Android打字完成后，如何将多行编辑文本限制为单行？

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="text" />

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:maxLines="1" />

InputFilter filter = new InputFilter() {
    public CharSequence filter(CharSequence source, int start, int end,
            Spanned dest, int dstart, int dend) {
        // 过滤掉换行符和回车符
        for (int i = start; i < end; i++) {
            if (source.charAt(i) == '\n' || source.charAt(i) == '\r') {
                return "";
            }
        }
        return null; // 保持原样
    }
};

EditText editText = findViewById(R.id.editText);
editText.setFilters(new InputFilter[]{filter});
