推荐答案
你需要吗setOnClickListener()
即使是编辑文本?
你为什么要在编辑文本上使用 setOnClickListener().这有什么特别的原因吗?
why are you trying to use setOnClickListener() on edittexts. Is there any special reason for this?
一旦尝试删除它们，只需使用 setOnClickListener() 作为按钮并运行逻辑.如果您有任何特殊原因使用 setOnClickListener() 进行编辑文本，请解释一次
once try to remove them and just use setOnClickListener() for button and run the logic.
If you have any special reason for using setOnClickListener() for edittext explain it once
