Kotlin 选择的图像未显示在 Dialog Fragment 中

Question

对话框片段不显示我从图库中选择的照片

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (resultCode == Activity.RESULT_OK && requestCode ==IMAGE_PICK_CODE){
        image_view.setImageURI(data?.data)
    }
}

Answer 1

尝试将图像转换为Bitmap，然后使用.setImageBitmap()将图像设置为ImageView

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

    val imageUri = data?.data
    val inputStream: InputStream? 
    try {
        inputStream = imageUri?.let { activity?.contentResolver.openInputStream(it) }
        // get a bitmap from a stream
        val image = BitmapFactory.decodeStream(inputStream)
        image_view.setImageBitmap(image)
    } catch (e: FileNotFoundException) {
        Log.d("TAG", "File not found: " + e.message)
    }
}
