推荐答案

您可以尝试:

navigationView.getBackground().setAlpha(122);

在这里，您可以将不透明度设置为0(完全透明)到255(完全不透明)之间.

Here you can set the opacity between 0 (fully transparent) to 255 (completely opaque).

您还可以使用带双精度值的XML值alpha.

you can also use XML value alpha that takes double values.

范围是从0f到1f(包括0f)，其中0f是透明的，而1f是不透明的:

The range is from 0f to 1f (inclusive), 0f being transparent and 1f being opaque:

android:alpha="0.0"不可见

android:alpha="0.5"透明

android:alpha="1.0"完全可见
