setOnActionExpandListener()監(jiān)聽(tīng)展開(kāi)收縮事件
android:actionViewLayout
引入布局用于操作窗口王污，效果類似于android:actionViewClass-
android:actionProviderClass<item android:id="@+id/action_share" android:title="share" app:showAsAction="always" app:actionProviderClass="android.support.v7.widget.ShareActionProvider" />顯示布局及可以監(jiān)聽(tīng)相關(guān)事件
@Override public boolean onCreateOptionsMenu(Menu menu) { // Inflate the menu; this adds items to the action bar if it is present. getMenuInflater().inflate(R.menu.menu_main, menu); MenuItem shareItem = menu.findItem(R.id.action_share); if (searchItem != null) { mShareActionProvider = (ShareActionProvider) MenuItemCompat.getActionProvider(shareItem); if (!setShareIntent()){ menu.removeItem(R.id.action_share); //沒(méi)有第三方可以分享，可以自定義 //如果一個(gè)應(yīng)用程序需要接受Share Intent發(fā)送的共享數(shù)據(jù)棒妨， // 那么需要在該應(yīng)用程序的Manifest.xml文件中定義<intent-filter/>元素 //android.intent.action.SEND， // 指明應(yīng)用組件想要接受的intent } } return super.onCreateOptionsMenu(menu); }// Call to update the share intent private boolean setShareIntent() { if (mShareActionProvider != null) { Intent shareIntent = new Intent(Intent.ACTION_SEND); shareIntent.setType("text/plain"); shareIntent.putExtra(Intent.EXTRA_TEXT, "share content");//EXTRA_STREAM PackageManager pm = getPackageManager(); //檢查手機(jī)上是否存在可以處理這個(gè)動(dòng)作的應(yīng)用 List<ResolveInfo> infoList = pm.queryIntentActivities(shareIntent, 0); if (!infoList.isEmpty()) { mShareActionProvider.setShareIntent(shareIntent); return true; } return false; } return false; }這種會(huì)記錄偏好含长，可通過(guò)
setShareHistoryFileName()設(shè)置記錄的xml文件名設(shè)置
setOnShareTargetSelectedListener監(jiān)聽(tīng)條目點(diǎn)擊事件可繼承
support包下ActionProvider自定義實(shí)現(xiàn)
android.support.design.R.dimen.abc_action_bar_default_height_material
關(guān)于overflow menu在高版本不顯示icon
安卓4.0之前會(huì)顯示icon券腔，高版本中不會(huì)顯示，可以通過(guò)反射去設(shè)置icon的顯示
private void setIconEnable(Menu menu, boolean enable) {
if (menu != null) {
try {
Class clazz = menu.getClass();
if (clazz.getSimpleName().equals("MenuBuilder")) {
Method m = clazz.getDeclaredMethod("setOptionalIconsVisible", Boolean.TYPE);
m.setAccessible(true);
//MenuBuilder實(shí)現(xiàn)Menu接口拘泞，創(chuàng)建菜單時(shí)纷纫，傳進(jìn)來(lái)的menu其實(shí)就是MenuBuilder對(duì)象
m.invoke(menu, enable);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
/**
* android 4.0以后使用AppCompatActivity必須在該方法中調(diào)用setIconEnable（），
* 隱藏的menuitem的icon才會(huì)顯示
* android 4.0以后其他的activity可以再onPrepreOptionMenu()中調(diào)用
* android 4.0以前可以正常顯示overflow中的menuitem的icon
* @param view

手機(jī)實(shí)體菜單按鍵導(dǎo)致actionbar上的三個(gè)點(diǎn)圖標(biāo)不顯示

可以通過(guò)自定義toolbar中布局實(shí)現(xiàn)理想效果
ActionBar actionBar = getSupportActionBar();
//設(shè)置自定義actionbar的view
actionBar.setCustomView(R.layout.action_bar_layout);
//設(shè)置展示的options為DISPLAY_SHOW_CUSTOM
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
//設(shè)置showCustom為true
actionBar.setDisplayShowCustomEnabled(true);
上下文菜單 ContextMenu
浮動(dòng)上下文菜單
registerForContextMenu(View view)注冊(cè)于上下文菜單關(guān)聯(lián)的View-
Activity 或 Fragment實(shí)現(xiàn)
registerForContextMenu()诗鸭，當(dāng)關(guān)聯(lián)的View收到長(zhǎng)按事件之后染簇，會(huì)響應(yīng)該方法。@Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenuInfo menuInfo) { super.onCreateContextMenu(menu, v, menuInfo); MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.context_menu, menu); } -
事件監(jiān)聽(tīng)
@Override public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); switch (item.getItemId()) { //TODO default: return super.onContextItemSelected(item); } }
為單個(gè)視圖啟用上下文操作模式
- 實(shí)現(xiàn) ActionMode.Callback 接口强岸。在其回調(diào)方法中锻弓，您既可以為上下文操作欄指定操作，又可以響應(yīng)操作項(xiàng)目的點(diǎn)擊事件蝌箍，還可以處理操作模式的其他生命周期事件
- 當(dāng)需要顯示操作欄時(shí)青灼，調(diào)用
activity的startActionMode()方法
彈出菜單 PopupMenu
public void showPopup(View v) {
PopupMenu popup = new PopupMenu(this, v);
MenuInflater inflater = popup.getMenuInflater();
inflater.inflate(R.menu.actions, popup.getMenu());
popup.show();
}
通過(guò)setOnMenuItemclickListener()設(shè)置監(jiān)聽(tīng)
基于 Intent 的菜單項(xiàng)
通過(guò)intent_filter定義刪選規(guī)則 CATEGORY_ALTERNATIVE 和 CATEGORY_SELECTED_ALTERNATIVE
調(diào)用Menu.addIntentOptions()來(lái)添加應(yīng)用列表

final ListPopupWindow popup = new ListPopupWindow(mContext);
List<String> list = new ArrayList<>();
list.add("不喜歡");
list.add("舉報(bào)");
