我读了很多类似的问题,但不知道如何解决我的问题。
我在这堂课上收到了来自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();
}
}
我要从那里创建一个alert.dialog
。但是我得到了这个IllegalStateException
。当我记录getApplicationContext()
的字符串时,我得到的是:android.support.multidex.MultiDexApplication@42585d08
我很困在这里,不知道如何解决这个问题。
为完整起见,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;
}

基于标题,听起来好像您在运行代码时所具有的任何Activity都在扩展Activity,并且它需要扩展AppCompatActivity,并且您在res / styles.xml中使用的任何主题都应该是AppCompat主题。
