How to determine whether the EditText keyboard input is Chinese or English and how to monitor it

In order to determine whether the EditText keyboard input is Chinese or English, you can use the InputMethodManager class to obtain the current input method information. When switching input methods, you can determine the type of input method by listening to the text change event of EditText. Here is a simple example code:

// 监听EditText的文本改变事件
editText.addTextChangedListener(new TextWatcher() {
    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {
    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {
    }

    @Override
    public void afterTextChanged(Editable s) {
        // 获取当前输入法的信息
        InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
        InputMethodSubtype subtype = imm.getCurrentInputMethodSubtype();

        // 判断输入法的语言类型
        if (subtype.getLanguage().equalsIgnoreCase("zh")) {
            // 当前输入法为中文
        } else {
            // 当前输入法为英文
        }
    }
});

The above code obtains the current input method type when the text of EditText changes, and performs corresponding processing according to the language type. Please note that this is just a basic example, you can perform corresponding logical processing according to actual needs. Hope to help you.
