我昨天将我的应用从 ActionBarSherlock 转换为 ActionBarCompat。我遇到了一些问题，但没有太严重。
我有一些cmets：
要更新主题，我只需要将“Sherlock”覆盖为“AppCompat”。例如，我不是从@style/Theme.Sherlock.Light.DarkActionBar 继承，而是从@style/Theme.AppCompat.Light.DarkActionBar 继承。
对于操作项，只需这样更新：
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:yourapp="http://schemas.android.com/apk/res-auto" >
<item android:id="@+id/action_search"
android:icon="@drawable/ic_action_search"
android:title="@string/action_search"
yourapp:showAsAction="ifRoom" />
...
</menu>
并且在onCreateOptionsMenu中，使用普通的MenuItem，但是使用MenuItemCompat的静态方法来做ActionBar的事情。例如：MenuItemCompat.expandActionView(searchMenuItem);
如果你使用继承自 RoboSherlockActivity 的 RoboGuice，如果你只是复制它并更改为 ActionBarActivity，你会遇到麻烦。这是我的解决方案：
public class RoboActionBarActivity extends ActionBarActivity implements RoboContext {
protected EventManager eventManager;
protected HashMap<Key<?>, Object> scopedObjects = new HashMap<Key<?>, Object>();
@Inject
ContentViewListener ignored; // BUG find a better place to put this
@Override
protected void onCreate(Bundle savedInstanceState) {
final RoboInjector injector = RoboGuice.getInjector(this);
eventManager = injector.getInstance(EventManager.class);
injector.injectMembersWithoutViews(this);
super.onCreate(savedInstanceState);
eventManager.fire(new OnCreateEvent(savedInstanceState));
}
@Override
public void setContentView(int layoutResID) {
super.setContentView(layoutResID);
contentViewChanged();
}
@Override
public void setContentView(View view) {
super.setContentView(view);
contentViewChanged();
}
@Override
public void setContentView(View view, ViewGroup.LayoutParams params) {
super.setContentView(view, params);
contentViewChanged();
}
@Override
public void addContentView(View view, ViewGroup.LayoutParams params) {
super.addContentView(view, params);
contentViewChanged();
}
private void contentViewChanged() {
RoboGuice.getInjector(this).injectViewMembers(this);
eventManager.fire(new OnContentChangedEvent());
}
@Override
protected void onRestart() {
super.onRestart();
eventManager.fire(new OnRestartEvent());
}
@Override
protected void onStart() {
super.onStart();
eventManager.fire(new OnStartEvent());
}
@Override
protected void onResume() {
super.onResume();
eventManager.fire(new OnResumeEvent());
}
@Override
protected void onPause() {
super.onPause();
eventManager.fire(new OnPauseEvent());
}
@Override
protected void onNewIntent( Intent intent ) {
super.onNewIntent(intent);
eventManager.fire(new OnNewIntentEvent());
}
@Override
protected void onStop() {
try {
eventManager.fire(new OnStopEvent());
} finally {
super.onStop();
}
}
@Override
protected void onDestroy() {
try {
eventManager.fire(new OnDestroyEvent());
} finally {
try {
RoboGuice.destroyInjector(this);
} finally {
super.onDestroy();
}
}
}
@Override
public void onConfigurationChanged(Configuration newConfig) {
final Configuration currentConfig = getResources().getConfiguration();
super.onConfigurationChanged(newConfig);
eventManager.fire(new OnConfigurationChangedEvent(currentConfig, newConfig));
}
@Override
public void onContentChanged() {
super.onContentChanged();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
eventManager.fire(new OnActivityResultEvent(requestCode, resultCode, data));
}
@Override
public Map<Key<?>, Object> getScopedObjectMap() {
return scopedObjects;
}
}
现在，您使用 supportStartActionMode() 启动 ActionMode，并从库的包中导入 ActionMode。
要使用 SearchView，您需要执行以下操作：
<menu xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto">
<item
android:id="@+id/search"
app:actionViewClass="android.support.v7.widget.SearchView"
android:icon="@drawable/abc_ic_search"
app:showAsAction="always|collapseActionView"
android:title="@string/search"/>
</menu>
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.search_menu, menu);
searchMenuItem = menu.findItem(R.id.search);
searchView = (SearchView) MenuItemCompat.getActionView(searchMenuItem);
if (searchView != null) {
searchView.setIconifiedByDefault(false);
SearchView.OnQueryTextListener queryTextListener = new SearchView.OnQueryTextListener() {
public boolean onQueryTextChange(String newText) {
return true;
}
public boolean onQueryTextSubmit(String query) {
doSomething(query);
return true;
}
};
searchView.setOnQueryTextListener(queryTextListener);
}
return super.onCreateOptionsMenu(menu);
}
除了导入的包之外，其他的东西都没有修改。
