ToolBar使用记录

一.ToolBar 1.首先在xml声明

<android.support.v7.widget.Toolbar android:id="@+id/toolbar_news_details" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize"//安照actionBar的高度 app:popupTheme="@style/ToolbarPopupTheme" //Menu的主题 app:layout_collapseMode="pin" // 是否隐藏导航箭头 > <TextView android:id="@+id/title_news_datails" android:layout_width="wrap_content" android:layout_height="wrap_content"/>

2.在res新建menu文件夹添加如下xml:

<?xml version="1.0" encoding="utf-8"?> <menu xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto"> <item android:id="@+id/open_on_browser" android:icon="@drawable/ic_launcher" android:title="在浏览器中打开" app:showAsAction="never"/> <item android:id="@+id/share" android:icon="@drawable/ic_launcher" android:title="分享" app:showAsAction="never"/> <item android:id="@+id/refresh" android:icon="@drawable/ic_refresh_white_18dp" android:title="刷新" app:showAsAction="always"/> <item android:id="@+id/copy_url" android:icon="@drawable/ic_launcher" android:title="复制网址" app:showAsAction="never"/> </menu> //关于shownAsAction可以自行百度

3.代码中实现:

private void initToolbar() { mTitleNewsDatails.setText(mTitle); mToolbarNewsDetails.inflateMenu(R.menu.news_details_menu); mToolbarNewsDetails.setNavigationIcon(R.drawable.ic); mToolbarNewsDetails.setNavigationOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { finish(); } }); mToolbarNewsDetails.setOnMenuItemClickListener(new Toolbar.OnMenuItemClickListener() { @Override public boolean onMenuItemClick(MenuItem item) { int itemId = item.getItemId(); switch (itemId) { case R.id.open_on_browser: break; case R.id.share: break; case R.id.refresh: break; case R.id.copy_url: break; default: break; } return false; } });

二.可以折叠的ToolBar

//只改变xml即可: <?xml version="1.0" encoding="utf-8"?> <android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:id="@+id/activity_news_details" android:layout_width="match_parent" android:layout_height="match_parent" > <android.support.design.widget.AppBarLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar"> <android.support.design.widget.CollapsingToolbarLayout android:id="@+id/toolbarlayout" android:layout_width="match_parent" android:layout_height="wrap_content" app:contentScrim="?attr/colorPrimary" app:expandedTitleMarginEnd="64dp" app:expandedTitleMarginStart="48dp" app:layout_scrollFlags="scroll|enterAlways" > <!--app:layout_scrollFlags="scroll|exitUntilCollapsed"--> <android.support.v7.widget.Toolbar android:id="@+id/toolbar_news_details" android:layout_width="match_parent" android:layout_height="?attr/actionBarSize" app:popupTheme="@style/ToolbarPopupTheme" app:layout_collapseMode="pin"> <TextView android:id="@+id/title_news_datails" android:layout_width="wrap_content" android:layout_height="wrap_content"/> </android.support.v7.widget.Toolbar> </android.support.design.widget.CollapsingToolbarLayout> </android.support.design.widget.AppBarLayout> </android.support.design.widget.CoordinatorLayout>
