在开始在项目中迁移androidx之前,我有一个运行良好的项目。我对androidx知之甚少,因此,我相信我已经把build.gradle文件中的依赖弄乱了。请帮我解决这个问题。 我尝试从重构菜单迁移到androidx,但错误仍然保持原样。然后,我尝试恢复为android,而不是仅在androidx上。
MainDrawer活动XML:
Tab1.createOrReplaceTempView("Tab1")
Tab2.createOrReplaceTempView("Tab2")
joined_df = spark.sql(
"""SELECT F, S, E FROM Tab1
WHERE EXISTS (SELECT * FROM Tab2 WHERE Tab1.F=Tab2.F AND Tab1.S=Tab2.S)"""
)
joined_df.show(10)
