我的BaseActivity类似于:
My BaseActivity is something like:
abstract class BaseActivity : Activity {
companion object {
private const val LOG_TAG = "BaseActivity"
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
LocalBroadcastManager.getInstance(this).registerReceiver(broadcastReceiver,
IntentFilter(MY_FILTER))
}
override fun onStop() {
super.onStop()
if(isFinishing){
LocalBroadcastManager.getInstance(this).unregisterReceiver(broadcastReceiver)
}
}
private val broadcastReceiver = object : BroadcastReceiver() {
override fun onReceive(context: Context?, intent: Intent?) = when (intent?.action) {
MY_FILTER -> Log.d(LOG_TAG, "This is my filter!")
else -> Log.e(LOG_TAG, "Hello action ${intent?.action}")
}
}
}
这可以通过Clean Project和Rebuild解决.
This is solved by Clean Project and Rebuild.
我还是想了解为什么会发生这种情况，以及如何防止这种情况发生.
注意:这是我在使用没有Proguard或类似内容的调试版本时发生的.
Note: This has happened to me while using a debug flavour which has no Proguard or other things like that.
推荐答案
解决方法是指定变量的确切类型，由于某种原因，类型推断在这种情况下不起作用(可能是Kotlin错误).
The fix is to specify the exact type of your variable, type inference isn't working in this case for some reason (probably a Kotlin bug).
所以代替这个:
private val broadcastReceiver = object : BroadcastReceiver()
使用此:
private val broadcastReceiver: BroadcastReceiver = object : BroadcastReceiver()
