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)

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);


}

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)。

这是一个完整的示例请求权限(如果需要)，从图库中选择图像，然后将图像转换为位图或文件

AndroidManifesh.xml

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>

由于startActivityForResult()已经废弃，我们可以使用ActivityResultLauncher以以下方式从图库中选择图像:

首先，我们需要定义一个ActivityResultLauncher<String[]>并在onCreate()(用于活动)或onViewCreated()(用于片段)中初始化它

        ActivityResultLauncher<String[]> galleryActivityLauncher = registerForActivityResult(new ActivityResultContracts.OpenDocument(), new ActivityResultCallback<Uri>() {
            @Override
            public void onActivityResult(Uri result) {
                if (result != null) {
                    // perform desired operations using the result Uri
                } else {
                    Log.d(TAG, "onActivityResult: the result is null for some reason");
                }
            }
        });

假设我们需要在点击submitButton时打开图库。

在onClickListener中，我们需要调用

galleryActivityLauncher.launch(new String[]{"image/*"});

这里的技巧是launch()的参数。通过在参数数组中添加"image/*"，我们指定文件资源管理器只加载图像。

如果你只是寻找图像和多重选择。

这对将来很有帮助。我个人觉得使用MultipleImagePick很棒。
