使用SimpleChatView实现公屏效果。实现效果如下：

用法

Step 1

在你的build.gradle中添加依赖。

implementation 'com.ryan.chatlib:chatlib:0.0.5'

Step 2

在你的layout文件中使用SimpleChatView。

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/cl_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.ryan.chatlib.SimpleChatView
        android:id="@+id/chat"
        android:layout_width="match_parent"
        android:layout_height="300dp"
        android:layout_marginBottom="45dp"
        android:layout_marginEnd="100dp"
        android:layout_marginLeft="@dimen/dp5"
        android:layout_marginRight="100dp"
        android:layout_marginStart="@dimen/dp5"
        app:layout_constraintBottom_toBottomOf="parent" />

</android.support.constraint.ConstraintLayout>

Step 3

定义你的数据接口，需要继承BaseChatMsg，如创建MyChatMsg:

public class MyChatMsg extends BaseChatMsg {
	public int type;
	public String content;
}

Step 4

创建适配器，需要继承BaseChatAdapter，并把数据接口传入，因为BaseChatAdapter使用的是继承于BaseChatMsg的泛型，所以需要把你定义的数据接口传入，如创建SimpleChatAdapter：

public class SimpleChatAdapter extends BaseChatAdapter<MyChatMsg> {
	
	// 实现RecyclerView.Adapter必须实现的接口
	...

	// 还需要实现这三个接口
	@Override
    public synchronized void removeItems(int startPos, int endPos) {
        mDatas.subList(startPos, endPos).clear();
        notifyItemRangeRemoved(1, (endPos - startPos));
    }


    @Override
    public synchronized void addItem(MyChatMsg chatMsg) {
        mDatas.add(chatMsg);
        notifyItemInserted(getItemCount());
    }

    @Override
    public synchronized void addItemList(List<MyChatMsg> list) {
        int startPos = getItemCount();
        int addSize = ListUtils.isEmpty(list) ? 0 : list.size();
        mDatas.addAll(list);
        notifyItemRangeInserted(startPos, addSize);
    }
}

Step 5

在Activity创建完成之后，通过id绑定SimpleChatView，然后创建适配器，最后调用提供接口即可。

mChatView = findViewById(R.id.chat);

SimpleChatAdapter adapter = new SimpleChatAdapter(null);
mChatView
        // 设置Adapter
        .setAdapter(adapter)
        // 设置缓冲时间50ms
        .setBufferTime(50)
        // 最后调用setUp
        .setUp();

在你需要释放资源的地方调用release()方法，释放资源：

@Override
protected void onDestroy() {
    super.onDestroy();

    if (mChatView != null) {
        mChatView.release();
    }
}

API

  1. setAdapter(T mBaseAdapter：设置适配器
  2. sendSingleMsg(D msg)：发送单条消息
  3. sendMultiMsg(List<D> datas)：发送多条消息
  4. setBufferTime(@IntRange(from = 0) int bufferTime)：设置缓冲时间，单位ms
  5. setUp()：装载，必须最后调用
  6. release()：释放资源
