Answer 1

您可以使用此代码。它可以解决您的问题： startActivity(new Intent(Menu.this, Email .class));

Answer 2

尝试将您的emailIntent.setType("Plain/Text");更改为emailIntent.setType("text/html"); 并进行以下更改可能会对您有所帮助

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

Answer 3

试试这个：

startActivity(new Intent("com.guess.guessme.Email"));

并确保电子邮件活动也在您的清单文件中说明。

Answer 4

试试吧

 emailIntent.setType("message/rfc822");
 Email.this.startActivity(Intent.createChooser(email, "Choose an Email client :");

Answer 5

尝试这样做 -

看来你正在实施错误的倾听者。尝试导入OnClickListener而不是View.OnClickListener，如下所示 -

public class Email extends Activity implements OnClickListener

以下代码。

public void onClick(View v) {
    // TODO Auto-generated method stub

switch(v.getId())
{

case R.id.bSentEmail:

    convertEditTextVarsIntoStringsAndYesThisIsAMethodWeCreated();
    String emailaddress[] = { emailAdd };
    String message = "Well hello "
            + name
            + " I just wanted to say "
            + beginning
            + ".  Not only that but I hate when you "
            + stupidAction
            + ", that just really makes me crazy.  I just want to make you "
            + hatefulAct
            + ".  Welp, thats all I wanted to chit-chatter about, oh and"
            + out
            + "Oh and you could visit facebook www.facebook.com/"
            + '\n' + "PS. I think I love you...    ";

    Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
    emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, emailaddress);
    emailIntent.putExtra(android.content.Intent.EXTRA_SUBJECT,"I hate you");
    emailIntent.setType("Plain/Text");
    emailIntent.putExtra(android.content.Intent.EXTRA_TEXT,message);
    startActivity(emailIntent);

break;
}

}
