Android OS - Menu
Oldingi maqolalarda biz, ListView, EditText kabi komponentalar bilan ishlashni ko'rib chiqqan edik. Ushbu maqolada biz menu bilan ishlashni o'rganib chiqishga harakat qilamiz.
Menu — togrisi bunga qanday ta'rif berishni bilmadim, chunki menu ni biz juda ham ko'p joylarda eshitganmiz, ko'rganmiz, nimaligini yaxshi bilamiz.
Ushbu darsimizda menular bilan ishlashni o'rganib chiqamiz.
Yangi proyekt yaratamiz File ⇒ New ⇒ Android Project
menu.xml nomli fayl yaratamiz /res/menu/ papkasini ichida.
Agar sizda menu degan papka yo'q bo'lsa, values degan papkani ichiga yaratsangiz ham bo'ladi.
menu.xml faylni ichiga quyidagilarni kiritamiz:
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/menu_bookmark"
android:icon="@android:drawable/ic_menu_add"
android:title="Bookmark" />
<item android:id="@+id/menu_save"
android:icon="@android:drawable/ic_menu_save"
android:title="Save" />
<item android:id="@+id/menu_search"
android:icon="@android:drawable/ic_menu_search"
android:title="Search" />
<item android:id="@+id/menu_share"
android:icon="@android:drawable/ic_manu_share"
android:title="Share" />
<item android:id="@+id/menu_delete"
android:icon="@android:drawable/ic_menu_delete"
android:title="Delete" />
<item android:id="@+id/menu_preferences"
android:icon="@android:drawable/ic_menu_preferences"
android:title="Preferences" />
</menu>Endi nimaga bularni yozganimizni aytib o'tsak:
/*bu yerga parametrlar yoziladi */ yoki <item /*bu yerga parametrlar yoziladi */ /> — agar biz yangi menu yaratmoqchi bo'lsak ushbu tegidan foydalanamiz.
<item android:id="@+id/menu_bookmark"
android:icon="@android:drawable/ic_menu_add"
android:title="Bookmark" />android:id="@+id/menu_bookmark"android:icon="@android:drawable/ic_menu_add"android:title="Bookmark"Endi asosiy Activity classimizni {MenuActivity.java } ni ochamiz va quyidagilarni yozamiz.

menuInflater.inflate(R.menu.menu, menu); //Bu yerda menu.xml faylimiz turgan joyiga yo'lni ko'rsatamiz
return true;
}
//Bu yerda menular bosilganda nima ish bajarish kerakligini yozamiz
// Hozir biz faqat oddiygina habar chiqaramiz
@Override public boolean onOptionsItemSelected(MenuItem item) {
switch(item.getItemId()) {
case R.id.menu_bookmark:
Toast.makeText(MenuActivity.this, "Bookmark menusi bosildi", Toast.LENGTH_SHORT).show();
return true;

return true;
default:
return super.onOptionsItemSelected(item);
}
}
}Dasturni ishga tushirishimiz mumkin:
Menulardan birortasini tanlaganimizda quyidagicha natija chiqadi:
