我需要在Kotlin中以编程方式将某些显示配置应用于卡片视图(因为问题是我无法立即在xml中定义它)
这是xml中的此配置(如果可能,我希望能够以编程方式设置相同)
<android.support.v7.widget.CardView
android:id="@+id/resultCard"
android:layout_width="280dp"
android:layout_height="340dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintHorizontal_bias="0.5"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
app:layout_constraintVertical_bias="0.35">
//some other Views inside this CardView
</android.support.v7.widget.CardView>
是否可以通过在Kotlin中进行编码来实现相同的配置?
答案 0 :(得分:0)
要在Kotlin中实现相同的配置,您可以尝试:
val resultCard = findViewById(R.id.resultCard)
val params = resultCard.layoutParams as ConstraintLayout.LayoutParams
params.apply {
startToStart = ConstraintLayout.LayoutParams.PARENT_ID
endToEnd = ConstraintLayout.LayoutParams.PARENT_ID
topToTop = ConstraintLayout.LayoutParams.PARENT_ID
bottomToBottom = ConstraintLayout.LayoutParams.PARENT_ID
horizontalBias = .5f
verticalBias = .35f
}
