Android 如何使用我的应用程序发送的电子邮件的价值打开Gmail应用程序并自动填写Gmail？

我正在创建一个应用程序，在其中查看某人的个人资料时，我希望在单击浮动操作栏后将用户发送到电子邮件

  Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto","example@example.com", null));
  emailIntent.putExtra(Intent.EXTRA_SUBJECT, "your subject here");
  emailIntent.putExtra(Intent.EXTRA_TEXT, "if you want append some text");
  startActivity(Intent.createChooser(emailIntent, "Send email..."));

我可以打开gmail，但我没有电子邮件的价值已经填写，尽管发送它的价值

  Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto","example@example.com", null));
  emailIntent.putExtra(Intent.EXTRA_SUBJECT, "your subject here");
  emailIntent.putExtra(Intent.EXTRA_TEXT, "if you want append some text");
  startActivity(Intent.createChooser(emailIntent, "Send email..."));

代码：

fabtoemail.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Intent emailIntent = new Intent(android.content.Intent.ACTION_SEND);
                String aEmail = email;
                emailIntent.putExtra(android.content.Intent.EXTRA_EMAIL, aEmail);
                emailIntent.setType("plain/text");
                startActivity(Intent.createChooser(emailIntent, "Select Application"));
            }
        });

  Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto","example@example.com", null));
  emailIntent.putExtra(Intent.EXTRA_SUBJECT, "your subject here");
  emailIntent.putExtra(Intent.EXTRA_TEXT, "if you want append some text");
  startActivity(Intent.createChooser(emailIntent, "Send email..."));

像这样试试

  Intent emailIntent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("mailto","example@example.com", null));
  emailIntent.putExtra(Intent.EXTRA_SUBJECT, "your subject here");
  emailIntent.putExtra(Intent.EXTRA_TEXT, "if you want append some text");
  startActivity(Intent.createChooser(emailIntent, "Send email..."));

虽然这段代码可能会回答这个问题，但您应该添加一个解释，说明为什么/如何解决这个问题。是的，我的错。我只是觉得那些台词不需要解释，但我想这不是这样思考的地方。
