从另一个类接收数据并通过邮件发送 - Android

Question

我的代码很简单，我需要通过邮件发送从openweathermap下载的数据。

Barometr.java：

public void getPressure(JSONObjesc jObject){
    try{
        JSONObject cis = jObject.getJSONObject("main");
        pressure = cis.getInt("pressure");
    }catch(Exception e){
        Log.e("Barometr", "Error");
    }
}

BarometrActivity（主要类）：

private void showMailDialog(){
    AlertDialog.Builder sendmail = new AlertDialog.Builder(this);
    sendmail.setTitle("Send mail to:");
    final EditText adress = new EditText(this);
    adress.setInputType(InputType.TYPE_CLASS_TEXT);
    sendmail.setView(adress);
    sendmail.setPositiveButton("Send", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            Intent mail = new Intent(Intent.ACTION_SEND);
            mail.setType("text/plain");
            mail.putExtra(Intent.EXTRA_EMAIL, new String[] {adress.getText().toString()});
            mail.putExtra(Intent.EXTRA_SUBJECT, "Pressure");
            mail.putExtra(Intent.EXTRA_TEXT, "sample");
            try {
                startActivity(Intent.createChooser(mail, "Send mail"));
            } catch (android.content.ActivityNotFoundException ex) {
                Toast.makeText(BarometrActivity.this, "Missing app.", Toast.LENGTH_SHORT).show();
            }
        }
    });
    sendmail.show();
}

我想在电子邮件中提供带有样本描述的压力信息。

你能告诉我怎么办？
