Question

我的xml文件使用约束布局，使用依赖项'com.android.support.constraint:constraint-layout:1.0.0-beta4'

，文本无法正确包装

<?xml version="1.0" encoding="utf-8"?>
<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    xmlns:tools="http://schemas.android.com/tools">

    <ImageView
        android:layout_width="254dp"
        android:layout_height="100dp"
        app:srcCompat="@mipmap/ic_launcher"
        android:id="@+id/thumbnail_image_view"
        android:layout_marginTop="16dp"
        android:scaleType="centerCrop"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginStart="16dp"
        app:layout_constraintLeft_toLeftOf="parent"
        android:layout_marginLeft="16dp" />

    <TextView
        tools:text="name of the movie"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/original_title"
        android:layout_marginTop="8dp"
        app:layout_constraintTop_toBottomOf="@+id/thumbnail_image_view"
        app:layout_constraintLeft_toLeftOf="@+id/thumbnail_image_view" />

    <TextView
        tools:text="ReleaseDate"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/release_date"
        android:layout_marginTop="8dp"
        app:layout_constraintTop_toBottomOf="@+id/original_title"
        app:layout_constraintLeft_toLeftOf="@+id/original_title" />

    <TextView
        tools:text="Ratings"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/user_rating"
        android:layout_marginTop="8dp"
        app:layout_constraintTop_toBottomOf="@+id/release_date"
        app:layout_constraintLeft_toLeftOf="@+id/release_date" />

    <Button
        tools:text="Favourite"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/fav_btn"
        android:layout_marginTop="96dp"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginEnd="16dp"
        app:layout_constraintRight_toRightOf="parent"
        android:layout_marginRight="16dp"
        android:onClick="addToFav"/>

    <TextView
        tools:text="ConstraintLayout allows you to create large and complex layouts with a flat view hierarchy (no nested view groups). It's similar to RelativeLayout in that all views are layed out according to relationships between sibling views and the parent layout, but it's more flexible than RelativeLayout and easier to use with Android Studio's Layout Editor.
        Everything you can do with ConstraintLayout is available directly from the Layout Editor's visual tools, because the layout API and the Layout Editor were specially built for each other. So you can build your layout with ConstraintLayout entirely by drag-and-dropping instead of editing the XML."
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/synopsis"
        app:layout_constraintRight_toRightOf="@+id/fav_btn"
        app:layout_constraintLeft_toLeftOf="@+id/user_rating"
        android:layout_marginTop="16dp"
        app:layout_constraintTop_toBottomOf="@+id/user_rating"
        app:layout_constraintHorizontal_bias="0.0" />

</android.support.constraint.ConstraintLayout>

设计视图如下所示：

Answer 1

在布局的每个组件中设置填充，例如：

 <Button
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:padding="10dp"
            android:text="@string/plus" />

试试这个。

Answer 2

答案是错误的。您应该为textView设置约束，而不要使用“ wrap_content”

Android约束布局会切断textview中的文本
