通过广播来关闭指定的Activity

setp1:在每个Activity中注册BroadcastReceiver

CloseActivityReceiver closeReceiver = new CloseActivityReceiver();  
IntentFilter intentFilter = new IntentFilter("con.lcry.close.activity");  
registerReceiver(closeReceiver, intentFilter); 

setp2:在当前的Activity中实现内部类,关闭Activity

/** 
 * 实现Activity的广播接收
 * @author LCry
 */     
public class CloseActivityReceiver extends BroadcastReceiver{
    @Override  
    public void onReceive(Context context, Intent intent){  
        xxxActivity.this.finish();  
    }
} 

setp3:在需要关闭Activity时发出广播,告诉对方，我要把你结束

Intent intent = new Intent();  
intent.setAction("con.lcry.close.activity");  
sendBroadcast(intent);
