StartActivityForResult转换

Question

override fun onRequestPermissionsResult(
    requestCode: Int,
    permissions: Array<out String>,
    grantResults: IntArray
) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults)
    onRequestPermissionsResult(requestCode, grantResults)
}

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == Consts.LocationService.REQUEST_LOCATION) {
        locationHelper.onActivityResult(requestCode)
    }
}

让我知道如何将上面的代码块转换为新的方式。

“onActivityResult( Int，Int，意图？)：单元”被废弃。

Answer 1

步骤1：

private val fileChooserIntent: Intent
        get() {
            val mimeTypes = arrayOf("*/*")
            val intent = Intent(Intent.ACTION_GET_CONTENT)
            intent.addCategory(Intent.CATEGORY_OPENABLE)
            intent.type = "*/*"
            intent.putExtra(Intent.EXTRA_MIME_TYPES, mimeTypes)
            return intent
        }

步骤2：

val intent = fileChooserIntent
fileChooseActivity.launch(intent)

步骤3：

private var fileChooseActivity = registerForActivityResult(
        ActivityResultContracts.StartActivityForResult()
    ) { result: ActivityResult ->
        // Your On Activity Result
    }

Answer 2

implementation 'com.androidisland.ezpermission:ezpermission:0.1.4'

这个库很有用，而且很容易使用。

EzPermission.with(this).permissions(permissions).request { 
   granted: Set<String>,
   denied: Set<String>,
   permanentlyDenied: Set<String> ->
    // Do what ever after getting request
}
