RecyclerView的项目XML中的Android TextView左重力问题

Question

我有一个 RecyclerViewAdapter，我正在准备一个项目 xml 以将我的所有项目显示为列表。

我的 xml 是这样写的：

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/constraintLayoutAutoCompleteTextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="visible"
    android:background="@drawable/bg_film_add_recycler_view">

    <TextView
        android:id="@+id/textViewFilmName"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:clickable="false"
        android:textSize="16sp"
        android:textColor="@color/figma_text_color_dark"
        android:fontFamily="@font/inter500_regular"
        app:layout_constraintBottom_toBottomOf="@id/imageViewFilmLogo"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@id/imageViewFilmLogo"
        app:layout_constraintTop_toTopOf="@id/imageViewFilmLogo"
        tools:text="MyFilm">
    </TextView>


    <ImageView
        android:id="@+id/imageViewFilmLogo"
        android:layout_width="80dp"
        android:layout_height="30dp"
        android:layout_marginStart="30dp"
        android:layout_marginVertical="10dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent">
    </ImageView>


</androidx.constraintlayout.widget.ConstraintLayout>

因此，我看到我的 RecyclerView 是这样的（红色的是 textviews，绿色的是 imageviews）：

如您所见，文本视图看起来像是在特定区域居中。但我想像这样向左对齐：

我尝试添加android:gravity="left"，但它不起作用，是什么问题？你能帮帮我吗？

如果可能，您能否平衡“布局左边缘 - imageview”和“imageview - textview 左边缘”之间的距离

Answer 1

如果您希望在 constraintLayout 中设置像 layout_gravity="start" 这样的视图行为，请对视图使用 0dp 并且不要忘记为第二个元素添加边距开始

<?xml version="1.0" encoding="utf-8"?>

    android:id="@+id/constraintLayoutAutoCompleteTextView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:visibility="visible"
    android:background="@drawable/bg_film_add_recycler_view">

    <TextView
        android:id="@+id/textViewFilmName"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:clickable="false"
        android:textSize="16sp"
        android:textColor="@color/figma_text_color_dark"
        android:fontFamily="@font/inter500_regular"
        app:layout_constraintBottom_toBottomOf="@id/imageViewFilmLogo"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toEndOf="@id/imageViewFilmLogo"
        app:layout_constraintTop_toTopOf="@id/imageViewFilmLogo"
        tools:text="MyFilm">
    </TextView>


    <ImageView
        android:id="@+id/imageViewFilmLogo"
        android:layout_width="80dp"
        android:layout_height="30dp"
        android:layout_marginStart="30dp"
        android:layout_marginVertical="10dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        app:layout_constraintBottom_toBottomOf="parent">
    </ImageView>


</androidx.constraintlayout.widget.ConstraintLayout>
