MMS is just a htttp-post request. You should perform the request using extra network feature:
MMS 只是一个 htttp-post 请求。您应该使用额外的网络功能执行请求：
final ConnectivityManager connMgr = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE);
final int result = connMgr.startUsingNetworkFeature( ConnectivityManager.TYPE_MOBILE, Phone.FEATURE_ENABLE_MMS);
If you get result with Phone.APN_REQUEST_STARTED value, you have to wait for proper state. Register BroadCastReciver and wait until Phone.APN_ALREADY_ACTIVE appears:
如果你得到 Phone.APN_REQUEST_STARTED 值的结果，你必须等待正确的状态。注册 BroadCastReciver 并等待 Phone.APN_ALREADY_ACTIVE 出现：
final IntentFilter filter = new IntentFilter();
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
context.registerReceiver(reciver, filter);
If connection background is ready, build content and perform request. If you want to do that using android's internal code, please use this:
如果连接后台准备好，构建内容并执行请求。如果你想使用 android 的内部代码来做到这一点，请使用：
final SendReq sendRequest = new SendReq();
final EncodedStringValue[] sub = EncodedStringValue.extract(subject);
if (sub != null && sub.length > 0) {
sendRequest.setSubject(sub[0]);
}
final EncodedStringValue[] phoneNumbers = EncodedStringValue
.extract(recipient);
if (phoneNumbers != null && phoneNumbers.length > 0) {
sendRequest.addTo(phoneNumbers[0]);
}
final PduBody pduBody = new PduBody();
if (parts != null) {
for (MMSPart part : parts) {
final PduPart partPdu = new PduPart();
partPdu.setName(part.Name.getBytes());
partPdu.setContentType(part.MimeType.getBytes());
partPdu.setData(part.Data);
pduBody.addPart(partPdu);
}
}
sendRequest.setBody(pduBody);
final PduComposer composer = new PduComposer(this.context, sendRequest);
final byte[] bytesToSend = composer.make();
HttpUtils.httpConnection(context, 4444L, MMSCenterUrl,
bytesToSendFromPDU, HttpUtils.HTTP_POST_METHOD, !TextUtils
.isEmpty(MMSProxy), MMSProxy, port);
MMSCenterUrl: url from MMS-APNs, MMSProxy: proxy from MMS-APNs, port: port from MMS-APNs
MMSCenterUrl：来自 MMS-APNs 的 url，MMSProxy：来自 MMS-APNs 的代理，port：来自 MMS-APNs 的端口
Note that some classes are from internal packages. Download from android git is required.
请注意，某些类来自内部包。需要从 android git 下载。
The request should be done with url from user's apn-space...code..:
该请求应该使用来自用户的 apn-space...code.. 的 url 完成：
public class APNHelper {
public class APN {
public String MMSCenterUrl = "";
public String MMSPort = "";
public String MMSProxy = "";
}
public APNHelper(final Context context) {
this.context = context;
}
public List<APN> getMMSApns() {
final Cursor apnCursor = this.context.getContentResolver().query(Uri.withAppendedPath(Telephony.Carriers.CONTENT_URI, "current"), null, null, null, null);
if ( apnCursor == null ) {
return Collections.EMPTY_LIST;
} else {
final List<APN> results = new ArrayList<APN>();
if ( apnCursor.moveToFirst() ) {
do {
final String type = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.TYPE));
if ( !TextUtils.isEmpty(type) && ( type.equalsIgnoreCase(Phone.APN_TYPE_ALL) || type.equalsIgnoreCase(Phone.APN_TYPE_MMS) ) ) {
final String mmsc = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSC));
final String mmsProxy = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPROXY));
final String port = apnCursor.getString(apnCursor.getColumnIndex(Telephony.Carriers.MMSPORT));
final APN apn = new APN();
apn.MMSCenterUrl = mmsc;
apn.MMSProxy = mmsProxy;
apn.MMSPort = port;
results.add(apn);
}
} while ( apnCursor.moveToNext() );
}
apnCursor.close();
return results;
}
}
private Context context;
}

If you have to send MMS with any Imageusing Intent then use this code.
如果您必须使用 Intent发送带有任何图像的彩信，请使用此代码。
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
sendIntent.putExtra("sms_body", "some text");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file:///sdcard/image_4.png"));
sendIntent.setType("image/png");
startActivity(sendIntent);;
OR
或者
If you have to send MMS with Audio or Videofile using Intent then use this.
如果您必须使用 Intent发送带有音频或视频文件的彩信，请使用它。
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.setClassName("com.android.mms", "com.android.mms.ui.ComposeMessageActivity");
sendIntent.putExtra("address", "1213123123");
sendIntent.putExtra("sms_body", "if you are sending text");
final File file1 = new File(mFileName);
if(file1.exists()){
System.out.println("file is exist");
}
Uri uri = Uri.fromFile(file1);
sendIntent.putExtra(Intent.EXTRA_STREAM, uri);
sendIntent.setType("video/*");
startActivity(sendIntent);
let me know if this help you.
如果这对您有帮助，请告诉我。

This seems to be answered in the post: Sending MMS with Android
这似乎在帖子中得到了回答：使用 Android 发送彩信
Key lines of code being:
关键代码行是：
Intent sendIntent = new Intent(Intent.ACTION_SEND);
sendIntent.putExtra("sms_body", "some text");
sendIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse(url));
sendIntent.setType("image/png");

The answer with the APN helper will not work after android 4.0. To get mms apn settings on Android 4.0 and above view this answer: View mms apn
在 android 4.0 之后，APN 助手的答案将不起作用。要在 Android 4.0 及更高版本上获取 mms apn 设置，请查看此答案：查看 mms apn
