Firebase java.lang.IollegalStateException:您需要在此活动中使用Theme.Ap

Question

我读过很多类似的问题，但不知道如何解决我的问题。

我在这门课上收到了来自firebase的云消息通知：

public class FirebaseMessagingServiceImpl extends FirebaseMessagingService {
private final static String TAG = "FirebaseMessaging";
@Override
public void onMessageReceived(RemoteMessage remoteMessage) {
Log.i(TAG, "Message from " + remoteMessage.getFrom());
if (remoteMessage.getNotification() != null) {
final String content = remoteMessage.getNotification().getBody();
final String title = remoteMessage.getNotification().getTitle();
Log.i(TAG, "...with content: " + content);
new Handler(Looper.getMainLooper()).post(new Runnable() {
@Override
public void run() {
UserInterfaceUtils.getAlertDialog(
getApplicationContext(),
title,
content,
android.R.string.ok,
android.R.string.no,
android.R.drawable.ic_dialog_alert,
null, null,
true, false).show();
}
});
}
super.onMessageReceived(remoteMessage);
}
@Override
public void onDeletedMessages() {
super.onDeletedMessages();
}
}

从那里我想创建一个alert.dialog。但我得到了这个IllegalStateException。当我记录getApplicationContext()的字符串时，我得到的是：android.support.multidex.MultiDexApplication@42585d08

我被困在这里，不知道如何解决这个问题。

为了完整起见，我的getAlertDialog方法：

public static AlertDialog.Builder getAlertDialog(Context context, String title, String message, int pos, int neg, int icon, final Callable posFunc, final Callable negFunc, boolean posButton, boolean negButton) {
AlertDialog.Builder builder;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
builder = new AlertDialog.Builder(context, R.style.ShopDialogTheme);
} else {
builder = new AlertDialog.Builder(context);
}
builder.setTitle(title)
.setMessage(Html.fromHtml(message));
if (posButton)
builder.setPositiveButton(pos, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
try {
posFunc.call();
} catch (Exception e) {
e.printStackTrace();
}
}
});
if (negButton)
builder.setNegativeButton(neg, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
try {
negFunc.call();
} catch (Exception e) {
e.printStackTrace();
}
}
});
builder.setCancelable(false);
builder.setIcon(icon);
return builder;
}

根据标题，当您的代码运行时，听起来任何"活动"都是在扩展"活动"，它需要扩展AppCompatActivity，而无论您在res/styles.xml中使用什么主题，您的活动都应该是AppCompat主题。
