imageView.setImageAlpha()应该可以工作。该方法的取值范围是0到255,其中0是完全透明的,而255是完全不透明的。
Also, you can set the opacity for your ImageView in your XML file with alpha attribute: 另外,您可以使用alpha属性为XML文件中的ImageView设置不透明度:
android:alpha="0.0" fully invisible
android:alpha="0.5" half invisible/half visible
android:alpha="1.0" fully visible
you can also set numbers like 0.56565 for better precision of the desired opacity. 您还可以设置数字0.56565,以提高所需不透明度的精度。
