EditText 或 InputText 不起作用，创建输入法以随机获取字符串

Question

我构建了一个在应用程序外部具有浮动按钮的 android 应用程序（例如 Facebook 聊天头信使。问题是当我单击 EditText 或 TextInputEditText 时它没有显示键盘。 我是 android 新手，我不知道我是否可以在应用程序之外执行此操作。但我确信当点击edittext以捕捉键盘上输入的浮点数或字符串时，有一种方法可以打开键盘。 如果有一个解决方案可以让真正的 EditText 在服务中工作，那就太棒了。

 @Override
public void onCreate() {
    super.onCreate();

    //getting the widget layout from xml using layout inflater
    mFloatingView = LayoutInflater.from(this).inflate(R.layout.widget_layout, null);

    final WindowManager.LayoutParams params;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.O) {
        params = new WindowManager.LayoutParams(
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.WRAP_CONTENT,
                WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
                WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
                PixelFormat.TRANSLUCENT);
    } else {
        params = new WindowManager.LayoutParams(

“WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE”可能是原因，因为该键盘来自操作系统本身，您不需要触发任何东西，但是您禁用聚焦将阻止该文本框或输入框获得焦点，这将导致“键盘不显示”
