Android 仅通过电子邮件共享图像

我制作了一个应用程序，用户在其中打开相机并捕获图像。现在我希望通过电子邮件直接共享该图像。为此，我使用了intents。但我的问题是，当用户finsh捕获图像时，有多种选项，如whatsap、google、gmail、，hike等。我只希望用户只通过电子邮件而不是与其他应用程序共享图像

代码

我建议过滤用户可用于共享文件的选项，并将其限制为仅限于电子邮件应用程序

尝试类似的方法：

Intent emailIntent = new Intent();
    emailIntent.setAction(Intent.ACTION_SEND);
    emailIntent.putExtra(Intent.EXTRA_TEXT, // email body);
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, // email subject);
    // Add Image to email

    PackageManager pm = getPackageManager();
    Intent sendIntent = new Intent(Intent.ACTION_SEND);     
    sendIntent.setType("image/jpg");


    Intent openInChooser = Intent.createChooser(emailIntent, resources.getString(R.string.share_chooser_text));

    List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
    List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();        
    for (int i = 0; i < resInfo.size(); i++) {
        // Extract the label, append it, and repackage it in a LabeledIntent
        ResolveInfo ri = resInfo.get(i);
        String packageName = ri.activityInfo.packageName;
        if(packageName.contains("android.email")) {
            emailIntent.setPackage(packageName);
        } 
            intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
        }
    }

    // convert intentList to array
    LabeledIntent[] extraIntents = intentList.toArray( new LabeledIntent[ intentList.size() ]);

    openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
    startActivity(openInChooser);   

Intent emailIntent=newintent（）；
emailIntent.setAction（Intent.ACTION\u SEND）；
emailIntent.putExtra（Intent.EXTRA_TEXT，//电子邮件正文）；
emailIntent.putExtra（Intent.EXTRA_SUBJECT，//email SUBJECT）；
//将图像添加到电子邮件
PackageManager pm=getPackageManager（）；
Intent sendIntent=新的Intent（Intent.ACTION\U SEND）；
setType（“image/jpg”）；
Intent openInChooser=Intent.createChooser（emailIntent，resources.getString（R.string.share\u chooser\u text））；
List resInfo=pm.querytentActivities（sendIntent，0）；
List intentList=new ArrayList（）；
对于（int i=0；i

首先将图像保存在SD卡或电话商店中，然后发送电子邮件如果先生我不想保存该img，只需通过电子邮件直接共享即可。这很好，但不直接通过电子邮件发送图像。好的，您不需要将图像保存在SD卡中，然后从位图中的url下载图像，然后通过电子邮件发送位图。Gmail和hotmail呢？

Intent emailIntent = new Intent();
    emailIntent.setAction(Intent.ACTION_SEND);
    emailIntent.putExtra(Intent.EXTRA_TEXT, // email body);
    emailIntent.putExtra(Intent.EXTRA_SUBJECT, // email subject);
    // Add Image to email

    PackageManager pm = getPackageManager();
    Intent sendIntent = new Intent(Intent.ACTION_SEND);     
    sendIntent.setType("image/jpg");


    Intent openInChooser = Intent.createChooser(emailIntent, resources.getString(R.string.share_chooser_text));

    List<ResolveInfo> resInfo = pm.queryIntentActivities(sendIntent, 0);
    List<LabeledIntent> intentList = new ArrayList<LabeledIntent>();        
    for (int i = 0; i < resInfo.size(); i++) {
        // Extract the label, append it, and repackage it in a LabeledIntent
        ResolveInfo ri = resInfo.get(i);
        String packageName = ri.activityInfo.packageName;
        if(packageName.contains("android.email")) {
            emailIntent.setPackage(packageName);
        } 
            intentList.add(new LabeledIntent(intent, packageName, ri.loadLabel(pm), ri.icon));
        }
    }

    // convert intentList to array
    LabeledIntent[] extraIntents = intentList.toArray( new LabeledIntent[ intentList.size() ]);

    openInChooser.putExtra(Intent.EXTRA_INITIAL_INTENTS, extraIntents);
    startActivity(openInChooser);
