[英]Android button only initiating method on second click
我有一個由按鈕制成的井字游戲板。 每個按鈕都鏈接到啟動邏輯的方法。 我遇到的問題是,當人類玩家(noughts)下他們的回合時,邏輯是跳過該回合,運行AI轉向,然后只回到人類玩家,這一次正在按預期工作。
在單擊時,按鈕是否有問題,應該調用setText
方法並將其標記為人類玩家的“ O”或AI的“ X”。 此后,該按鈕將設置為非活動狀態,並且跟蹤板的陣列也會更改。
我正在打印日志,從我所看到的來看,人類用戶的點擊是觸發移動AI的原因,而不是自動完成的。 但是我不能說為什么會這樣。 我認為我的邏輯存在缺陷,但是我無法找出問題所在。 編輯:第一次人為點擊就可以正常工作,這就是問題所在。

問題不屬於您的邏輯。 問題是如何實施。
當前,您已經有一個逐步的邏輯系統,其中的每個邏輯步驟都由receiveClick(View)方法觸發。 問題在於沒有自動觸發AI轉向。
您需要在playerClick(View)的末尾添加某種邏輯,以便如果玩家剛剛轉身,它將重新運行AI轉身的邏輯。
例:
public void playerClick(View view) {
Button B;
int boardSetIndex;
int boardSetValue;
if (view instanceof Button) {
B = (Button) view;
if ( noughtsTurn ) {
B.setText(player.noughtsPlayer());
} else {
B = aiPlayerPick();
System.out.println("AI picked: " + targetIndex);
B.setText(player.crossesPlayer());
}
board.set(boardSetIndex(), boardSetValue());
System.out.println("Board: " + board);
B.setEnabled(false);
//
if(setTurn(noughtsTurn) == false){
playNow(findViewByTag(randomButtonPick()))
}
//
}
}
在上面的示例中,缺少一些關鍵的東西,例如,檢查randomButtonPick()是否尚未被占用,以及setTurn(boolean)返回void而不是布爾值的事實。 您只需要某種方式來檢查玩家是否剛剛轉過彎,如果是,就讓AI轉彎。
好的,這是我解決此問題的最終解決方案。 我保持相同的邏輯,但是將人工和AI分離為單獨的方法,而AI仍然基於noughtsTurn
方法。
碼:
public void receiveClick(View view) {
String takeButton = String.valueOf(view.getTag());
buttonPressed = Integer.parseInt(takeButton);
humanPlayerTurn(view);
aiPlayerTurn(view);
}
public void humanPlayerTurn(View view) {
if (noughtsTurn) {
System.out.println("Player picked: " + buttonPressed);
playerClick(view);
}
}
public void aiPlayerTurn(View view) {
if (aiValidPick()) {
playerClick(view);
} else {
aiPlayerTurn(view);
}
}
