>错误：
android.support.v7.widget.AppCompatEditText{8701551bVFED..CL. .......484,0-747,118 #7f0b006c 应用：ID/name_text
我正在尝试在注册期间将用户名信息设置为FirebaseUser"DisplayName"。我是Android，java和Firebase的新手。但尽管我进行了所有研究，但还是找不到任何解决方案。id/name_text 是编辑文本，它从注册表中的用户那里获取名称。我以为这是一个字符串问题，但无法解决。
帮助。谢谢。
这是代码。

>如果视图不为 null，则String.valueOf(mNameEditText)等效于 mNameEditText.toString()。您可能正在寻找mNameEditText.getText().toString()，它为您提供了EditText元素的内容。
我能够通过以下方式解决问题：
我只是用了mNameEditText.getText().toString().我忘记了中间的.getText()。
