在ActivityA中关闭另一个ActivityB android开发

1.对于简单的两个Activity

public class A_activity extends Activity { public static A_activity _instance = null; @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); ..... //重点 _instance = this; } }

public class B_activity extends Activity { @Override protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub super.onCreate(savedInstanceState); A_activity._instance.finish(); } }

2.也可以通过ActivityManager
