android多activity下如何退出整个程序

尝试过System.exit(0)和android.os.Process.killProcess(android.os.Process.myPid())两种方法都失败了。这两个应该均只能退出单activity

最后终于找到一个相对靠谱的方法，即重写activity，通过broadcast的方法解决这个问题。方法如下：

public class BaseActivity extends Activity {

public Activity aty;

public ExitAllBroadCast exitAllBroadCast;

/** Called when the activity is first created. */

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

aty = BaseActivity.this;

exitAllBroadCast = new ExitAllBroadCast();

}

/* (non-Javadoc)

* @see android.app.Activity#onStart()

*/

@Override

protected void onStart() {

IntentFilter filter = new IntentFilter();// 创建IntentFilter对象

filter.addAction("com.kg.exit.broadcast");

registerReceiver(exitAllBroadCast, filter);// 注册Broadcast Receiver

super.onStart();

}

class ExitAllBroadCast extends BroadcastReceiver{

@Override

public void onReceive(Context context, Intent intent) {

// TODO Auto-generated method stub

aty.finish();

}

}

@Override

protected void onDestroy() {

// TODO Auto-generated method stub

super.onDestroy();

unregisterReceiver(exitAllBroadCast);

}

}

直接贴过来了，需要调用退出的部分：

Intent myIntent = new Intent();// 创建Intent对象

myIntent.setAction("com.kg.exit.broadcast");

sendBroadcast(myIntent);// 发送广播

即可。有关全局变量，我只能在退出时调用OnCreate方法恢复初始值，其他的暂时还没有找到更好的方法。
