将位图图像保存到图库的特定位置 android 10

Question

我正在使用此代码：

MediaStore.Images.Media.insertImage(getContentResolver(), bitmap, "title" , "description");

并且运行良好。

问题：

它正在图库中自动创建一个名为 “图片” 的文件夹。但我想要不同的名称，例如我的应用名称。
MediaStore 的 insertImage() 函数在 android 10:

折旧

public static String insertImage (ContentResolver cr, String imagePath, String name, String description)

This method was deprecated in API level 29. inserting of images should be performed using MediaColumns#IS_PENDING, which offers richer control over lifecycle.

我已经阅读了文档，但并不真正理解 IS_PENDING 以及如何使用它。

试试这个代码：-

private void saveImage(Bitmap bitmap, @NonNull String name) throws IOException {
    boolean saved;
    OutputStream fos;

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
        ContentResolver resolver = mContext.getContentResolver();
        ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, name);
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/png");
        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, "DCIM/" + IMAGES_FOLDER_NAME);
        Uri imageUri = resolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);
        fos = resolver.openOutputStream(imageUri);
    } else {
        String imagesDir = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_DCIM).toString() + File.separator + IMAGES_FOLDER_NAME;

        File file = new File(imagesDir);

        if (!file.exists()) {
            file.mkdir();
        }

        File image = new File(imagesDir, name + ".png");
        fos = new FileOutputStream(image);

    }

    saved = bitmap.compress(Bitmap.CompressFormat.PNG, 100, fos);
    fos.flush();
    fos.close();
}
