将信息从 EditText 发送到 IME
我正在编写一个语言学习应用程序，目前只有德语<->俄语。
有几个 EditTexts，用户应该在其中以一种或另一种语言输入文本。由于这些语言使用不同的字母表，因此应用程序通过实现 InputMethodService 并提供拉丁语和西里尔语键盘布局来使用自己的软键盘。每个 EditText 字段都知道需要哪种语言。
我想要的是，例如，每当需要俄语的 EditText 字段处于焦点时，就应该显示西里尔字母键盘布局。选择后，EditText 应将一些常量传递给 IME，后者可使用该常量来决定是否以拉丁语或西里尔语模式显示。
理想情况下，只需为 EditText 指定一些自定义 InputType，但这似乎不可能，不是吗？这里正确的做法是什么？
I'm writing a language learning app, currently only German<->Russian.
There are several EditTexts where the user is supposed to enter text in one or the other language. As these languages use different alphabets, the app uses its own soft keyboard by implementing InputMethodService and providing both Latin and Cyrillic keyboard layout. It is known for each EditText field which language is expected.
What I would like is that, e.g., whenever an EditText field expecting Russian is in focus, the Cyrillic keyboard layout should be displayed. When selected, the EditText should pass some constant on to the IME, which the latter can use to decide whether to display in Latin or Cyrillic mode.
Ideally, one would simply specify some custom InputType for the EditText but that doesn't seem to be possible, does it? What is the correct approach here?

你的想法听起来不错。 IME 的代码检查开关块中的
InputType，如果InputType不匹配，则显示默认键盘布局。您还可以在
Activity的onCreate()方法中提供逻辑，以检查哪个输入法处于活动状态，并根据该信息选择您的inputTypeEditText应该有。Your idea doesn't sound bad. IME's code check for the
InputTypein a switch block and the default keyboard layout is shown if theInputTypedidn't match.You can also provide a logic in
onCreate()method of yourActivityto check which input method is active and with that info choose whichinputTypeyourEditTextshould have.
