android - 如何将兄弟 View 限制为与 TextInputLayout 的 TextInputEditText 相同的高度

Question

我想显示带有白色背景的标签“Km”，其高度与编辑文本字段的高度相同。

   <androidx.constraintlayout.widget.ConstraintLayout
            android:layout_width="0dp"
            android:layout_height="match_parent"
            android:layout_weight="1">
            
            <com.google.android.material.textfield.TextInputLayout
                android:id="@+id/textInputLayoutInputDist"
                style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense"
                android:layout_width="wrap_content"
                android:layout_height="42dp"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintTop_toTopOf="parent">

                <com.google.android.material.textfield.TextInputEditText
                    android:id="@+id/inputDist"
                    android:layout_width="80dp"
                    android:layout_height="match_parent"
                    android:background="@drawable/bg_left_corner_shape"
                    android:backgroundTint="@android:color/white"
                    android:fontFamily="@font/roboto_regular"
                    android:imeOptions="actionDone"
                    android:inputType="numberDecimal"
                    android:maxEms="4"
                    android:padding="4dp"
                    android:textColor="@color/colorPrimaryDark"
                    android:textSize="14sp" />
            </com.google.android.material.textfield.TextInputLayout>

            <TextView
                android:id="@+id/label_km"
                android:layout_width="wrap_content"
                android:layout_height="0dp"
                android:layout_marginTop="4dp"
                android:background="@drawable/bg_right_corner_shape"
                android:backgroundTint="@android:color/white"
                android:fontFamily="@font/roboto_regular"
                android:gravity="center_vertical"
                android:text="@string/km"
                android:textColor="@color/colorPrimaryDark"
                android:textSize="14sp"
                app:layout_constraintBottom_toBottomOf="parent"
                app:layout_constraintEnd_toEndOf="parent"
                app:layout_constraintStart_toEndOf="@+id/textInputLayoutInputDist"
                app:layout_constraintTop_toTopOf="@+id/textInputLayoutInputDist" />
        </androidx.constraintlayout.widget.ConstraintLayout>

但 TextInputLayout 的高度比编辑文本字段高，我无法将编辑文本和“Km”标签垂直对齐到同一水平。

As I understand your question check below answer

Give kmLable top and bottom constraint to edit text. Here I give fix width for a temporary purpose (change according to your requirement).
