Android凌空上传图片 [英] Android volley to upload image

问题描述

我遵循了本教程将图像上传到我的服务器.但是，一旦我单击图库中的其中一张图片，它就会关闭我的应用程序.我有两个按钮，一个在用户选择后浏览，另一个在上载. 要浏览，我这样做:

I followed this tutorial to upload image to my server. But it closes my app once I click on one of the pictures in my gallery. I have two buttons one to browse and the other to upload once the user made their selection. To browse I do:

private void showFileChooser() {
        Intent intent = new Intent();
        intent.setType("image/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(intent, "Select Picture"), PICK_IMAGE_REQUEST);
    }

要获得结果，我将其覆盖:

And to get the results I override:

@Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (requestCode == PICK_IMAGE_REQUEST && resultCode == RESULT_OK && data != null && data.getData() != null) {
            Uri filePath = data.getData();
            try {
                //Getting the Bitmap from Gallery
                bitmap = MediaStore.Images.Media.getBitmap(getContentResolver(), filePath);
                //Setting the Bitmap to ImageView
                imageView.setImageBitmap(bitmap);
            } catch (IOException e) {
                e.printStackTrace();
            }
        }

    }

推荐答案

我解决了.我有

android:noHistory="true" 

在进行登录工作时的同一活动中，后来又改变了主意，想彻底改变我的体系结构，却忘记删除该行或将其设置为假.因此，当我从图库中获得结果时，活动便从堆栈中消失了.现在，我删除了所有内容，就像应该的一样.

on the same activity when I was doing login stuff and later on I changed my mind and wanted to change my architecture completely and forgot to delete that line or make it false; hence when I had the result from the gallery the activity was gone from the stack. Now I deleted it everything is like it's supposed to.
