Android 编辑列表中的文本。EditText.TextChanged在滚动条上给出了错误的值

我在每个列表上都有以下行布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal"
    android:layout_width="match_parent"
    android:layout_height="wrap_content">
    <TextView
        android:id="@+id/RawNumberTextView"
        android:layout_marginLeft="@dimen/ButtonMargin"
        android:layout_marginRight="@dimen/ButtonMargin"
        android:text="@string/ColumnsStatistics_RawCount"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>
    <EditText
        android:id="@+id/RawBetEditText"
        android:clickable="true"
        android:focusable="true" 
        android:focusableInTouchMode="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_weight="1"
        android:inputType="number"/>
            <com.google.android.material.button.MaterialButton
            style="@style/AppTheme.ButtonStyle"
        android:id="@+id/MinusOneButton"
        android:layout_marginLeft="@dimen/ButtonMargin"
        android:layout_marginRight="@dimen/ButtonMargin"
            android:elevation="@dimen/ButtonElevation"
            android:text="-1"        
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
              />
            <com.google.android.material.button.MaterialButton
            style="@style/AppTheme.ButtonStyle"
        android:id="@+id/PlusOneButton"
        android:layout_marginRight="@dimen/ButtonMargin"
            android:elevation="@dimen/ButtonElevation"
            android:text="+1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
             />
</LinearLayout>

您可以在加号或减号时再次设置编辑文本的

Data[pos]

值

将下面的代码添加到加号或减号按钮事件中

 Data[pos] = betPerDrawEditText.Text;

整个代码：

            MinusOneButton.Click += (sender, e) =>
            {
                pos = (int)MinusOneButton.Tag;
                Data[pos] = betPerDrawEditText.Text;
                int number = 0;

                bool success = int.TryParse(Data[pos], out number);
                if (success)
                {
                    if (number > 0)
                        number--;
                    Data[pos] = number.ToString(CultureInfo.InvariantCulture);
                    betPerDrawEditText.Text = number.ToString(CultureInfo.InvariantCulture);
                }
                else
                {
                    Data[pos] = number.ToString(CultureInfo.InvariantCulture);
                    betPerDrawEditText.Text = number.ToString(CultureInfo.InvariantCulture);
                }
            };

            PlusOneButton.Click += (sender, e) =>
            {
                pos = (int)PlusOneButton.Tag;
                int number = 1;
                Data[pos] = betPerDrawEditText.Text;
                bool success = int.TryParse(Data[pos], out number);
                if (success)
                {
                    number++;
                    betPerDrawEditText.Text = number.ToString(CultureInfo.InvariantCulture);
                    Data[pos] = number.ToString(CultureInfo.InvariantCulture);
                }
                else
                {
                    betPerDrawEditText.Text = number.ToString(CultureInfo.InvariantCulture);
                    Data[pos] = number.ToString(CultureInfo.InvariantCulture);
                }
            };

您好，谢谢您的回答，我也用一个代码编辑了这个问题，这个代码也可以使用，但是有东西告诉我，它被多次无缘无故地访问，而您的想法更好，您认为呢？在我给出答复之前，我尝试了

TextChanged

。它访问了很多次。我提供的方法运行良好，没有错误。因此，我提供了在加号或减号之前设置

数据[pos]

的方法。虽然您的代码在按钮上运行良好，但如果我从键盘上更改整数并向下滚动，则不会存储输入，因此我还添加了以下代码：betPerDrawEditText.TextChanged+=（object sender，Android.Text.TextChangedEventArgs e）=>{int number=0；if（（int）betperpaudedittext.Tag==position）{bool success=int.TryParse（e.Text.ToString（），out number）；if（success）Data[position]=number.ToString（）；}；如果此回复对您有帮助，您可以接受作为答案。如果您在更改键盘上的整数并向下滚动时遇到问题，请发布带有代码和错误的新问题。在您的代码中，您没有关于EditText的任何信息。TextChanged，当输入来自键盘时，您如何保存更改的内容？您的代码仅显示减号+按钮的内容ns有
