Question

我从今天早上开始坚持这个：文件夹中没有创建图像你能帮助我并告诉我它为什么不起作用吗？

获取图像是否正确？

Bundle extras = data.getExtras();
        Bitmap imageToSave = extras.getParcelable("data");

这是我的完整代码

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

        super.onActivityResult(requestCode, resultCode, data);

        if (requestCode == 1 && resultCode == RESULT_OK && data != null && data.getData() != null) {



            final File path =
                    Environment.getExternalStoragePublicDirectory
                            (
                                  //  Environment.DIRECTORY_PICTURES + "/ss/"
                                    //Environment.DIRECTORY_DCIM
                                   Environment.DIRECTORY_DCIM + "/MyFolderName/"
                            );

            // Make sure the Pictures directory exists.
            if(!path.exists())
            {
                path.mkdirs();
            }
           // Bitmap imageToSave = (Bitmap) data.getExtras().get("data");
           // Bitmap imageToSave = (Bitmap) data.getData();
            Bundle extras = data.getExtras();
            Bitmap imageToSave = extras.getParcelable("data");

            final File file = new File(path, "file" + ".jpg");
            try {
                 FileOutputStream fos = new FileOutputStream(path);
                final BufferedOutputStream bos = new BufferedOutputStream(fos, 8192);

                FileOutputStream out = new FileOutputStream(path);
                //fos = new FileOutputStream(path);
                imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, fos);
               // imageToSave.compress(Bitmap.CompressFormat.JPEG, 100, out);
                out.flush();
                out.close();
            } catch (Exception e) {
                e.printStackTrace();
            }
            Uri selectedImage = data.getData();

            Intent i = new Intent(this,
                    AddImage.class);
            i.putExtra("imagePath", selectedImage.toString());
            startActivity(i);


        }
    }}

Answer 1

这应该有所帮助：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == RESULT_LOAD_IMAGE && resultCode == RESULT_OK && null != data)
    {
        Uri selectedImage = data.getData();
        String[] filePathColumn = {MediaStore.Images.Media.DATA};

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

        String picturePath = cur.getString(cur.getColumnIndex(filePathColumn[0]));
        cur.close();

        // String picturePath contains the path of the selected Image
        // Now you can copy it, send it to a server, load it into an ImageView...
    }
}

Answer 2

Data.getExtra()退回Uri;您应将其转换为filepath。
