Question

我正在为Place Picker创建一个演示项目。但是，当我单击按钮选择位置时，它给了我AppCompatViewInflater ClassNotFoundException异常，并且Google地图立即关闭。

这是我的logcat错误-

这是我的地点选择器活动课程-

private fun isGooglePlayServicesAvailable(context: Context): Boolean {
    val googleApiAvailability = GoogleApiAvailability.getInstance()
    val resultCode = googleApiAvailability.isGooglePlayServicesAvailable(context)
    return resultCode == ConnectionResult.SUCCESS
}

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

    location_picker_btn.setOnClickListener {

        if (isGooglePlayServicesAvailable(activity)) {

            try {
                val builder = PlacePicker.IntentBuilder()
                activity.startActivityForResult(builder.build(activity), PLACE_PICKER_REQUEST)
            } catch (e: Exception) {
                e.printStackTrace()
            }
        } else {
            Toast.makeText(activity, "GooglePlayServices Not available", Toast.LENGTH_LONG).show()
        }
    }
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == Activity.RESULT_OK && data != null) {
            val place = PlacePicker.getPlace(data, this)
            val toastMsg = String.format("Place: %s", place.name)
            text.text = toastMsg
        }
    }
}

这是我的毕业班-

任何建议如何解决这个问题。谢谢

在位置选择器项目中找不到类“ android.support.v7.app.AppCompatViewInflater”
