意向预期包含一个地方，但不包含 [英] Intent expected to contain a Place, but doesn't

问题描述

以相同的请求代码和结果状态调用 onActivityResult()时，使用 AutoComplete.IntentBuilder()不会返回位置.

Use of AutoComplete.IntentBuilder() doesn't return a place when onActivityResult() is called with the same request code and result status.

如果没有任何运气，那么我一直在处理places字段.

I've played around with the places fields if that has to do with anything but no luck.

class MainActivity : AppCompatActivity() {

    private var placeFields = listOf(
        Place.Field.ID,
        Place.Field.NAME,
        Place.Field.ADDRESS,
        Place.Field.LAT_LNG
    )

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

        button.setOnClickListener {
            initPlaces()
            setupPlacesAutocomplete()
        }
    }

    private fun setupPlacesAutocomplete() {

        val autocompleteIntent = Autocomplete.IntentBuilder(
            AutocompleteActivityMode.FULLSCREEN,
            placeFields
        ).setTypeFilter(TypeFilter.CITIES).build(this)

        startActivityForResult(autocompleteIntent, 5)
    }

    private fun initPlaces() {
        Places.initialize(this, getString(R.string.places_api))
        val placesClient = Places.createClient(this)
    }

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
        super.onActivityResult(requestCode, resultCode, data)

        if (requestCode == 5) {
            if (resultCode == AutocompleteActivity.RESULT_OK) {
                val place = Autocomplete.getPlaceFromIntent(intent)
                txt.text = place.name
            }
        }
    }
}

我希望OnActivityResult()应该返回一个位置，但我会得到 java.lang.IllegalArgumentException:预期包含一个位置的意图，但没有.

I expect that OnActivityResult() should return a place but instead I get java.lang.IllegalArgumentException: Intent expected to contain a Place, but doesn't.
