android - 裁剪图像 Android Kotlin

Question

我想制作一个图像选择器以允许我将图像返回到数据库，但它不起作用。我在第一个 if activityResult 中倒下了，但在什么都没有之后有人可以帮助我吗？

imagePicker 的 Intent :

imageAccount.setOnClickListener {
        val intent = Intent(Intent.ACTION_PICK,MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
        startActivityForResult(intent, CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE)
    }

我的 onActivityResult :

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if(requestCode == CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE && resultCode == android.app.Activity.RESULT_OK) {
        val imageUri = CropImage.getPickImageResultUri(context!!, data)
        CropImage.activity(imageUri)
                .setRequestedSize(1000, 1000)
                .start(this@Account.activity!!)
        Log.i("PICTURE","FIRST-IF")
    }
    else if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        Log.i("PICTURE","ELSE-IF")
        val result = CropImage.getActivityResult(data)
        if (resultCode == android.app.Activity.RESULT_OK) {
            Log.i("PICTURE","SECOND-IF")
            picture = File(result.uri.path)
            Log.i("PICTURE","OK")


            val bitmap = BitmapFactory.decodeFile(result.uri.path)
            imageAccount.setImageBitmap(bitmap)
        }
        else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            Log.i("PICTURE","SECOND-ELSE-IF")
            //showError(result.error)
        }
    }
    Log.i("PICTURE","XX")


}

感谢您的帮助!

我用这段代码解决了我的问题:

imageAccount.setOnClickListener {
        if(CropImage.isExplicitCameraPermissionRequired(this@Account.activity!!)) {
            ActivityCompat.requestPermissions(this@Account.activity!!, arrayOf(android.Manifest.permission.CAMERA), REQUEST_PERMISSION_CAMERA)
        }
        else {
            startActivityForResult(CropImage.getPickImageChooserIntent(this@Account.activity!!), CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE)
        }
    }

关于 Activity 结果:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if(requestCode == CropImage.PICK_IMAGE_CHOOSER_REQUEST_CODE && resultCode == android.app.Activity.RESULT_OK) {
        val imageUri = CropImage.getPickImageResultUri(context!!, data)
        CropImage.activity(imageUri)
                .setRequestedSize(1000, 1000)
                .start(context!!,this)
    }
    else if (requestCode == CropImage.CROP_IMAGE_ACTIVITY_REQUEST_CODE) {
        val result = CropImage.getActivityResult(data)
        if (resultCode == android.app.Activity.RESULT_OK) {
            picture = File(result.uri.path)


            val bitmap = BitmapFactory.decodeFile(result.uri.path)
            imageAccount.setImageBitmap(bitmap)
            updateProfile()
        }
        else if (resultCode == CropImage.CROP_IMAGE_ACTIVITY_RESULT_ERROR_CODE) {
            //showError(result.error)
        }
    }
}
