Question

我正在开发android应用，我想在左侧显示全文，在右侧显示imageview，但textviews不能适合所有屏幕，而imageview根本不能显示

在我的XML下方，其中我已使用constrainlayout实现视图逻辑在我的XML下方，其中我已使用constrainlayout实现视图逻辑

Answer 1

对您的layout_constraintStart_toEndOf="@id/guideline"使用TextView。检查以下布局：

<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="wrap_content">

    <androidx.constraintlayout.widget.Guideline
        android:id="@+id/guideline"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:orientation="vertical"
        app:layout_constraintGuide_percent="0.55" />

    <ImageView
        android:id="@+id/postImage"
        android:layout_width="0dp"
        android:layout_height="0dp"
        android:layout_margin="16dp"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintDimensionRatio="16:9"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintStart_toEndOf="@id/guideline"
        app:layout_constraintTop_toTopOf="parent"
        tools:ignore="ContentDescription" />

    <TextView
        android:id="@+id/userId"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginStart="25dp"
        android:layout_marginLeft="25dp"
        android:layout_marginTop="10dp"
        android:text="Placeholder"
        app:layout_constraintEnd_toStartOf="@+id/guideline"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent" />

    <TextView
        android:id="@+id/postTitle"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:text="Secondary"
        app:layout_constraintEnd_toStartOf="@id/guideline"
        app:layout_constraintStart_toStartOf="@id/userId"
        app:layout_constraintTop_toBottomOf="@id/userId" />

    <TextView
        android:id="@+id/postTime"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="10dp"
        android:text="Tertiary"
        app:layout_constraintStart_toStartOf="@id/userId"
        app:layout_constraintEnd_toStartOf="@id/guideline"
        app:layout_constraintTop_toBottomOf="@id/postTitle" />

    <TextView
        android:id="@+id/postDescription"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="5dp"
        android:layout_marginBottom="10dp"
        android:text="Tertiary"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toStartOf="@id/guideline"
        app:layout_constraintStart_toStartOf="@id/userId"
        app:layout_constraintTop_toBottomOf="@id/postTime" />

</androidx.constraintlayout.widget.ConstraintLayout>

输出：

使用android:justificationMode="inter_word"至TextView
