Question

我正在创建一个翻译用户文本的应用程序。

首先，我的代码是：

textToReadEdittext.setText(TranslateManager.translate(text, from, to));

现在我需要将翻译后的文本用于其他事情。所以我使用了一个String变量：

String translatedText = TranslateManager.translate(text, from, to);
textToReadEdittext.setText(translatedText);

但现在我的应用程序崩溃了！ Eclipse中有日志：

我不明白为什么我的活动崩溃了。你能救我吗？

Thx，korax。

Answer 1

您的文字或来自或来自null。在传递给TranslateManager之前检查它们，如果它们中的任何一个为空，则将其打印出来。

不可理解的崩溃
