我正在使用RecyclerView
进行聊天。请注意下面附带的屏幕截图,以便更好地理解问题:
图片-1
图片-2
现在,问题是当键盘打开时,用户必须能够看到最后发送/接收的消息,但是在image-2
中,正如您所看到的,{{1}的滚动位置在早先的消息中。
我尝试了一些变化:
RecyclerView
更改了RecyclerView的smoothScroll,android:windowSoftInputMode="adjustResize"
我该怎么做才能解决这个问题,以便在键盘打开时收到最后一条消息?
修改-1
这是我的适配器的代码:
CustomAdapter.class
rview.smoothScrollToPosition(adapter_data.size());
chat_message.xml
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.FeedsViewHolder>
{
DataHolder d1 = new DataHolder();
public class FeedsViewHolder extends RecyclerView.ViewHolder
{
private TextView chat;
private Typeface face;
FeedsViewHolder(View itemView)
{
super(itemView);
chat = (TextView)itemView.findViewById(R.id.chatMessage);
face = Typeface.createFromAsset(itemView.getContext().getAssets(), "Fonts/Roboto-Regular.ttf");
chat.setTypeface(face);
}
}
private static class DataHolder
{
List<Text> feeds;
}
CustomAdapter(List<Text> feeds)
{
this.d1.feeds = feeds;
}
@Override
public void onAttachedToRecyclerView(RecyclerView recyclerView) {
super.onAttachedToRecyclerView(recyclerView);
}
@Override
public FeedsViewHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.chat_message, viewGroup, false);
FeedsViewHolder pvh = new FeedsViewHolder(v);
return pvh;
}
@Override
public void onBindViewHolder(FeedsViewHolder feedViewHolder, int i)
{
RelativeLayout.LayoutParams params =
(RelativeLayout.LayoutParams)feedViewHolder.chat.getLayoutParams();
if(d1.feeds.get(i).isMachineOrHuman())
{
params.addRule(RelativeLayout.ALIGN_PARENT_START);
feedViewHolder.chat.setLayoutParams(params);
feedViewHolder.chat.setBackgroundResource(R.drawable.user);
feedViewHolder.chat.setText(d1.feeds.get(i).getMessage());
}
else
{
params.addRule(RelativeLayout.ALIGN_PARENT_END);
feedViewHolder.chat.setLayoutParams(params);
feedViewHolder.chat.setBackgroundResource(R.drawable.ais);
feedViewHolder.chat.setText(d1.feeds.get(i).getMessage());
}
}
@Override
public int getItemCount()
{
if(d1.feeds!=null)
{
return d1.feeds.size();
}
else
{
return 0;
}
}
}
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/chat_rel"
android:layout_width="match_parent"
android:layout_height="wrap_content">
<TextView android:id="@+id/chatMessage"
android:layout_width="wrap_content"
android:layout_marginTop="10dp"
android:layout_marginBottom="10dp"
android:layout_marginStart="10dp"
android:layout_marginEnd="10dp"
android:gravity="start"
android:textSize="15sp"
android:textColor="#ffffff"
android:layout_height="wrap_content"
xmlns:android="http://schemas.android.com/apk/res/android" />
在这里工作得很完美,但问题与android:windowSoftInputMode="adjustResize"
有关,我正在寻找一种以键盘弹出方式滚动到RecyclerView
末尾的编程方式。
