如何使 Imageview 在 ConstraintLayout 中不与 Textview 重叠

Question

我有问题使这个小部件不相互重叠，我发现如下

（当imageview不可见时预览） （当图像视图可见时预览） 这是我的 xml 片段代码：

<android.support.constraint.ConstraintLayout
        android:id="@+id/constraits"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="5dp">
        <LinearLayout
            android:id="@+id/linearLayout"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:orientation="vertical"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="0.0"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

            <TextView
                android:id="@+id/title_news"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="Tak Ada Nomor Anrean, Masyarakat Sesalkan Pelayanan Kantor Pos Senpokdsoa"
                android:textStyle="bold" />

            <TextView
                android:id="@+id/date_published"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="4 Menit lalu"
                android:textAppearance="@style/Base.TextAppearance.AppCompat.Small"
                android:textStyle="italic" />

        </LinearLayout>

        <ImageView
            android:id="@+id/image_news"
            android:layout_width="wrap_content"
            android:layout_height="70dp"
            android:src="@drawable/sample_headline_img2"
            android:adjustViewBounds="true"
            android:visibility="visible"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintHorizontal_bias="1.0"
            app:layout_constraintStart_toEndOf="@+id/linearLayout"
            app:layout_constraintTop_toTopOf="parent" />

    </android.support.constraint.ConstraintLayout>

有更好的解决方案吗？

试试下面的代码：

<android.support.constraint.ConstraintLayout
        android:id="@+id/constraits"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:paddingBottom="5dp">

            <TextView
                android:id="@+id/title_news"
                android:layout_width="0dp"
                android:layout_height="wrap_content"
                android:text="Tak Ada Nomor Anrean, Masyarakat Sesalkan Pelayanan Kantor Pos Senpokdsoa"
                android:textStyle="bold"
                app:layout_constraintStart_toStartOf="parent"
                app:layout_constraintEnd_toStartOf="@+id/image_news"
                app:layout_constraintTop_toTopOf="parent" />

            <TextView
                android:id="@+id/date_published"
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="4 Menit lalu"
                android:textAppearance="@style/Base.TextAppearance.AppCompat.Small"
                android:textStyle="italic"
                app:layout_constraintStart_toStartOf="@+id/title_news"
                app:layout_constraintTop_toBottomOf="@+id/title_news"
                app:layout_constraintEnd_toStartOf="@+id/image_news" />

        <ImageView
            android:id="@+id/image_news"
            android:layout_width="wrap_content"
            android:layout_height="70dp"
            android:src="@drawable/sample_headline_img2"
            android:adjustViewBounds="true"
            android:visibility="visible"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintTop_toTopOf="parent" />

    </android.support.constraint.ConstraintLayout>

注意：如果您使用的是ConstraintLayout则尝试通过设置视图ConstraintLayout来管理每个视图。 在这里，您使用LinereLayout垂直显示两个TextView ，这可以通过像我一样设置约束来完成。

</android.support.constraint.ConstraintLayout>

Answer 3

完整的实现如下，您可以尝试

<android.support.constraint.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"
tools:context=".MainActivity">

<LinearLayout
    android:layout_width="0dp"
    android:layout_height="150dp"
    android:layout_margin="10dp"
    android:gravity="center_vertical"
    android:orientation="horizontal"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    tools:layout_editor_absoluteY="8dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="5dp"
        android:layout_weight="1"
        android:gravity="center_vertical"
        android:orientation="vertical">

        <TextView
            android:id="@+id/textView4"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginBottom="10dp"
            android:textStyle="bold"
            android:text="Tak Ada Nomor Anrean, Masyarakat Sesalkan Pelayanan Kantor Pos Senpokdsoa"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Small" />

        <TextView
            android:id="@+id/textView3"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="4 Menit lalu"
            android:textAppearance="@style/Base.TextAppearance.AppCompat.Small" />
    </LinearLayout>

    <ImageView
        android:id="@+id/imageView2"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_margin="5dp"
        android:layout_weight="3"
        android:scaleType="center"
        app:srcCompat="@drawable/sample_headline_img2" />
</LinearLayout>

Answer 4

在文本视图中：

<TextView
    android:id="@+id/textView_01"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:text="The text"
    app:layout_constraintEnd_toStartOf="@+id/imageView_01"
    app:layout_constraintHorizontal_bias="0.0"
    app:layout_constraintStart_toStartOf="parent" />

创建从 textView 结尾到 ImageView app:layout_constraintEnd_toStartOf="@+id/imageView_01"开头的约束app:layout_constraintEnd_toStartOf="@+id/imageView_01"

如果您希望文本保持左对齐，请将偏差设置为 0.0。

app:layout_constraintHorizontal_bias="0.0"

关键是确保将宽度设置为 0dp：

android:layout_width="0dp"
