如何从SD卡中的文件夹发送附件？

请尝试下面的代码

public void clickbutton(View v) {
try {
strFile = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/temp";

File file = new File(strFile);
if (!file.exists())
file.mkdirs();
strFile = strFile + "/report.html";
createFile();
//
Log.i(getClass().getSimpleName(), "send  task - start");
//
final Intent emailIntent = new Intent(
android.content.Intent.ACTION_SEND);
//
address = "hamdy.ghanem@gmail.com";
subject = "Recite";
emailtext = "Please check the attached recite";
//
emailIntent.setType("plain/text");

emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
new String[] { address });

emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);

emailIntent.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file://" + strFile));

emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext);

this.startActivity(Intent
.createChooser(emailIntent, "Send mail..."));

} catch (Throwable t) {
Toast.makeText(this, "Request failed: " + t.toString(),
Toast.LENGTH_LONG).show();
}
}public void clickbutton(View v) {
try {
strFile = Environment.getExternalStorageDirectory()
.getAbsolutePath() + "/temp";

File file = new File(strFile);
if (!file.exists())
file.mkdirs();
strFile = strFile + "/report.html";
createFile();
//
Log.i(getClass().getSimpleName(), "send  task - start");
//
final Intent emailIntent = new Intent(
android.content.Intent.ACTION_SEND);
//
address = "hamdy.ghanem@gmail.com";
subject = "Recite";
emailtext = "Please check the attached recite";
//
emailIntent.setType("plain/text");

emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL,
new String[] { address });

emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, subject);

emailIntent.putExtra(Intent.EXTRA_STREAM,
Uri.parse("file://" + strFile));

emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, emailtext);

this.startActivity(Intent
.createChooser(emailIntent, "Send mail..."));

} catch (Throwable t) {
Toast.makeText(this, "Request failed: " + t.toString(),
Toast.LENGTH_LONG).show();
}
}

在发送文件时查看此链接

，然后需要将

Uri

对象作为

EXTRA\u流

传递给。因此，您需要通过

Uri=Uri.parse（新文件（您的文件路径））

访问它，并且需要使用

emailIntent.putExtra（Intent.EXTRA_-STREAM，Uri）请参考此链接嗨Anjali，您是否在您的终端测试过此代码？这有用吗？看看代码在做什么，问了什么问题。
