android:showAsAction-
ifRoom: Only place this item in the app bar if there is room for it -
never: overflow menu -
withText: only textandroid:title -
always: on the bar -

android:actionViewClass<item android:id="@+id/action_search" android:title="@string/action_search" android:icon="@drawable/ic_search" app:showAsAction="ifRoom|collapseActionView" app:actionViewClass="android.support.v7.widget.SearchView" />通过
setOnActionExpandListener()监听展开收缩事件
android:actionViewLayout
引入布局用于操作窗口，效果类似于android:actionViewClass-
android:actionProviderClass<item android:id="@+id/action_share" android:title="share" app:showAsAction="always" app:actionProviderClass="android.support.v7.widget.ShareActionProvider" />显示布局及可以监听相关事件
@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); //没有第三方可以分享，可以自定义 //如果一个应用程序需要接受Share Intent发送的共享数据， // 那么需要在该应用程序的Manifest.xml文件中定义<intent-filter/>元素 //android.intent.action.SEND， // 指明应用组件想要接受的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(); //检查手机上是否存在可以处理这个动作的应用 List<ResolveInfo> infoList = pm.queryIntentActivities(shareIntent, 0); if (!infoList.isEmpty()) { mShareActionProvider.setShareIntent(shareIntent); return true; } return false; } return false; }这种会记录偏好，可通过
setShareHistoryFileName()设置记录的xml文件名设置
setOnShareTargetSelectedListener监听条目点击事件可继承
support包下ActionProvider自定义实现
android.support.design.R.dimen.abc_action_bar_default_height_material
关于overflow menu在高版本不显示icon
安卓4.0之前会显示icon，高版本中不会显示，可以通过反射去设置icon的显示
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实现Menu接口，创建菜单时，传进来的menu其实就是MenuBuilder对象
m.invoke(menu, enable);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
/**
* android 4.0以后使用AppCompatActivity必须在该方法中调用setIconEnable（），
* 隐藏的menuitem的icon才会显示
* android 4.0以后其他的activity可以再onPrepreOptionMenu()中调用
* android 4.0以前可以正常显示overflow中的menuitem的icon
* @param view
* @param menu
* @return
*/
@Override
protected boolean onPrepareOptionsPanel(View view, Menu menu) {
setIconEnable(menu, true);//让在overflow中的menuitem的icon显示
return super.onPrepareOptionsPanel(view, menu);
}
手机实体菜单按键导致actionbar上的三个点图标不显示
/**
* 通过反射，设置实体menu键可用与否
* 该方法在onCreate（）中调用
* @param enable false:实体键不可用，会在actionbar上显示小点
* true：可用，点击menu实体键才会显示menuitem
*/
public void setHasPermanentMenuKey(boolean enable){
try {
ViewConfiguration mconfig = ViewConfiguration.get(this);
Field menuKeyField = ViewConfiguration.class.getDeclaredField("sHasPermanentMenuKey");
if(menuKeyField != null) {
menuKeyField.setAccessible(true);
menuKeyField.setBoolean(mconfig, enable);
}
} catch (Exception ex) {
}
}
可以通过自定义toolbar中布局实现理想效果
ActionBar actionBar = getSupportActionBar();
//设置自定义actionbar的view
actionBar.setCustomView(R.layout.action_bar_layout);
//设置展示的options为DISPLAY_SHOW_CUSTOM
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM);
//设置showCustom为true
actionBar.setDisplayShowCustomEnabled(true);
上下文菜单 ContextMenu
浮动上下文菜单
registerForContextMenu(View view)注册于上下文菜单关联的View-
Activity 或 Fragment实现
registerForContextMenu()，当关联的View收到长按事件之后，会响应该方法。@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); } -
事件监听
@Override public boolean onContextItemSelected(MenuItem item) { AdapterContextMenuInfo info = (AdapterContextMenuInfo) item.getMenuInfo(); switch (item.getItemId()) { //TODO default: return super.onContextItemSelected(item); } }
为单个视图启用上下文操作模式
- 实现 ActionMode.Callback 接口。在其回调方法中，您既可以为上下文操作栏指定操作，又可以响应操作项目的点击事件，还可以处理操作模式的其他生命周期事件
- 当需要显示操作栏时，调用
activity的startActionMode()方法
弹出菜单 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();
}
通过setOnMenuItemclickListener()设置监听
基于 Intent 的菜单项
通过intent_filter定义删选规则 CATEGORY_ALTERNATIVE 和 CATEGORY_SELECTED_ALTERNATIVE
调用Menu.addIntentOptions()来添加应用列表
ListPopupMenu
final ListPopupWindow popup = new ListPopupWindow(mContext);
List<String> list = new ArrayList<>();
list.add("不喜欢");
list.add("举报");
popup.setBackgroundDrawable(new ColorDrawable(Color.WHITE));
popup.setAdapter(new ArrayAdapter<>(mContext, R.layout.biz_elevator_layout_note_popup_item, list));
popup.setWidth( mContext.getResources().getDimensionPixelSize(R.dimen.width40));
popup.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
popup.setAnchorView(mUserLayout);
popup.setModal(true);
popup.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> parent, View view,
int position, long id) {
switch (position) {
case 0:
break;
case 1:
break;
}
popup.dismiss();
}
});
popup.setHorizontalOffset(-40);
popup.setDropDownGravity(Gravity.END);
popup.show();
PopupWindow
final PopupWindow popupWindow = new PopupWindow(mContext);
View inflate = LayoutInflater.from(mContext).inflate(R.layout.biz_elevator_layout_note_item_popup, null);
View tvDislike = inflate.findViewById(R.id.popup_dislike);
View tvReport = inflate.findViewById(R.id.popup_report);
tvDislike.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mCallback != null) {
mCallback.onDisLikeClicked(v, mPosition);
}
popupWindow.dismiss();
}
});
tvReport.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
if (mCallback != null) {
mCallback.onReportClicked(v, mPosition);
}
popupWindow.dismiss();
}
});
popupWindow.setContentView(inflate);
popupWindow.setWidth(ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setHeight(ViewGroup.LayoutParams.WRAP_CONTENT);
popupWindow.setBackgroundDrawable(new ColorDrawable(Color.WHITE));
// this setting can intercept the touch event when popupWindow opened
popupWindow.setFocusable(true);
popupWindow.setTouchable(true);
popupWindow.setOutsideTouchable(true);
PopupWindowCompat.showAsDropDown(popupWindow, v, -50, 10, Gravity.LEFT);
