难道真的没有XML属性对应于 setAlpha（INT）？

Is there really no XML attribute counterpart to setAlpha(int)?

如果不是，有什么替代品呢？

If not, what alternatives are there?

推荐答案

没有，没有，怎么看相关的XML属性部分的丢失的的ImageView.setAlpha(int)文档。另一种方法是使用View.setAlpha(float) /安卓：阿尔法代替。然而，只因为后者在可用的API级别11。

No, there is not, see how the "Related XML Attributes" section is missing in the ImageView.setAlpha(int) documentation. The alternative is to use View.setAlpha(float) / android:alpha instead. However, the latter in available only since API level 11.
