如何解决海拔在 PopupWindow Android 中不起作用
我在我的 android 应用程序中使用 PopupWindow
并且它工作正常。但是我必须向它添加 elevation
但它不起作用。这是我的做法
查看以显示在弹出窗口 popup_view_order_status
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:background="@color/white"
android:layout_margin="@dimen/margin_xlarge"
android:elevation="@dimen/margin_large"
android:padding="@dimen/margin_large">
<TextView
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:textSize="@dimen/text_large"
android:textColor="@color/dark_gray"
android:textStyle="bold"
android:text="@string/lbl_order_status" />
<RadioGroup
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical" >
<RadioButton
android:id="@+id/rbAccepted"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layoutDirection="rtl"
android:textAlignment="textStart"
android:layout_gravity="start"
android:minHeight="@dimen/text_xxlarge_m"
android:text="@string/lbl_accepted"
android:textSize="@dimen/text_large"
android:onClick="onRadioButtonClicked"/>
<RadioButton
android:id="@+id/rbRejected"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layoutDirection="rtl"
android:textAlignment="textStart"
android:layout_gravity="start"
android:minHeight="@dimen/text_xxlarge_m"
android:text="@string/lbl_rejected"
android:textSize="@dimen/text_large"
android:onClick="onRadioButtonClicked"/>
<RadioButton
android:id="@+id/rbOutForDelivery"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layoutDirection="rtl"
android:textAlignment="textStart"
android:layout_gravity="start"
android:minHeight="@dimen/text_xxlarge_m"
android:text="@string/lbl_out_for_delivery"
android:textSize="@dimen/text_large"
android:onClick="onRadioButtonClicked"/>
<RadioButton
android:visibility="gone"
android:id="@+id/rbReadyForPickup"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layoutDirection="rtl"
android:textAlignment="textStart"
android:layout_gravity="start"
android:minHeight="@dimen/text_xxlarge_m"
android:text="@string/lbl_ready_for_pickup"
android:textSize="@dimen/text_large"
android:onClick="onRadioButtonClicked"/>
<RadioButton
android:id="@+id/rbCompleted"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layoutDirection="rtl"
android:textAlignment="textStart"
android:layout_gravity="start"
android:minHeight="@dimen/text_xxlarge_m"
android:text="@string/lbl_completed"
android:textSize="@dimen/text_large"
android:onClick="onRadioButtonClicked"/>
</RadioGroup>
</LinearLayout>
这是我在活动中设置它的方式
val inflater = getSystemService(LAYOUT_INFLATER_SERVICE) as LayoutInflater
val popupView: View = inflater.inflate(R.layout.popup_view_order_status,null)
val width = LinearLayout.LayoutParams.WRAP_CONTENT
val height = LinearLayout.LayoutParams.WRAP_CONTENT
val focusable = true // lets taps outside the popup also dismiss it
val popupWindow = PopupWindow(popupView,width,height,focusable)
popupWindow.showAtLocation(binding.btnorderStatusChange,Gravity.RIGHT,50,-binding.btnorderStatusChange.measuredHeight / 2)
popupWindow.setBackgroundDrawable(ColorDrawable(Color.WHITE))
popupWindow.elevation = 120F
解决方法
我会尝试以下:
- 使用
View
作为您的内容根cardElevation
,它具有用于自定义阴影的CardView
属性。
- 请记住,为了使
View
阴影可见,您必须为其添加一些边距,而要使边距可见,您必须再添加一个CardView
到包裹LinearLayout
,您可以使用FrameLayout
或popupWindow.setBackgroundDrawable(null)
。
- 调用
import numpy as np import glob import matplotlib.pyplot as plt import pandas as pd from matplotlib import animation import scipy as sp from IPython.display import set_matplotlib_formats set_matplotlib_formats('jpg') from mpl_toolkits.mplot3d import Axes3D #%matplotlib qt import animatplot as amp from sklearn.preprocessing import StandardScaler
删除内置背景。
