我有一个 fragment ,我想从中加载操作栏中的自定义 View ,所以我执行以下操作。
在表单 Activity 中:
public class FormActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_form);
try {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction fragmentTransaction = fragmentManager
.beginTransaction();
fragmentTransaction.replace(R.id.content_frame, new FormFragment()).addToBackStack(null).commit();
} catch (Exception e) {
e.printStackTrace();
}
}
在 fragment 本身中:
public class FormFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View actionBarButtons = inflater.inflate(R.layout.form_custom_actionbar,
new LinearLayout(getActivity()), false);
View cancelActionView = actionBarButtons.findViewById(R.id.action_cancel);
cancelActionView.setOnClickListener(this);
View doneActionView = actionBarButtons.findViewById(R.id.action_done);
doneActionView.setOnClickListener(this);
ActionBar ab = ((ActionBarActivity) getActivity()).getSupportActionBar();
ab.setCustomView(actionBarButtons);
return inflater.inflate(R.layout.fragment_form, null);
}
...
CustomActionBar 资源布局:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:divider="?android:attr/dividerVertical"
android:dividerPadding="12dip"
android:showDividers="middle">
<!-- id must match corresponding menu item id -->
<LinearLayout
android:id="@+id/action_cancel"
style="@style/FormCustomActionButton">
<ImageView
android:src="@drawable/ic_action_remove"
style="@style/FormCustomActionButtonImage" />
<TextView
android:text="@string/discard_label"
style="@style/FormCustomActionButtonText"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
<!-- id must match corresponding menu item id -->
<LinearLayout
android:id="@+id/action_done"
style="@style/FormCustomActionButton">
<ImageView
android:src="@drawable/abc_ic_cab_done_holo_light"
style="@style/FormCustomActionButtonImage" />
<TextView
android:text="@string/save_label"
style="@style/FormCustomActionButtonText"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
</LinearLayout>
fragment 加载正常,但我没有在顶部获得自定义操作栏按钮。我错过了什么?
