Question

这是我的代码和图片我有轮播recyclerview的地方，每个项目都有很长的文字如何剪切文本并使文本与imageView的结尾对齐？

<androidx.constraintlayout.widget.ConstraintLayout xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/layout_container"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_margin="4dp">

    <ImageView
        android:id="@+id/asset_image"
        android:layout_width="120dp"
        android:layout_height="100dp"
        android:scaleType="centerCrop"
        app:imageUrl="@{imageUrl}"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        tools:layout_conversion_wrapHeight="0"
        tools:layout_conversion_wrapWidth="0" />

    <TextView
        android:id="@+id/tv_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:ellipsize="end"
        android:maxLines="1"
        android:text="sfsdfsdfsjkfljljljljlklkjlkjkhksdjfskdjflsdjflsdjkflsjkdf"
        app:layout_constraintEnd_toEndOf="@+id/asset_image"
        app:layout_constraintStart_toStartOf="@+id/asset_image"
        app:layout_constraintTop_toBottomOf="@+id/asset_image" />
</androidx.constraintlayout.widget.ConstraintLayout>

Answer 1

1。设置文本视图宽度以匹配约束（0dp）

2。将TextView的右/ letf约束设置为ImageView的右/左

 <?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:layout_width="match_parent"
        android:layout_height="match_parent">

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="250dp"
            tools:src="@tools:sample/avatars"
            android:layout_height="250dp"   
            android:layout_marginStart="8dp"
            android:layout_marginEnd="8dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent" />

        <TextView
            android:id="@+id/texts"
            android:layout_width="0dp"
            android:layout_height="wrap_content"
            tools:text="@tools:sample/lorem/random"
            app:layout_constraintEnd_toEndOf="@+id/imageView"
            app:layout_constraintStart_toStartOf="@+id/imageView"
            app:layout_constraintTop_toBottomOf="@+id/imageView" />

    </androidx.constraintlayout.widget.ConstraintLayout>

Answer 2

您必须给您的textview width = "match_constraint"基本上等于0dp，这样您的textview width将等于您在结尾处设置的约束textview：

<TextView
    android:id="@+id/tv_title"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:ellipsize="end"
    android:maxLines="1"
    android:text="sfsdfsdfsjkfljljljljlklkjlkjkhksdjfskdjflsdjflsdjkflsjkdf"
    app:layout_constraintEnd_toEndOf="@+id/asset_image"
    app:layout_constraintStart_toStartOf="@+id/asset_image"
    app:layout_constraintTop_toBottomOf="@+id/asset_image" />

只需将android:layout_width="wrap_content"更改为android:layout_width="120dp"

如何对齐以顶视图（ImageView）结尾的文本并从头开始切割文本？
