我不斷收到錯誤 incompatible type , Required android.widget.spinner, found int

Question

我想要將 onItemSelected 的結果從字符串數組存儲到 int 並將其存儲在數據庫中的方法

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {     

String selection = (String)parent.getItemAtPosition(position);

if (!TextUtils.isEmpty(selection)){
    if (selection.equals("Critical")){
        mySpinner = storeEntry.PRIORITY_CRITICAL;
    }else if (selection.equals("Important")){
        mySpinner = storeEntry.PRIORITY_IMPORTANT;
    }else if (selection.equals("Casual")){
        mySpinner = storeEntry.PRIORITY_CASUAL;
    }else {
        mySpinner = storeEntry.PRIORITY_NORMAL;
    }
 }
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
    mySpinner = storeEntry.PRIORITY_NORMAL;

}

我想克服那個錯誤

Answer 1

您只是將 View 的名稱與變量混淆了。

mySpinner是您的視圖。 您可能創建了另一個變量來存儲當前所選項目的 id。 使用該整數而不是mySpinner 。

它看起來像這樣：

int mySpinnerSelection = storeEntry.PRIORITY_NORMAL; //Assuming priority is integer

public void onItemSelected(AdapterView<?> parent, View view, int position, long id) {     

String selection = (String)parent.getItemAtPosition(position);

if (!TextUtils.isEmpty(selection)){
    if (selection.equals("Critical")){
        mySpinnerSelection = storeEntry.PRIORITY_CRITICAL;
    }else if (selection.equals("Important")){
        mySpinnerSelection = storeEntry.PRIORITY_IMPORTANT;
    }else if (selection.equals("Casual")){
        mySpinnerSelection = storeEntry.PRIORITY_CASUAL;
    }else {
        mySpinnerSelection = storeEntry.PRIORITY_NORMAL;
    }
 }
}
@Override
public void onNothingSelected(AdapterView<?> parent) {
    mySpinnerSelection = storeEntry.PRIORITY_NORMAL;

}
