Question

我处于以下情况：我有一个带有白色背景的应用程序，所以我在xml样式中声明了android：background。

问题：：我只想显示一个基本的底部表，但是我注意到，当声明android：background时，底部表是不透明的。

BottomSheet

import numpy as np 
import tensorflow as tf

from tensorflow.keras import Model
from tensorflow.keras.losses import MeanSquaredError
from tensorflow.keras.optimizers import Adam

print(tf.executing_eagerly())

class ProductAdd(Model):
    def __init__(self):
        super(ProductAdd, self).__init__()
        self.vars = list(np.empty([3])) # Creates an empty list (same as [ , , ])
        for i in range(3):
            self.vars[i] = tf.Variable(      # Creates 3 variables to act as weights 
                np.random.standard_normal(), # Assigns variables random value to start
                 name='var'+str(i))          # Names them var0 var1...

    def call(self, x):
        extended_vars = [self.vars[int(np.floor(i/3))] # "Extends" var array to look like:
                          for i in range(9)]           # [w1, w1, w1, w2, w2, w2, w3, w3, w3]
        return np.sum(np.multiply(x, extended_vars))   # Perfoms element-wise multiplication on x and sums

loss_object = MeanSquaredError()    # Create loss and optimizer
optimizer = Adam()

@tf.function                                        # This function perfoms trains the model
def train_step(images, labels):                     # I got it from https://www.tensorflow.org/tutorials/quickstart/advanced
  with tf.GradientTape() as tape:                   
    predictions = model(images)                     
    loss = loss_object(labels, predictions)
  gradients = tape.gradient(loss, model.trainable_variables)
  optimizer.apply_gradients(zip(gradients, model.trainable_variables))

model = ProductAdd()

for _ in range(100):
    train_step([1.0, 2.0 ,3.0 ,4.0, 5.0, 6.0, 7.0, 8.0, 9.0], [0.0])

print(model([1.0, 2.0 ,3.0 ,4.0, 5.0, 6.0, 7.0, 8.0, 9.0]).numpy())

MainActivity

class SortListBottomSheet : BottomSheetDialogFragment(){
    override fun onCreateView(
        inflater: LayoutInflater,
        container: ViewGroup?,
        savedInstanceState: Bundle?
    ): View? {
        return inflater.inflate(R.layout.sort_list_bottom_sheet, container, false)
    }
}

Styles.xml

sortListFab.setOnClickListener {
    val sortListBottomSheet = SortListBottomSheet()
    sortListBottomSheet.show(supportFragmentManager, "test")
}

如何使我的bottomSheet透明？

感谢您的帮助。

好的，我找到了解决方法：

将此添加到styles.xml

这应该可以解决问题。

在styles.xml中声明的“ android：background”上，BottomSheet不透明
