我正在开发一个用于发送带有语音识别界面的短信的安卓应用程序。我正面临从语音识别界面显示结果的问题。我无法在消息列(编辑文本)中显示结果(转换后的文本)。但是当我在窗口中提供文本视图时,我可以在文本字段中显示结果。所以请帮助我在编辑文本字段中获得结果。
代码

ttxt.setText("");
} catch (ActivityNotFoundException a) {
Toast t = Toast.makeText(getApplicationContext(),
"Opps! Your device doesn't support Speech to Text",
Toast.LENGTH_SHORT);
t.show();
}

// ---sends an SMS message to another device---

sms.sendTextMessage(phoneNumber, null, message, null, null);
