要搜索特定号码的通话记录，可以使用以下代码示例：

public ArrayList searchCallLogs(Context context, String phoneNumber) {
    ArrayList callLogs = new ArrayList<>();
    
    // 获取通话记录的URI
    Uri callUri = CallLog.Calls.CONTENT_URI;
    
    // 定义要查询的字段
    String[] projection = new String[]{
            CallLog.Calls.NUMBER,
            CallLog.Calls.DATE,
            CallLog.Calls.DURATION,
            CallLog.Calls.TYPE
    };
    
    // 设置查询条件
    String selection = CallLog.Calls.NUMBER + " = ?";
    String[] selectionArgs = new String[]{ phoneNumber };
    
    // 查询通话记录
    Cursor cursor = context.getContentResolver().query(
            callUri,
            projection,
            selection,
            selectionArgs,
            CallLog.Calls.DATE + " DESC"
    );
    
    // 遍历查询结果
    if (cursor != null && cursor.moveToFirst()) {
        do {
            String number = cursor.getString(cursor.getColumnIndex(CallLog.Calls.NUMBER));
            String date = cursor.getString(cursor.getColumnIndex(CallLog.Calls.DATE));
            String duration = cursor.getString(cursor.getColumnIndex(CallLog.Calls.DURATION));
            String type = cursor.getString(cursor.getColumnIndex(CallLog.Calls.TYPE));
            
            // 将通话记录添加到列表中
            callLogs.add("Number: " + number + ", Date: " + date + ", Duration: " + duration + ", Type: " + type);
        } while (cursor.moveToNext());
        
        cursor.close();
    }
    
    return callLogs;
}

要使用上述代码示例，可以在Android应用的活动或片段中调用searchCallLogs方法，并传入要搜索的电话号码。该方法将返回一个包含匹配的通话记录的字符串列表。请确保在使用此代码之前已经获取了通话记录的读取权限。

示例用法：

ArrayList callLogs = searchCallLogs(getApplicationContext(), "9876543210");

for (String callLog : callLogs) {
    Log.d("Call Log", callLog);
}

这将打印出与电话号码"9876543210"相关的通话记录。
