我想問的是那爲什麼我的動作項目不會出現在我的ActionBar事件中，儘管我已經寫過android:showAsAction="ifRoom|withText"或android:showAsAction="always"我不知道爲什麼它的行爲如此。
哇這是偉大正確的代碼。但我希望圖標出現在actionBar而不是文本中 –
@Jiazzyuser文檔中的另一個引用如果菜單項同時提供標題和圖標 - 標題和圖標屬性 - 則操作項僅顯示圖標默認。如果要顯示文本標題，請將「withText」添加到showAsAction屬性中。例如：'
還注意到如果沒有足夠的空間它會出現在溢出菜單中 – Raghunandan
