時，我一直在尋找一個國家印尼，英格蘭和意大利的關鍵詞「我」。當我選擇印度尼西亞，進入印度尼西亞活動，但是當我選擇inggris時爲什麼進入馬來西亞活動。 如何進入選定的活動？點擊監聽器有什麼問題？幫助我

Answer 1

'位置'是來自lv對象，因此您的過濾列表，而不是您的原始字符串列表。因此，當您選擇「inggris」時，重新設置的位置是1並開始馬來西亞活動。請嘗試：

public void onItemClick(AdapterView<?> arg0, View view, int position, long arg3){ 
LinearLayout tmpll = (LinearLayout) view; 
TextView tmptv = (TextView) tmpll.findViewById(R.id.negara_name); 
pos = negara.indexOf(tmptv.getText()); 

並將其他「位置」更改爲「pos」。
