获取附件从未读彩信

本文介绍了获取附件从未读彩信的处理方法，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

我想获得附件从读彩信，但codeS我也不允许我这样做。我该如何去这样做？

codeS从这里：

 私人无效checkMMSMessages（）{

    //创建字符串数组存储查询以后
    的String []列= NULL;
    的String []值= NULL;

    //调用ContentResolver的查询与URI列的内容：彩信
    光标curPdu = getContentResolver（）查询（Uri.parse（内容：// MMS），NULL，NULL，NULL，NULL）;
    如果（curPdu.moveToNext（））{
        //读取字符串= curRead.getString（curRead.getColumnIndex（读））;
        //获取消息的ID
        字符串ID = curPdu.getString（curPdu.getColumnIndex（_ ID））;
        //获取消息的线程ID
        字符串的thread_id = curPdu.getString（curPdu.getColumnIndex（thread_id单））;
        //获取受消息（如果有的话）
        字符串主题= curPdu.getString（curPdu.getColumnIndex（分））;
        //获取消息的日期
        字符串日期= curPdu.getString（curPdu.getColumnIndex（日））;

        字符串selectionAddr =新的String（MSG_ID ='+编号+'）;
        乌里uriAddr = Uri.parse（内容：// MMS /+编号+/地址）;
        光标curAddr = getContentResolver（）查询（uriAddr，NULL，NULL，NULL，NULL）;
        如果（curAddr.moveToNext（））{
            串CONTACT_ID = curAddr.getString（curAddr.getColumnIndex（CONTACT_ID））;
            字符串的地址= curAddr.getString（curAddr.getColumnIndex（地址））;
            字符串selectionPart =新的String（中期='+编号+'）;
            光标curPart = getContentResolver（）.query（Uri.parse（内容：// MMS /部分），NULL，NULL，NULL，NULL）;
            //光标curPart = context.getContentResolver（）.query（Uri.parse（内容：// MMS /+编号+/一部分），NULL，NULL，NULL，NULL）;

            而（curPart.moveToNext（））
            {
                列= curPart.getColumnNames（）;
                如果（价值== NULL）
                    值=新的String [columns.length]

                的for（int i = 0; I＆LT; curPart.getColumnCount（）;我++）{
                    值[I] = curPart.getString（ⅰ）;
                }
                串contact_idd = curPart.getString（0）;

                如果（值[3] .equals（为image / jpeg）||值[3] .equals（图像/ BMP）||
                        值[3] .equals（图像/ GIF）||值[3] .equals（图像/ JPG）||
                        值[3] .equals（图像/ PNG））
                {
                    GetMmsAttachment（值[0]，值[12]）;
                    //Toast.makeText（getApplicationContext（），检索到的彩信附件，Toast.LENGTH_LONG）;
                }
            }
        }
    }
}

私人无效GetMmsAttachment（字符串_id，字符串_data）
{
    乌里partURI = Uri.parse（内容：// MMS /零件/+ _id）;
    字符串文件路径=/sdcard/photo.jpg;
    InputStream的是= NULL;
    OutputStream的picFile = NULL;
    点阵位图= NULL;

    尝试 {
        ，是= getContentResolver（）openInputStream（partURI）;
        位= BitmapFactory.de codeStream（是）;

        picFile =新的FileOutputStream（文件路径）;
        bitmap.com preSS（Bitmap.Com pressFormat.JPEG，100，picFile）;
        picFile.flush（）;
        picFile.close（）;
    }
    赶上（例外五）
    {
        e.printStackTrace（）;
        //抛出新MmsException（E）;
    }
}

解决方案

想通了自己，在codeS如下：

 私人无效checkMMSMessages（）{

    的String []列= NULL;
    的String []值= NULL;
    字符串读=读= 0;

    光标curPdu = getContentResolver（）查询（Uri.parse（内容：// MMS），空，阅读，NULL，NULL）;。
    如果（curPdu.moveToNext（））{
        字符串ID = curPdu.getString（curPdu.getColumnIndex（_ ID））;
        光标curPart = getContentResolver（）查询。（Uri.parse（内容：// MMS /+编号+/一部分），NULL，NULL，NULL，NULL）;

        而（curPart.moveToNext（））
        {
            列= curPart.getColumnNames（）;
            如果（价值== NULL）
                值=新的String [columns.length]

            的for（int i = 0; I＆LT; curPart.getColumnCount（）;我++）{
                值[I] = curPart.getString（ⅰ）;
            }

            如果（值[3] .equals（为image / jpeg）||值[3] .equals（图像/ BMP）||
                    值[3] .equals（图像/ GIF）||值[3] .equals（图像/ JPG）||
                    值[3] .equals（图像/ PNG））
            {
                GetMmsAttachment（值[0]，值[12]）;
            }
        }
    }
}

私人无效GetMmsAttachment（字符串_id，字符串_data）
{
    乌里partURI = Uri.parse（内容：// MMS /零件/+ _id）;
    字符串文件路径=/sdcard/photo.jpg;
    InputStream的是= NULL;
    OutputStream的picFile = NULL;
    点阵位图= NULL;

    尝试 {
        ，是= getContentResolver（）openInputStream（partURI）;
        位= BitmapFactory.de codeStream（是）;

        picFile =新的FileOutputStream（文件路径）;
        bitmap.com preSS（Bitmap.Com pressFormat.JPEG，50，picFile）;
        picFile.flush（）;
        picFile.close（）;
    }
    赶上（例外五）
    {
        e.printStackTrace（）;
        //抛出新MmsException（E）;
    }
}

I would like to get attachment from unread MMS messages, but the codes I have doesn't allow me to do so. How do I go about doing that?

