找不到接受参数且资源链接失败的视图的设置器

问题描述 投票：0回答：1

我被卡在绑定适配器中。后面的适配器不起作用，IDE找不到该适配器。我尝试了许多解决方案，但都没有用。

我尝试了此问题中提供的所有答案，但没有任何效果：Cannot find the setter for attribute with parameter

注意：我有另一个适配器可以将图像加载到同一文件中，并且工作正常。

我想要实现的就是，只要用户在某个editText中输入字符，如果那个editText指定了目标，然后在字符数达到限制后请求目标焦点。

绑定适配器

@BindingAdapter(value = ["destination","limit"])
fun moveToNext(editText: EditText, dest: EditText, limit:Int) {
    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) {
            if (count == limit) {
                dest.requestFocus()
            }
        }

    })
}

我自己弄清楚，问题不在于传递EditText，而是另一个参数

之前

 <EditText
            android:id="@+id/digit_1"
            style="@style/CodDigitEditText"
            android:text=""
            app:layout_constraintEnd_toStartOf="@+id/digit2"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toStartOf="parent"
            android:layout_marginTop="32dp"
            app:layout_constraintTop_toBottomOf="@+id/mobileNumber"
            destination="@{digit2}"
            limit="1"
            />

注意，limit=1的值，这就是问题所在，我只是将其更改为limit="@{1}"，错误消失了

之后

 <EditText
            android:id="@+id/digit_1"
            style="@style/CodDigitEditText"
            android:text=""
            app:layout_constraintEnd_toStartOf="@+id/digit2"
            app:layout_constraintHorizontal_bias="0.5"
            app:layout_constraintStart_toStartOf="parent"
            android:layout_marginTop="32dp"
            app:layout_constraintTop_toBottomOf="@+id/mobileNumber"
            destination="@{digit2}"
            limit="@{1}"
            />
