如何在“约束文本”中的所有元素上移至“编辑文本”字段的焦点?

我正在尝试使用“编辑文本”字段进行布局以处理电子邮件请求。该设计使键盘始终在editText视图上打开,从而使您无法知道所输入的内容。我已经尝试了很多关于堆栈溢出的建议,但是大多数建议都是针对API <24的(尽管我认为这对此没有太大影响)。

在“活动”文件中,我尝试了以下操作:

window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN or WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN)

window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN)

window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN or WindowManager.LayoutParams.SOFT_INPUT_ADJUST_PAN)


window.setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE)

在Android清单中,我还结合或单独尝试了以下方法:

android:windowSoftInputMode="adjustPan"
android:windowSoftInputMode="stateHidden|adjustPan"
android:windowSoftInputMode="adjustResize"

我还按照Heena的描述将布局包裹在ScrollView中  此处:https://stackoverflow.com/a/39867438/5635144

        auth = FirebaseAuth.getInstance()



        val animDrawable = resetPassInfoBg.background as AnimationDrawable
        animDrawable.setEnterFadeDuration(2500)
        animDrawable.setExitFadeDuration(1500)
        animDrawable.start()


        sendRequestBtn.setOnClickListener(View.OnClickListener {
            val email = e_request.getText().toString().trim()

            if (TextUtils.isEmpty(email)) {
                Toast.makeText(application, "Enter your email ", Toast.LENGTH_SHORT).show()
                return@OnClickListener
            }


        })


    }

}

我希望将布局向上移动,以使editText字段可见,但目前没有任何方法使它起作用。

Remove this line:

window.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS)

With FLAG_LAYOUT_NO_LIMITS the application is not able to calculate how to scroll your view, because your layout has no limits.
