我的安卓游戏中有问题。我使用AsyncTask并在onProgressUpdate中从活动类调用Static方法。像这样:
protected void onProgressUpdate(Message... values) {
super.onProgressUpdate(values);
OnlineGameActivity.refreshGame(values[0]);
}
然后在onlineGameActivity方法中,我需要调用一些其他非静态方法来提升游戏状态,例如:
public class OnlineGameActivity extends Activity {
public static void refreshGame(Message message) {
switch (message.getType()) {
case 1:
methode1();
break;
case 2:
methode2();
break;
case 3:
methode3();
break;
}
有可能做到这样吗?

是。您可以将os.Handler
实例传递给AsyncTask
,然后向其发送空消息。类似于以下内容:
public class OnlineGameActivity extends Activity {
Handler myHandler = new Handler() {
@Override
public void handleMessage(Message msg) {
switch (msg.what) {
case 0:
...
break;
...
}
}
}
public OnlineGameActivity(...) {
...
YourAsyncTask task = new YourAsyncTask(myHandler);
task.execute();
}
}
和您的AsyncTask
:
public class YourAsyncTask extends AsyncTask<...> {
Handler myHandler;
public YourAsyncTask(Handler myHandler) {
this.myHandler = myHandler;
}
...
@Override
protected void onProgressUpdate(Message... values) {
myHandler.sendEmptyMessage(values[0]);
}
}
