Question

我使用的是appcompat 7而不是sherlockactionbar。现在我想在操作栏中添加更新计数器按钮，但在onCreateOptionsMenu函数中返回null getActionView。我的代码是：

MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.main, menu);
View count = menu.findItem(R.id.update).getActionView();
TextView notifCount = (TextView) count.findViewById(R.id.textOne);
if(mNotifCount<=0) notifCount.setVisibility(View.GONE);
notifCount.setText(String.valueOf(mNotifCount));
return super.onCreateOptionsMenu(menu);

我的menu.xml

<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
xmlns:app="http://schemas.android.com/apk/res-auto"
tools:context=".MainActivity">
<item android:id="@+id/action_example" android:title="@string/action_example"
    app:showAsAction="withText|ifRoom" />
<item android:id="@+id/action_settings" android:title="@string/action_settings"
    android:orderInCategory="100" app:showAsAction="never" />
<item
    android:title="update"
    android:id="@+id/update"
    android:actionLayout="@layout/feed_update_count"
    app:showAsAction="always|collapseActionView"
    android:orderInCategory="0" />

Answer 1

将android:actionLayout更改为app:actionLayout并使用MenuItemCompat.getActionView(menuItem...);

Answer 2

您可能需要使用MenuItemCompat来加载动作视图;

SearchView searchView = (SearchView) MenuItemCompat.getActionView(menu.findItem(R.id.action_search));

getActionView在appcompat 7 actionbar中返回null
