美好的一天Android Studio錯誤的第一個參數類型。找到'java.lang.String'，必填'int'
我有搜索網站，但沒有得到任何東西來幫助我解決我的問題。 我是一個android的新手，並開始了一個我無法完成的項目。使用過Android Studio 2.3 應用程序的名稱「匹配追蹤」
確定這裏
它走的 例如我的應用程序允許您跟蹤匹配「橄欖球」我現在想應用到自動點添加到領先榜如果一個球隊有4次或更多的嘗試，那就是我卡住的地方！

現在不工作的部分是本
int bpts = factsDbAdapter.countTriesWithMatchID(factsDbAdapter.KEY_MATCHID, factsDbAdapter.KEY_TYPE, factsDbAdapter.KEY_TEAM);
if (bpts<3)
任何人都可以幫助我或引導我在正確的方向請更好地描述下面的代碼
switch (status) {
case WIN: {// Team won the match.
int totalWins = teamAdapter.getColumnValueForTeamInt(teamAdapter.KEY_WINS, team);
int totalPoints = teamAdapter.getColumnValueForTeamInt(teamAdapter.KEY_TOTALPOINTS, team);
int totalBonusPoints = teamAdapter.getColumnValueForTeamInt(teamAdapter.KEY_BONUSPOINTS, team);
teamAdapter.updateSingleColumn(team, teamAdapter.KEY_WINS, totalWins + 1);
int bpts = factsDbAdapter.countTriesWithMatchID(factsDbAdapter.KEY_MATCHID, factsDbAdapter.KEY_TYPE, factsDbAdapter.KEY_TEAM);
if (bpts<3) {
teamAdapter.updateSingleColumn(team, teamAdapter.KEY_BONUSPOINTS, totalBonusPoints + 1);
teamAdapter.updateSingleColumn(team, teamAdapter.KEY_TOTALPOINTS, totalPoints + 5);
}
else
{
teamAdapter.updateSingleColumn(team, teamAdapter.KEY_TOTALPOINTS, totalPoints + 4);
}
break;

預先感謝您
請顯示'factsDbAdapter.KEY_MATCHID'的定義和值。確保它是一個'int'而不是'String'。 – john16384
@ Mark Rotteveel您好factDbAdapter.KEY_MATCHID的值應該是1到100之間的任何值，具體取決於記錄的匹配數量。 – Morne
是的，但它是一個'字符串？因爲預計有'int'，Java不會自動轉換這些類型。請顯示該行代碼。 – john16384
