在应用(Kotlin)的同一页面上用TextView创建多组加号和减号按钮

<LinearLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical">

    <TextView
        android:id="@+id/resultTextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="0" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

        <Button
            android:id="@+id/increaseButton1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="+" />

        <TextView
            android:id="@+id/counterTextView1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="0" />

        <Button
            android:id="@+id/decreaseButton1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="-" />

    </LinearLayout>

    <!-- 添加更多的按钮组 -->

</LinearLayout>

class MainActivity : AppCompatActivity() {
    private lateinit var resultTextView: TextView

            if (counter1 > 0) {
                counter1--
                counterTextView1.text = counter1.toString()
                updateResult()
            }
        }
    }

    private fun updateResult() {
        val total = counter1 // 计算总数，可以根据实际需求进行修改
        resultTextView.text = total.toString()
    }
}
