如何在android中的编辑文本字段中显示结果

Question

我正在开发一个用于发送带有语音识别界面的短信的Android应用程序。我正面临着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。

试试这个：

EditText editText = (EditText)findViewById(R.id.edit_text);
editText.setText("Google is your friend.", TextView.BufferType.EDITABLE);
