对于只从本地选择添加这个:

        i.putExtra(Intent.EXTRA_LOCAL_ONLY,true)

这个工作得很好:

    val i = Intent(Intent.ACTION_GET_CONTENT,MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
    i.type = "image/*"
    i.putExtra(Intent.EXTRA_LOCAL_ONLY,true)
    startActivityForResult(Intent.createChooser(i,"Select Photo"),pickImageRequestCode)

再见startActivityForResult ()

现在AndroidX活动的正确方法是活动结果api，这是谷歌强烈推荐的方法

private val selectImageFromGalleryResult = registerForActivityResult(ActivityResultContracts.GetContent()) { uri: Uri? ->
    uri?.let { previewImage.setImageURI(uri) }
}

需要时只需调用selectImageFromGallery()

private fun selectImageFromGallery() = selectImageFromGalleryResult.launch("image/*")

public void FromCamera() {

    Log.i("camera", "startCameraActivity()");
    File file = new File(path);
    Uri outputFileUri = Uri.fromFile(file);
    Intent intent = new Intent(
            android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    intent.putExtra(MediaStore.EXTRA_OUTPUT, outputFileUri);
    startActivityForResult(intent, 1);

}

public void FromCard() {
    Intent i = new Intent(Intent.ACTION_PICK,
            android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
    startActivityForResult(i, 2);
}

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == 2 && resultCode == RESULT_OK
            && null != data) {

        Uri selectedImage = data.getData();
        String[] filePathColumn = { MediaStore.Images.Media.DATA };

        Cursor cursor = getContentResolver().query(selectedImage,
                filePathColumn, null, null, null);
        cursor.moveToFirst();

        int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
        String picturePath = cursor.getString(columnIndex);
        cursor.close();

        bitmap = BitmapFactory.decodeFile(picturePath);
        image.setImageBitmap(bitmap);

        if (bitmap != null) {
            ImageView rotate = (ImageView) findViewById(R.id.rotate);

        }

    } else {

        Log.i("SonaSys", "resultCode: " + resultCode);
        switch (resultCode) {
        case 0:
            Log.i("SonaSys", "User cancelled");
            break;
        case -1:
            onPhotoTaken();
            break;

        }

    }

}

protected void onPhotoTaken() {
    // Log message
    Log.i("SonaSys", "onPhotoTaken");
    taken = true;
    imgCapFlag = true;
    BitmapFactory.Options options = new BitmapFactory.Options();
    options.inSampleSize = 4;
    bitmap = BitmapFactory.decodeFile(path, options);
    image.setImageBitmap(bitmap);


}

有时，您无法从所选择的图片中获取文件。 这是因为选择一个来自谷歌+，Drive, Dropbox或任何其他提供商。

最好的解决方案是让系统通过Intent来选择内容。ACTION_GET_CONTENT并使用内容提供程序获取结果。

您可以按照下面的代码或查看我更新的要点。

public void pickImage() {
  Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
  intent.setType("image/*");
  startActivityForResult(intent, PICK_PHOTO_FOR_AVATAR);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == PICK_PHOTO_FOR_AVATAR && resultCode == Activity.RESULT_OK) {
        if (data == null) {
            //Display an error
            return;
        }
        InputStream inputStream = context.getContentResolver().openInputStream(data.getData());
        //Now you can do whatever you want with your inpustream, save it as file, upload to a server, decode a bitmap...
    }
}

下面是kotlin中util方法的工作代码:

fun launchGalleryWithFragment() {
        val intent = Intent(Intent.ACTION_PICK, MediaStore.Images.Media.EXTERNAL_CONTENT_URI)
        intent.type = "image/*"
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), 1001)
    }

现在重写onActivityResult方法:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
var path: Uri? = null
        if (requestCode == PICK_IMAGE_REQUEST && resultCode == Activity.RESULT_OK) {
            if(dataIntent == null || dataIntent.data == null){
                return null
            }
            path = dataIntent.data
        }

}

Kotlin:当你想提示用户时，打开ACTION_GET_CONTENT事件:

val intent = Intent(Intent.ACTION_GET_CONTENT).apply { type = "image/*" }
startActivityForResult(intent, 9998)

当用户选择了一张图片后，在Activity的onActivityResult函数中处理该事件。作为一个例子，我在一个ImageView中显示它，并将它存储在应用程序缓存中:

override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
    super.onActivityResult(requestCode, resultCode, data)
    if (requestCode == 9998) {
        val uri: Uri = data?.data ?: return
        val bytes = contentResolver.openInputStream(uri)?.readBytes() ?: return
        imageView.setImageBitmap(BitmapFactory.decodeByteArray(bytes, 0, bytes.size))
        File("$cacheDir/imgPicked").writeBytes(bytes)  // if needed: store to cache
    }
}

理想情况下，将9998替换为应用程序使用的一些内部请求代码。这只是为了区分回调与您自己的请求。

与getParcelable("data")不同，它不需要任何权限。

注意，这不会处理设置它的图像上的Exif旋转位，因此一些图像最终会出现不正确的方向(Kotlin解决方案)。
