1.在自定义的Application中添加下面代码，在其它类中直接使用即可。

private static MapdestroyMap = new HashMap<>();

/**

* 添加到销毁队列

*

* @param activity 要销毁的activity

*/

public static void addDestroyActivity(Activity activity, String activityName) {

destroyMap.put(activityName, activity);

}

/**

* 销毁指定Activity

*/

public static void destroyActivity(String activityName) {

SetkeySet = destroyMap.keySet();

if (keySet.size() > 0) {

for (String key : keySet) {

if (activityName.equals(key)) {

destroyMap.get(key).finish();

}

}

}

}

2.使用

AActivity.class

/**

* Created by mythmayor on 2017/3/31.

*/

public class AActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_a);

MainApplication.addDestroyActivity(this, "AActivity");

}

}

BActivity.class

/**

* Created by mythmayor on 2017/3/31.

*/

public class BActivity extends Activity {

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_b);

MainApplication.destroyActivity("AActivity");

}

}
