调整软键盘输入上方的android布局

Question

我有一个使用约束布局的视图。该视图有一个编辑文本，并希望显示软键盘输入。屏幕底部有两个按钮（上一个和下一个）。当软键盘打开时，两个按钮隐藏在键盘后面。但是，我希望布局调整大小，以便按钮位于软键盘上方而不是在其后面。 我的清单中有以下内容。

   <activity
        android:name=".activity.SomeActivity"
        android:screenOrientation="portrait"
        android:windowSoftInputMode="adjustResize">
    </activity>

我查看了其他各种帖子并尝试了一些不同的东西，例如adjustPan。我已经设置了

android:fitsSystemWindows="true"

但是他们两个都没有工作。

我的约束布局如下所示。

EditText 以编程方式添加。

 var editText = CustomEditText(context)
        editText.apply {
            id = View.generateViewId()
            layoutParams = ConstraintLayout.LayoutParams(ConstraintLayout.LayoutParams.MATCH_PARENT, ConstraintLayout.LayoutParams.WRAP_CONTENT)
            setSingleLine(true)
            imeOptions = EditorInfo.IME_ACTION_DONE
            val questionType = question.validation?.type
            if (questionType == Validation.Type.INTEGER) {
                inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_SIGNED
            } else if (questionType == Validation.Type.NUMBER) {
                inputType = InputType.TYPE_CLASS_NUMBER or InputType.TYPE_NUMBER_FLAG_SIGNED or InputType.TYPE_NUMBER_FLAG_DECIMAL
            } else if (questionType == Validation.Type.MRN) {
                inputType = InputType.TYPE_CLASS_NUMBER
                filters = arrayOf(InputFilter.LengthFilter(9))
            } else if (questionType == Validation.Type.ZIP_CODE) {
                inputType = InputType.TYPE_CLASS_PHONE
                filters = arrayOf(InputFilter.LengthFilter(10))
            } else if (questionType == Validation.Type.PHONE) {
                inputType = InputType.TYPE_CLASS_NUMBER
                editText.setSelection(editText.text?.length!!)
                editText.addTextChangedListener(PhoneFormatterTextWatcher(editText))
            }
            tag = TAG_FOCUS_FIRST
        }
        editText.setText(question.value ?: "")
        if (question.validation?.type == Validation.Type.ZIP_CODE) {
            editText.addTextChangedListener(ZipCodeTextWatcher(editText, question, updateCallback))
        } else {
            editText.addTextChangedListener(object : TextWatcher {
                override fun afterTextChanged(s: Editable?) {
                    //
                }

                override fun beforeTextChanged(s: CharSequence?, start: Int, count: Int, after: Int) {
                    //
                }

                override fun onTextChanged(s: CharSequence?, start: Int, before: Int, count: Int) {
                    question.value = if (s != null && s.isNotBlank()) s.toString() else null
                    updateCallback()
                }

            }
            )
        }
        editText.setOnEditorActionListener() { v, actionId, event ->
            if (actionId == EditorInfo.IME_ACTION_DONE) {
                doneCallback()
                true
            } else {
                false
            }
        }

        return editText

这是将此视图添加到输入容器的代码

inputContainer.addView(editText)

您的 EditText 视图在哪里？我认为您必须了解约束布局。你怎么能尝试这个xml布局代码.. 为视图添加样式。
