((HomeActivity) getActivity()).contactus 
       .setOnClickListener(new OnClickListener() { 

        @Override 
        public void onClick(View arg0) { 
         // TODO Auto-generated method stub 
         sendEmail(); 
        } 
       }); 

     ((HomeActivity) getActivity()).attachmentimageview 
       .setOnClickListener(new OnClickListener() { 

        @Override 
        public void onClick(View arg0) { 
         Intent intent = new Intent(
           Intent.ACTION_PICK, 
           android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI); 

         intent.setType("image/*"); 
         intent.setAction(Intent.ACTION_GET_CONTENT); 

         startActivityForResult(

           MY_INTENT_CLICK); 
        } 
       }); 

     return view; 
    } 

    @Override 
    public void onActivityResult(int requestCode, int resultCode, Intent data) { 
     if (resultCode == Activity.RESULT_OK) { 
      if (requestCode == MY_INTENT_CLICK) { 
       if (null == data) 
        return; 

       String selectedImagePath; 
       Uri selectedImageUri = data.getData(); 

       // MEDIA GALLERY 
       selectedImagePath = ImageFilePath.getPath(
         getActivity(), selectedImageUri); 
       Log.i("Image File Path", "" + selectedImagePath); 
//    txta.setText("File Path : \n" + selectedImagePath); 
      } 
     } 
    } 

    private void sendEmail() { 
     try { 


      Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND); 
      String[] recipients = new String[] { "Enter email" }; 
      emailIntent 
        .putExtra(android.content.Intent.EXTRA_EMAIL, recipients); 
      emailIntent 
        .putExtra(
          Intent.EXTRA_EMAIL, 
          new String[] { "anilkumar@softageindia.com,danyalozair@gmail.com" }); 
      emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, 
        "Feedback"); 

      emailIntent.putExtra(Intent.EXTRA_STREAM, selectedImagePath); 

      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, 
        Html.fromHtml("")); 
      emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, "HI" 
        + "\n\n" + contactustext.getText().toString()); 
      emailIntent.setType("message/rfc822"); 
      startActivity(emailIntent); 
     } catch (Exception e) { 
      e.printStackTrace(); 
     } 
    } 

這是我的代碼，我想我使用給定的代碼，我能夠從廚房拿到路徑從SD卡或畫廊附加文件附加在Android的文件但是，當我在與我們聯繫按鈕則點擊如果我們不使用附件，那麼它與文本正常工作相同的工作，以獲得文件目錄，請檢查哪裏做錯了，如何解決它，請建議我actully我想發送一些文本，並附件發送通過Gmail時，當我點擊按鈕聯繫我們它重定向到附件和文本到Gmail，然後我們可以發送它。

Answer 1

首先，在您的Activity或Fragment之外的onCreate

public static void getVcardString() { 

String path = null;  
String vfile = null; 

vfile = "Contacts.vcf";   
Cursor phones = mContext.getContentResolver().query(ContactsContract.CommonDataKinds.Phone.CONTENT_URI, null, 
       null, null, null); 

phones.moveToFirst(); 
Log.i("Number of contacts", "cursorCount" +phones.getCount()); 
for(int i =0;i<phones.getCount();i++) {  

    String lookupKey = phones.getString(phones.getColumnIndex(ContactsContract.Contacts.LOOKUP_KEY)); 
    Log.i("lookupKey", " " +lookupKey); 
    Uri uri = Uri.withAppendedPath(ContactsContract.Contacts.CONTENT_VCARD_URI, lookupKey); 
    AssetFileDescriptor fd; 

    try { 
     fd = mContext.getContentResolver().openAssetFileDescriptor(uri, "r"); 
     FileInputStream fis = fd.createInputStream(); 
     byte[] buf = new byte[(int) fd.getDeclaredLength()]; 
     fis.read(buf); 
     String VCard = new String(buf);   

     path = Environment.getExternalStorageDirectory().toString() + File.separator + vfile; 
     FileOutputStream mFileOutputStream = new FileOutputStream(path, true); 
     mFileOutputStream.write(VCard.toString().getBytes());  

     phones.moveToNext();    

     filevcf = new File(path); 
     Log.i("file", "file" +filevcf); 

    }catch(Exception e1) { 
     e1.printStackTrace(); 
    } 
}  
Log.i("TAG", "No Contacts in Your Phone");   
} 

創建這個方法並調用它裏面onCreate，如：再

public void onCreate(Bundle savedInstanceState) { 
super.onCreate(savedInstanceState); 
setContentView(R.layout.main);  
getVcardString();   
}  

而現在，創建一個新的方法外送EmailonCreate like：

protected void data() {    
File filelocation = filevcf ;  
Intent sharingIntent = new Intent(Intent.ACTION_SEND); 
sharingIntent.setType("vnd.android.cursor.dir/email");  
sharingIntent.setType("application/x-vcard");  
sharingIntent.putExtra(Intent.EXTRA_EMAIL, "mail@gmail.com");   
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+filelocation.getAbsolutePath())); 
startActivity(Intent.createChooser(sharingIntent, "Send email"));    
} 

並稱之爲data()您發送電子郵件按鈕的方法onClick像：

data(); 

請告知，如果你現在得到的任何問題，我知道。

，您可以附加文件：

Intent sharingIntent = new Intent(Intent.ACTION_SEND); 
sharingIntent.setType("vnd.android.cursor.dir/email");  
sharingIntent.putExtra(Intent.EXTRA_SUBJECT, "Please find attachment"); 
sharingIntent.putExtra(Intent.EXTRA_STREAM, Uri.parse("file://"+"you file's path")); 
startActivity(Intent.createChooser(sharingIntent, "Attach using..."));
