我的Android外卖应用程序不能在Gmail中填充主题和正文文本，但适用于Outlook

Question

我已经在Android Studio中创建了一个Android外卖订购应用程序，它应该通过电子邮件发送订单，并填写主题和文本正文字段。当我通过Outlook发送邮件时，它会这样做，但当我在模拟器、手机(Android 10)和平板电脑(Android 7)上使用Android G邮件客户端时，它会拒绝填写这些字段-它只会发送一封空白电子邮件。

public void submitOrder(View view) {
    submit_order_quantity = submit_order_quantity + 1;
    EditText enterName = findViewById(R.id.nameBar);
    String showName = enterName.getText().toString(); //gets you the contents of name edit text
    EditText enterTelephone = findViewById(R.id.your_telephone);
    String showPhone = enterTelephone.getText().toString(); //gets you the contents of telephone number edit text
    EditText enterTime = findViewById(R.id.collect_time);
    String showTime = enterTime.getText().toString(); //gets you the contents of telephone number edit text


    double totalPrice = calculatePrice();
    String priceMessage = createOrderSummary(showName, showPhone, showTime, totalPrice);

    if(submit_order_quantity == 1 && totalPrice != 0){
        Intent intent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto",         "emailaddress@email.com", null));
        // only email apps should handle this
         intent.putExtra(Intent.EXTRA_SUBJECT, Restaurant Order for: + showName);
         intent.putExtra(Intent.EXTRA_TEXT, priceMessage);
         startActivity(Intent.createChooser(intent, "Send email..."));
    }
}

showName是EditText enterName的toString结果

showPhone是EditText enterTelephone的toString结果

showTime是EditText enterTime的toString结果

totalPrice是商品的价格乘以每个商品的数量作为一系列字符串来创建priceMessage的结果

像这样创建你的意图，这对我的应用程序分享到Gmail很有效：

final Intent intent = new Intent(Intent.ACTION_SEND);
intent.setType("text/plain");
intent.putExtra(Intent.EXTRA_EMAIL, new String[]{"emailaddress@email.com"});
