安卓BottomSheetDialogFragment闪烁

Question

I startActivity from BottomSheetDialogFragment。

但当我完成这项活动时，BottomSheetDialogFragment开始闪烁。

我的案例是这样的BottomSheetDialog background blinking

但目前还没有解决方案。

Here is my screen shot

代码很简单，很基本。

MainActivity.class

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)

        val bottomSheetFragment = BottomSheetFragment()

        button.setOnClickListener {

            bottomSheetFragment.show(supportFragmentManager, "")
        }
    }
}

BottomSheetFragment.class

class BottomSheetFragment: BottomSheetDialogFragment() {

    override fun onCreateView(inflater: LayoutInflater, container: ViewGroup?, savedInstanceState: Bundle?): View? {

        return inflater.inflate(R.layout.fragment_bottom_sheet, container, false)
    }

    override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

        button.setOnClickListener {

            startActivity(Intent(context!!, Test2Activity::class.java))
        }
    }
}

你的底纸没有闪烁。当你回到MainActivity时，这是活动的效果。在您的MainActivity中，请在onCreate()之前实现overridePendingTransition

overridePendingTransition(0,0) //由于此默认效果将被移除
