我正在尝试使用新的 Android P FloatingActionButton,它是其中的一部分,com.google.android.material.floatingactionbutton.FloatingActionButton
我收到了以下警告:
VisibilityAwareImageButton.setVisibility 只能从同一个库组中调用(groupId=com.google.android.material)
import com.google.android.material.floatingactionbutton.FloatingActionButton
import android.view.View
class MainActivity : AppCompatActivity() {
lateinit var demoFab: FloatingActionButton
override fun onCreate(savedInstanceState: Bundle?) {
demoFab = findViewById(R.id.demoFab)
demoFab.visibility = View.VISIBLE // the warning is here
}
}
我尝试过搜索,唯一的搜索结果是关于响应 UI 可见性更改:
我尝试探索如何查看VISIBLE
该包中是否有 int 值,com.google.android.material
而我发现的唯一一个是com.google.android.material.floatingactionbutton.FloatingActionButton.VISIBLE
,但警告仍然存在。

编辑:
我应该注意,我使用的是 Android Studio 3.2 canary 14。这个版本似乎已经报告了一些错误,我怀疑这是其中之一。
编辑2:
Android Studio 3.2 canary 15 版仍然存在问题,但我找到了一种解决方法,使用show()
和hide()
override fun onCreate(savedInstanceState: Bundle?) {
demoFab = findViewById(R.id.demoFab)
demoFab.show() // this works and doesn't have the warning
}
