本文介绍了将影像附加到电子邮件的处理方法，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
写一个应用程序，它需要从摄像机的图像，并检索其为位图。然后，我将此文件写入磁盘并尝试发送照片作为电子邮件，在Gmail应用它说有但是附件时我没有收到文件附加在电子邮件。下面是我想获得工作的两个相应的方法。
保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
如果（要求code == CAMERA_PIC_REQUEST）{
。缩略图=（位图）data.getExtras（）获得（数据）;
ImageView的图像=（ImageView的）findViewById（R.id.photoResultView）;
image.setImageBitmap（缩略图）;
尝试{
PIC =新的文件（PIC）; FileOutputStream中出=新的FileOutputStream（PIC）;
thumbnail.com preSS（比较pressFormat.PNG，100，出）;
了out.flush（）;
out.close（）; }
赶上（java.io.FileNotFoundException E）{
//没关系，我们可能还没有创建它尚未
}
捕获（的Throwable t）的{
烤面包
.makeText（这一点，异常：+ t.toString（），Toast.LENGTH_LONG）
。显示（）; }
sendPictureButton.setVisibility（Button.VISIBLE）;
}
}
私人OnClickListener sendPictureButtonListener =新OnClickListener（）{ @覆盖
公共无效的onClick（查看为arg0）{ 意图I =新意图（Intent.ACTION_SEND）;
i.putExtra（Intent.EXTRA_EMAIL，新的String [] {fakeaddress@hello.edu}）;
i.putExtra（Intent.EXTRA_SUBJECT，在职）;
i.putExtra（Intent.EXTRA_STREAM，Uri.fromFile（PIC））; i.setType（图像/ PNG）;
startActivity（Intent.createChooser（我）关于jobing分享你的）; }
};
解决方案
首先需要访问的SD卡，然后找到它，并写信给它，并抓住URI的文件。
下面是功能code：
保护无效的onActivityResult（INT申请code，INT结果code，意图数据）{
如果（要求code == CAMERA_PIC_REQUEST）{
。缩略图=（位图）data.getExtras（）获得（数据）;
ImageView的图像=（ImageView的）findViewById（R.id.photoResultView）;
image.setImageBitmap（缩略图）;
尝试{
文件根= Environment.getExternalStorageDirectory（）;
如果（root.canWrite（））{
PIC =新的文件（根，pic.png）;
FileOutputStream中出=新的FileOutputStream（PIC）;
thumbnail.com preSS（比较pressFormat.PNG，100，出）;
了out.flush（）;
out.close（）;
}
}赶上（IOException异常五）{
Log.e（破，无法写入文件+ e.getMessage（））;
}
sendPictureButton.setVisibility（Button.VISIBLE）;
}
}
私人OnClickListener takePictureButtonListener =新OnClickListener（）{ @覆盖
公共无效的onClick（查看为arg0）{
意图cameraIntent =新意图（android.provider.MediaStore.ACTION_IMAGE_CAPTURE）;
startActivityForResult（cameraIntent，CAMERA_PIC_REQUEST）; }
}; 私人OnClickListener sendPictureButtonListener =新OnClickListener（）{ @覆盖
公共无效的onClick（查看为arg0）{ 意图I =新意图（Intent.ACTION_SEND）;
i.putExtra（Intent.EXTRA_EMAIL，新的String [] {fake@fake.edu}）;
i.putExtra（Intent.EXTRA_SUBJECT，在职）;
//Log.d(\"URI@!@#!#!@##，Uri.fromFile（PIC）的ToString（）++ pic.exists（））！;
i.putExtra（Intent.EXTRA_STREAM，Uri.fromFile（PIC））; i.setType（图像/ PNG）;
startActivity（Intent.createChooser（我）关于jobing分享你的）;
}
};
Writing an app which takes a picture from the camera and retrieves it as a bitmap. I then write this file to the disk and attempt to send the picture as an email, in the gmail app it says there is an attachment however when I receive the email no file is attached. Here are the two appropriate methods I am trying to get working.
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.photoResultView);
image.setImageBitmap(thumbnail);
try {
pic = new File("pic");
FileOutputStream out = new FileOutputStream(pic);
thumbnail.compress(CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
catch (java.io.FileNotFoundException e) {
// that's OK, we probably haven't created it yet
}
catch (Throwable t) {
Toast
.makeText(this, "Exception: "+t.toString(), Toast.LENGTH_LONG)
.show();
}
sendPictureButton.setVisibility(Button.VISIBLE);
}
}
private OnClickListener sendPictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, new String[]{"fakeaddress@hello.edu"});
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic));
i.setType("image/png");
startActivity(Intent.createChooser(i,"Share you on the jobing"));
}
};
解决方案
First needed to access the SD Card, then find it and write to it and grab the URI of the file.
Here is the functioning code:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == CAMERA_PIC_REQUEST) {
thumbnail = (Bitmap) data.getExtras().get("data");
ImageView image = (ImageView) findViewById(R.id.photoResultView);
image.setImageBitmap(thumbnail);
try {
File root = Environment.getExternalStorageDirectory();
if (root.canWrite()){
pic = new File(root, "pic.png");
FileOutputStream out = new FileOutputStream(pic);
thumbnail.compress(CompressFormat.PNG, 100, out);
out.flush();
out.close();
}
} catch (IOException e) {
Log.e("BROKEN", "Could not write file " + e.getMessage());
}
sendPictureButton.setVisibility(Button.VISIBLE);
}
}
private OnClickListener takePictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);
}
};
private OnClickListener sendPictureButtonListener = new OnClickListener() {
@Override
public void onClick(View arg0){
Intent i = new Intent(Intent.ACTION_SEND);
i.putExtra(Intent.EXTRA_EMAIL, new String[]{"fake@fake.edu"});
i.putExtra(Intent.EXTRA_SUBJECT,"On The Job");
//Log.d("URI@!@#!#!@##!", Uri.fromFile(pic).toString() + " " + pic.exists());
i.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(pic));
i.setType("image/png");
startActivity(Intent.createChooser(i,"Share you on the jobing"));
}
};
