一个 ListView 的不同布局

你好。有一个聊天活动，其中包含ListView消息。对于ListViewitem'a，有两种样式：左侧的消息（来自对话者），右侧的消息（您的）。

有一段代码，在给定的 URI 处，从服务器接收 JSON，它被解析为消息，然后解析为ListView项目。

JSON 看起来像这样：author:"author",reciever:"reciever",time:"time",content:"content"

所以，我需要根据谁拥有消息，它在ListView. 那些。如果我们收到消息，则ListViewitem'a 的样式在左侧，如果我们发送消息，则在右侧。（与所有使者一样）。

private class ListViewLoaderTask extends AsyncTask<String, Void, SimpleAdapter> {

    JSONObject jObject;

    @Override
    protected SimpleAdapter doInBackground(String... strJson) {
        try {
            jObject = new JSONObject(strJson[0]);
            parse(jObject);
        } catch (Exception e) {
            Log.d("JSON Exception1", e.toString());
        }


        List<HashMap<String, Object>> messages = null;

        try {
            messages = parse(jObject);
        } catch (Exception e) {
            Log.d("Exception", e.toString());
        }

        String[] from = {"content", "time", "author"};
        int[] to = {R.id.contentMSG, R.id.timeMSG, R.id.usernameMSG};

        /*
            Вот здесь нужно исходя из того, кто автор сообщения,
            выбрать layout

         */
        SimpleAdapter adapter = new SimpleAdapter(getBaseContext(), messages, R.layout.one_msg_item, from, to);
        adapter.notifyDataSetChanged();

        return adapter;
    }


}


public List<HashMap<String, Object>> parse(JSONObject jObject) {

    JSONArray jMessages = null;
    try {
        jMessages = jObject.getJSONArray("Messages");
    } catch (JSONException | NullPointerException e) {
        e.printStackTrace();
    }

    return getMessages(jMessages);
}

private List<HashMap<String, Object>> getMessages(JSONArray jMessages) {
    List<HashMap<String, Object>> messagesList = new ArrayList<HashMap<String, Object>>();
    HashMap<String, Object> message = null;

    for (int i = 0; i < jMessages.length(); i++) {
        try {
            message = getMessage((JSONObject) jMessages.get(i));
            messagesList.add(message);

        } catch (JSONException | NullPointerException e) {
            e.printStackTrace();
        }
    }
    return messagesList;
}


private HashMap<String, Object> getMessage(JSONObject jMessage) {
    HashMap<String, Object> message = new HashMap<String, Object>();
    String author = "";
    String client = "";
    String time = "";
    String content = "";
    try {
        author = jMessage.getString("author");
        client = jMessage.getString("client");
        time = jMessage.getString("time");
        content = jMessage.getString("content");

        message.put("author", author);
        message.put("client", client);
        message.put("time", time);
        message.put("content", content);

    } catch (JSONException e) {
        e.printStackTrace();
    }
    return message;
}
