如何在Android视频通话SDK中添加视频通话历史记录?

在Android视频通话SDK中添加视频通话历史记录是一个非常有用的功能,它可以帮助用户快速回顾过去的通话记录,提高用户体验。下面,我将详细介绍如何在Android视频通话SDK中添加视频通话历史记录。

一、了解视频通话历史记录功能

视频通话历史记录功能主要包括以下内容:

  1. 通话时间:记录每次通话的开始时间和结束时间。

  2. 通话时长:记录每次通话的时长。

  3. 通话对象:记录每次通话的对方信息,如昵称、头像等。

  4. 通话状态:记录每次通话的状态,如正在进行、已接通、未接通等。

  5. 通话类型:记录每次通话的类型,如视频通话、语音通话等。

二、实现视频通话历史记录功能

  1. 数据库设计

首先,我们需要设计一个数据库来存储视频通话历史记录。在Android中,我们可以使用SQLite数据库来实现。以下是一个简单的数据库设计示例:

CREATE TABLE call_history (
id INTEGER PRIMARY KEY AUTOINCREMENT,
caller_id INTEGER,
callee_id INTEGER,
call_time DATETIME,
call_duration INTEGER,
call_status INTEGER,
call_type INTEGER
);

  1. 数据库操作

在Android中,我们可以使用SQLiteOpenHelper类来创建和管理数据库。以下是一个示例代码,用于创建数据库和表:

public class DatabaseHelper extends SQLiteOpenHelper {

private static final String DATABASE_NAME = "call_history.db";
private static final int DATABASE_VERSION = 1;

public DatabaseHelper(Context context) {
super(context, DATABASE_NAME, null, DATABASE_VERSION);
}

@Override
public void onCreate(SQLiteDatabase db) {
String CREATE_CALL_HISTORY_TABLE = "CREATE TABLE call_history (" +
"id INTEGER PRIMARY KEY AUTOINCREMENT," +
"caller_id INTEGER," +
"callee_id INTEGER," +
"call_time DATETIME," +
"call_duration INTEGER," +
"call_status INTEGER," +
"call_type INTEGER" +
")";
db.execSQL(CREATE_CALL_HISTORY_TABLE);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
db.execSQL("DROP TABLE IF EXISTS call_history");
onCreate(db);
}
}

  1. 保存通话历史记录

在视频通话结束后,我们需要将通话历史记录保存到数据库中。以下是一个示例代码,用于保存通话历史记录:

public void saveCallHistory(int callerId, int calleeId, long callTime, int callDuration, int callStatus, int callType) {
SQLiteDatabase db = dbHelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put("caller_id", callerId);
values.put("callee_id", calleeId);
values.put("call_time", callTime);
values.put("call_duration", callDuration);
values.put("call_status", callStatus);
values.put("call_type", callType);
db.insert("call_history", null, values);
db.close();
}

  1. 查询通话历史记录

在需要查询通话历史记录时,我们可以使用以下代码:

public List getAllCallHistory() {
List callHistoryList = new ArrayList<>();
SQLiteDatabase db = dbHelper.getReadableDatabase();
Cursor cursor = db.query("call_history", null, null, null, null, null, null);
if (cursor.moveToFirst()) {
do {
int id = cursor.getInt(cursor.getColumnIndex("id"));
int callerId = cursor.getInt(cursor.getColumnIndex("caller_id"));
int calleeId = cursor.getInt(cursor.getColumnIndex("callee_id"));
long callTime = cursor.getLong(cursor.getColumnIndex("call_time"));
int callDuration = cursor.getInt(cursor.getColumnIndex("call_duration"));
int callStatus = cursor.getInt(cursor.getColumnIndex("call_status"));
int callType = cursor.getInt(cursor.getColumnIndex("call_type"));
CallHistory callHistory = new CallHistory(id, callerId, calleeId, callTime, callDuration, callStatus, callType);
callHistoryList.add(callHistory);
} while (cursor.moveToNext());
}
cursor.close();
db.close();
return callHistoryList;
}

  1. 展示通话历史记录

最后,我们需要在UI界面展示通话历史记录。以下是一个简单的示例代码,用于在RecyclerView中展示通话历史记录:

public class CallHistoryAdapter extends RecyclerView.Adapter {

private List callHistoryList;

public CallHistoryAdapter(List callHistoryList) {
this.callHistoryList = callHistoryList;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.call_history_item, parent, false);
return new ViewHolder(view);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
CallHistory callHistory = callHistoryList.get(position);
holder.callerName.setText(callHistory.getCallerName());
holder.calleeName.setText(callHistory.getCalleeName());
holder.callTime.setText(callHistory.getCallTime());
holder.callDuration.setText(callHistory.getCallDuration());
}

@Override
public int getItemCount() {
return callHistoryList.size();
}

public static class ViewHolder extends RecyclerView.ViewHolder {
public TextView callerName;
public TextView calleeName;
public TextView callTime;
public TextView callDuration;

public ViewHolder(View itemView) {
super(itemView);
callerName = itemView.findViewById(R.id.caller_name);
calleeName = itemView.findViewById(R.id.callee_name);
callTime = itemView.findViewById(R.id.call_time);
callDuration = itemView.findViewById(R.id.call_duration);
}
}
}

通过以上步骤,我们就可以在Android视频通话SDK中添加视频通话历史记录功能了。这样,用户就可以方便地查看和回顾过去的通话记录,提高用户体验。
