本文主要翻译android开发官网Training中关于ActionBar的几篇文章
<manifest ... >
<uses-sdk android:minSdkVersion="11" ... />
...
</manifest>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<!-- Search, should appear as action button -->
<item android:id="@+id/action_search"
android:icon="@drawable/ic_action_search"
android:title="@string/action_search"
android:showAsAction="ifRoom" />
<!-- Settings, should always be in the overflow -->
<item android:id="@+id/action_settings"
android:title="@string/action_settings"
android:showAsAction="never" />
</menu>此处，当action bar控件足够时，Search action按钮将直接呈现在action bar上，而如果Setting action会一直隐藏在overflow中。默认情况所有action都是在overflow中的，但是官方建议最好自己为各个item声明位置。@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu items for use in the action bar
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main_activity_actions, menu);
return super.onCreateOptionsMenu(menu);
}@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle presses on the action bar items
switch (item.getItemId()) {
case R.id.action_search:
openSearch();
return true;
case R.id.action_settings:
openSettings();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
