"1、获取输入框控件EditText，需要自定义会话页面

public class ChatConversationFragment extends ConversationFragment {

private RelativeLayout containerView;

private RongExtension extension;

private EditText inputEditText;

@Override

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

containerView = (RelativeLayout) super.onCreateView(inflater, container, savedInstanceState);

extension = (RongExtension) containerView.findViewById(io.rong.imkit.R.id.rc_extension);

inputEditText = extension.getInputEditText();

return containerView;

}

}

注意：在添加会话页面的时候：

<fragment

android:id=“@+id/conversation”

android:name=“所在路径.ChatConversationFragment”

android:layout_width=“match_parent”

android:layout_height=“match_parent” />

2、调用EditText相关方法设置hint和样式"
