如何在高度为 wrap_content 的图像视图上添加文本视图叠加层
How to add a textview overlay on an imageview which has hieght of wrap_content
你好,我有一个问题,我将文本视图添加为图像视图上的叠加层,图像视图的高度为 wrap_content,宽度为 match_parent(我不想更改高度或宽度图像视图的任何成本)问题是文本没有显示
the scaleType i have included to the imageView is fitCenter (From
Glide)
这是我的代码
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<com.google.android.material.card.MaterialCardView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_centerInParent="true"
android:layout_marginStart="5dp"
android:layout_marginTop="11dp"
android:layout_marginEnd="5dp"
app:cardElevation="1dp"
app:cardMaxElevation="4dp"
app:shapeAppearanceOverlay="@style/RoundedCorner">
<RelativeLayout
android:layout_width="wrap_content"
android:layout_height="wrap_content">
<TextView
android:id="@+id/rankedNumber"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_marginStart="20dp"
android:layout_marginTop="20dp"
android:background="@drawable/circular_background_text"
android:text="@string/_1"
android:textAlignment="center"
android:textColor="@color/black"
android:textSize="40sp"
android:textStyle="italic" />
<com.google.android.material.imageview.ShapeableImageView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:contentDescription="@string/todo" />
</RelativeLayout>
</com.google.android.material.card.MaterialCardView>
</RelativeLayout>
试试这个,在你的 CardView
:
<FrameLayout
android:layout_width="match_parent"
android:layout_height="wrap_content">
<com.google.android.material.imageview.ShapeableImageView
android:id="@+id/imageView"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:adjustViewBounds="true"
android:contentDescription="@string/todo" />
<TextView
android:id="@+id/rankedNumber"
android:layout_width="wrap_content"
android:layout_gravity="center"
android:layout_height="wrap_content"
android:layout_alignParentStart="true"
android:layout_marginStart="20dp"
android:layout_marginTop="20dp"
android:background="@drawable/circular_background_text"
android:text="@string/_1"
android:textAlignment="center"
android:textColor="@color/black"
android:textSize="40sp"
android:textStyle="italic" />
</FrameLayout>