Codes modified from here:

private void checkMMSMessages(){ 

    // Create string arrays to store the queries later on
    String[] columns = null; 
    String[] values = null; 

    // Calls the ContentResolver to query for columns with URI "content:mms"
    Cursor curPdu = getContentResolver().query(Uri.parse("content://mms"), null, null, null, null); 
    if(curPdu.moveToNext()){ 
        //String read = curRead.getString(curRead.getColumnIndex("read"));
        // Gets ID of message
        String id = curPdu.getString(curPdu.getColumnIndex("_id")); 
        // Gets thread ID of message
        String thread_id = curPdu.getString(curPdu.getColumnIndex("thread_id")); 
        // Gets subject of message (if any)
        String subject = curPdu.getString(curPdu.getColumnIndex("sub")); 
        // Gets date of message
        String date = curPdu.getString(curPdu.getColumnIndex("date")); 

        String selectionAddr = new String ("msg_id = '" + id + "'"); 
        Uri uriAddr = Uri.parse ("content://mms/" + id + "/addr"); 
        Cursor curAddr = getContentResolver().query(uriAddr, null, null, null, null); 
        if(curAddr.moveToNext()){ 
            String contact_id = curAddr.getString (curAddr.getColumnIndex ("contact_id")); 
            String address = curAddr.getString (curAddr.getColumnIndex ("address")); 
            String selectionPart = new String ("mid = '" + id + "'"); 
            Cursor curPart = getContentResolver ().query(Uri.parse ("content://mms/part"), null, null, null, null); 
            //Cursor curPart = context.getContentResolver ().query(Uri.parse ("content://mms/" + id + "/part"), null, null, null, null); 

            while(curPart.moveToNext()) 
            { 
                columns = curPart.getColumnNames(); 
                if(values == null) 
                    values = new String[columns.length]; 

                for(int i=0; i< curPart.getColumnCount(); i++){ 
                    values[i] = curPart.getString(i); 
                } 
                String contact_idd = curPart.getString(0); 

                if(values[3].equals("image/jpeg") || values[3].equals("image/bmp") || 
                        values[3].equals("image/gif") || values[3].equals("image/jpg") ||
                        values[3].equals("image/png")) 
                { 
                    GetMmsAttachment(values[0],values[12]); 
                    //Toast.makeText(getApplicationContext(), "Retrieved MMS attachment", Toast.LENGTH_LONG);
                } 
            } 
        } 
    } 
} 

private void GetMmsAttachment(String _id, String _data) 
{ 
    Uri partURI = Uri.parse("content://mms/part/" + _id ); 
    String filePath = "/sdcard/photo.jpg";
    InputStream is = null;
    OutputStream picFile = null;
    Bitmap bitmap = null;

    try { 
        is = getContentResolver().openInputStream(partURI); 
        bitmap = BitmapFactory.decodeStream(is);

        picFile = new FileOutputStream(filePath);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 100, picFile);
        picFile.flush();
        picFile.close();
    } 
    catch (Exception e) 
    { 
        e.printStackTrace(); 
        //throw new MmsException(e); 
    } 
}
解决方案

Figured out myself, the codes are as follows:

private void checkMMSMessages() {

    String[] columns = null; 
    String[] values = null;
    String read = "read = 0";

    Cursor curPdu = getContentResolver().query(Uri.parse("content://mms"), null, read, null, null); 
    if(curPdu.moveToNext()){
        String id = curPdu.getString(curPdu.getColumnIndex("_id"));
        Cursor curPart = getContentResolver().query(Uri.parse ("content://mms/" + id + "/part"), null, null, null, null);

        while(curPart.moveToNext()) 
        { 
            columns = curPart.getColumnNames(); 
            if(values == null) 
                values = new String[columns.length]; 

            for(int i=0; i< curPart.getColumnCount(); i++){ 
                values[i] = curPart.getString(i); 
            } 

            if(values[3].equals("image/jpeg") || values[3].equals("image/bmp") || 
                    values[3].equals("image/gif") || values[3].equals("image/jpg") ||
                    values[3].equals("image/png")) 
            { 
                GetMmsAttachment(values[0],values[12]); 
            } 
        } 
    }
}

private void GetMmsAttachment(String _id, String _data) 
{ 
    Uri partURI = Uri.parse("content://mms/part/" + _id ); 
    String filePath = "/sdcard/photo.jpg";
    InputStream is = null;
    OutputStream picFile = null;
    Bitmap bitmap = null;

    try { 
        is = getContentResolver().openInputStream(partURI); 
        bitmap = BitmapFactory.decodeStream(is);

        picFile = new FileOutputStream(filePath);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 50, picFile);
        picFile.flush();
        picFile.close();
    } 
    catch (Exception e) 
    { 
        e.printStackTrace(); 
        //throw new MmsException(e); 
    } 
}
