我正在尝试在操作栏中添加操作项,但即使有很多空间,这些项始终会添加到溢出列表中。有什么建议可以解决这个问题吗?
这应该是这样的
main.xml
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/action_refresh"
android:icon="@drawable/ic_action_refresh"
android:showAsAction="ifRoom"
android:title="@string/action_refresh" />
<item
android:id="@+id/action_search"
android:icon="@drawable/ic_action_search"
android:showAsAction="ifRoom"
android:title="@string/action_search" />
<item
android:id="@+id/action_settings"
android:title="@string/action_settings"
app:showAsAction="never" />
</menu>
MainActivity.java
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
