.toString().contentEquals(removeActivity.toString());

         if (same) {

            break;

         }

         index++;

      }

      activityList.remove(index);

  

   }

  

   public void removeActivity(String activityName) {

      for (Activity activity : activityList) {

         if (activity == null)

            continue;

         String className = activity.getClass().getSimpleName();

         if (className.contentEquals(activityName)) {

            activity.finish();

         }

      }

   }

}

应用，创建一个基类包装对应功能：

import android.app.Activity;import android.content.pm.ActivityInfo;import android.content.res.Configuration;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.support.v4.app.FragmentActivity;/** * @author liguoshuai @category */public class BaseActivity extends FragmentActivity implements Handler.Callback { public BaseActivity thisActivity; protected Handler mHandler; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); thisActivity = this;// 窗口上下文 mHandler = new Handler(this); MyApplication.getActivityList().addActivity(this);// 1 } @Override protected void onDestroy() { // MyLog.i(TAG, " destroy!"); MyApplication.getActivityList().removeActivity(this);// 1 super.onDestroy(); // Always call the superclass } @Override public void onConfigurationChanged(Configuration newConfig) { super.onConfigurationChanged(newConfig); if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE) { setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT); } else { } } @Override public void onResume() { SoftInput.hideSoftInput(thisActivity); super.onResume(); } // 实现消息处理 public Handler getMsgHandler() { return mHandler; } @Override public boolean handleMessage(Message msg) { switch (msg.what) { } return false; }}
