我有我的應用程序菜單上的側菜單這樣的代碼:改變菜單項標題從onCreateOptionsMenu
main.xml中
<menu xmlns:android="http://schemas.android.com/apk/res/android" >
<item
android:id="@+id/menu"
android:showAsAction="always"
android:title="@string/menu">
<menu>
<item android:id="@+id/edit"
android:title="@string/edit"
android:icon="@android:drawable/ic_menu_edit"/>
</menu>
</item>
</menu>
MainActive.java
boolean isEdit=false;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.history);
SharedPreferences sp = PreferenceManager.getDefaultSharedPreferences(getBaseContext());
isEdit=sp.getBoolean("isEdit", false);
}
public boolean onCreateOptionsMenu(android.view.Menu menu) {
android.view.MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
if(isEdit)
// change R.id.edit title to "test1"
return true;
}
如何我可以從if(isEdit)條件改變R.id.edit標題?!
謝謝it'a工作:) –
