电子邮件意图电子邮件选择器

Question

我的申请有问题。该应用程序的目的是收集数据并使用javamail将数据表单提交到指定的电子邮件地址。当用户单击该按钮时，他们应该收到一个选择电子邮件客户端的提示，但是在测试该提示时我没有收到此提示。有人可以告诉我我想念什么吗？

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Spinner;
import android.widget.TextView;

public class SubmitForm extends Activity implements View.OnClickListener {
private Intent emailIntent;
EditText personsFirstName, personsLastName, personsEmail, personsPhone, comments, vehicleModel;
Spinner vehicleYear, vehicleMake, serviceTime, serviceNeeded;
TextView serviceDate;
String fname, lname, emailAdd, phoneNumber, vehicleYears, vehicleModeltrim, vehicleManu, serviceAppointment, serviceAppointmentTime, serviceTypeNeeded, extraComments;
Button sendEmail;

@Override
protected void onCreate(Bundle savedInstanceState) {
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.service);
    initializeVars();
    sendEmail.setOnClickListener(this);
}

    // TODO Auto-generated method stub

    String emailaddress[] = { emailAdd };
    String message = "Please Review the following"

            + '\n' + "Service Needed: " + serviceTypeNeeded
            + '\n' + "Comments: " + extraComments;

    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.setType("plain/text");
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, new String[] {"[email protected]"});

    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailaddress);
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Schedule Service Request");

    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT, message);
    startActivity(Intent.createChooser(emailIntent, "Please select Email Client"));

    // TODO Auto-generated method stub

    fname = personsFirstName.getText().toString();
    lname = personsLastName.getText().toString();
    emailAdd = personsEmail.getText().toString();
    phoneNumber = personsPhone.getText().toString();

    //vehicleYears = vehicleYear.getText().toString();
    vehicleYears = (String) vehicleYear.getAdapter().getItem(RESULT_OK);


    //vehicleManu = vehicleMake.getText().toString();
    vehicleManu = (String) vehicleMake.getAdapter().getItem(RESULT_OK);

    vehicleModeltrim = vehicleModel.getText().toString();
    serviceAppointment = serviceDate.getText().toString();
    serviceAppointmentTime = (String) serviceTime.getAdapter().getItem(RESULT_OK);


    //serviceTypeNeeded = serviceNeeded.getText().toString();
    serviceTypeNeeded = (String) serviceNeeded.getAdapter().getItem(RESULT_OK);

    extraComments = comments.getText().toString();
}
@Override
protected void onPause() {
    // TODO Auto-generated method stub
    super.onPause();
    finish();
}
}

如果您只想在设备上安装的电子邮件客户端中进行选择，则可以使用ACTION_SENTTO选项

String mailTo="[email protected]";
Intent email_intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",mailTo, null)); 
email_intent.putExtra(android.content.Intent.EXTRA_SUBJECT, "Subject text here"); 
email_intent.putExtra(android.content.Intent.EXTRA_TEXT,"Body text here"); 

startActivity(Intent.createChooser(email_intent, "Send email..."));

尝试在真实设备上使用此电子邮件意图...模拟器可能无法为您提供结果。

祝你好运.. >>
