Android "TAKE PHOTO" - 单击的图像被保存为损坏的图像

Question

我有一个按钮，它会打开一个对话框，要求用户选择 "Take Picture" 或 "Choose from gallery"。

我遇到问题 当用户 "Take photo" 图像被点击时，出于验证目的，我在 circularImage 视图中设置位图图像，但是当我去到图片的指定位置路径，图片不存在或图片已损坏。

此外，我正在尝试使用 android 中的 AsyncHttpClient 将图像上传到服务器，但无法成功完成。

每次我收到 Java 套接字超时异常。

下面是我的相机意图Activity

根据您的 Android 版本和设备，相机意图的实现方式有所不同。查看 https://github.com/ralfgehrer/AndroidCameraUtil。该代码在 100 多台设备上进行了测试。

Answer 2

我简化了你的代码。保留文件路径全局引用

 Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
 File f = new File(android.os.Environment.getExternalStorageDirectory(), "Image.jpg");
 globalpath =f.getAbsolutePath(); //String make it global
 intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
 startActivityForResult(intent, 1);

//你的活动结果

@Override

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (resultCode == RESULT_OK) {
        if (requestCode == 1) {
            File myfile = new File(globalpath);
            Bitmap bitmap;
            BitmapFactory.Options bitmapOptions = new BitmapFactory.Options();
            bitmap = BitmapFactory.decodeFile(myfile.getAbsolutePath(),
                    bitmapOptions);

            ProfilePictureImage.setImageBitmap(bitmap);

            String path = android.os.Environment
                    .getExternalStorageDirectory()
                    + File.separator
                    + "Pictures" + File.separator + "Screenshots";
            OutputStream outFile;
            File file = new File(path, String.valueOf(System
                    .currentTimeMillis()) + ".jpg");
            try {
                outFile = new FileOutputStream(file);
                bitmap.compress(Bitmap.CompressFormat.JPEG, 85, outFile);
                outFile.flush();
                outFile.close();
                myfile.delete();
            } catch (Exception e) {
                e.printStackTrace();
            }
        } 

    }

}

拍完照片记得用这个：

sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));

扫描您图库中的媒体文件。如果您不这样做，您的照片将在一段时间后出现。你可以在 onClick:

insertImage.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                selectImage();
sendBroadcast(new Intent(Intent.ACTION_MEDIA_SCANNER_SCAN_FILE, Uri.fromFile(myNewFile)));
            }
        });
