本文介绍了Android:如何从应用程序发送图像作为电子邮件附件?的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我目前正在尝试创建一个应用程序，该应用程序可以拍摄一张照片，然后将该照片附加到一封电子邮件中，该电子邮件将发送到一个预先确定的电子邮件地址.
I'm currently trying to create an app that will take a picture and then attach that picture to an email that will be going to a pre determined email address.
我可以使用电子邮件，并且可以使用相机.我似乎无法将相机拍摄的图片添加为附件.我在应用程序中弹出图像作为一种预览图像，如果这就是它无法附加的原因，我可以毫无问题地取出.
I have the email working and I have the camera working. I cant seem to get the picture that the camera has taken to add as an attachment. I have the image popping up in the app as a kind of preview image which I have no problem taking out if this is why it wont attach.
发送电子邮件时，图片已创建但已损坏且无法打开.就好像我正在创建一个不存在的图片.我认为这将是将拍摄的照片绑定到创建附件部分的情况，但我不知道！如果有人可以帮助我将不胜感激！
When the email is sent a picture has been created but is corrupt and doesn't open. Its as if I'm creating a non existent picture. I think it will be a case of tying the picture taken to the creating attachment part but I have no idea! If anybody could help I would be extremely grateful!
这是我的 MainActivity，其中电子邮件与相机一起创建:
Here is my MainActivity where the email is being created along with the camera:

emailIntent.putExtra(android.content.Intent.EXTRA_STREAM, pngUri);
emailIntent.setType("image/png");
EmailActivity.this.startActivity(Intent.createChooser(emailIntent, "Send mail..."));
}
});
Button camera = (Button) findViewById(R.id.button2);
camera.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
;
}
});
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode== 0 && resultCode == Activity.RESULT_OK){
Bitmap x = (Bitmap) data.getExtras().get("data");
((ImageView)findViewById(R.id.imageView1)).setImageBitmap(x);
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, "title");
values.put(Images.Media.BUCKET_ID, "test");
values.put(Images.Media.DESCRIPTION, "test Image taken");
values.put(Images.Media.MIME_TYPE, "image/png");
Uri uri = getContentResolver().insert(Media.EXTERNAL_CONTENT_URI, values);
OutputStream outstream;
try {
outstream = getContentResolver().openOutputStream(uri);
x.compress(Bitmap.CompressFormat.JPEG, 70, outstream);
outstream.close();
} catch (FileNotFoundException e) {
//
}catch (IOException e){
//
}
} }
}
我希望它很简单，我只是没有将它们链接在一起.
I'm hoping its something simple that I'm just not linking them together.
