Android 4.3。 这是我的xml layuout:
<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">
<ImageView
android:id="@+id/imageViewPhoto"
android:layout_width="match_parent"
android:layout_height="@dimen/card_height"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<ImageView
android:id="@+id/imageViewFavorite"
android:layout_width="28dp"
android:layout_height="28dp"
android:src="@drawable/ic_like_inactive"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/titleTextView"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintEnd_toStartOf="@+id/imageViewDownload"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toBottomOf="@+id/imageViewPhoto" />
<TextView
android:id="@+id/subTitleTextView"
android:layout_width="0dp"
android:layout_height="wrap_content"
app:layout_constraintEnd_toEndOf="@+id/titleTextView"
app:layout_constraintLeft_toLeftOf="@+id/titleTextView"
app:layout_constraintTop_toBottomOf="@+id/titleTextView" />
<ImageView
android:id="@+id/imageViewDownload"
android:layout_width="28dp"
android:layout_height="28dp"
app:layout_constraintBottom_toBottomOf="@+id/subTitleTextView"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintTop_toTopOf="@+id/titleTextView"
app:srcCompat="@drawable/ic_download_inactive" />
</android.support.constraint.ConstraintLayout>
结果如下:
我想在Android 4.3的顶部和底部添加半径角。我怎么能这样做?您可以在顶部看到 imageView ,并且在底部有 textView 。
也许使用drawable?
P.S。 CardView 无济于事,因为它无法在Android 4.3上运行。
