  • Android: Toolbar、AppBarLayout

    ToolBar是google退出的一个应用程序动作条

    包括:

    • 设置导航栏图标
    • 设置应用程序Logo
    • 设置标题
    • 设置子标题
    • 添加各种自定义控件
    • 添加动作条菜单

    API:https://developer.android.com/reference/android/support/v7/widget/Toolbar.html

    1. 兼容处理,使用v7兼容包,build.gradle配置

        compile 'com.android.support:appcompat-v7:24.0.0'
    View Code

    2. 隐藏默认的动作条,可以使用NoActionBar的theme,也可以在activity使用代码

    3. 布局文件中可以支持出了动作条菜单actionmenu外的所有功能,

        但是一定要添加自定义命名空间,指向 http://schemas.android.com/apk/res-auto

    <?xml version="1.0" encoding="utf-8"?>
    <android.support.design.widget.AppBarLayout
        xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:theme="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    
        <android.support.v7.widget.Toolbar
            android:id="@+id/toolBar"
            android:layout_height="match_parent"
            android:layout_width="match_parent"
            android:background="?attr/colorPrimary"
            app:popupTheme="@style/ThemeOverlay.AppCompat.Light"
            app:layout_scrollFlags="scroll|enterAlways"
            app:navigationIcon="@mipmap/ic_back"
            app:logo="@mipmap/ic_launcher"
            app:title="@string/app_name"
            app:subtitle="@string/home_title"
            app:subtitleTextColor="@color/bt_accent"
            >
    
    
            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:text="TestCustomView" />
    
        </android.support.v7.widget.Toolbar>
    
    </android.support.design.widget.AppBarLayout>
    View Code

    4. 通过代码实现Toolbar的创建及menu事件监听

     activity

    package com.media.customplayer;
    
    import android.support.design.widget.NavigationView;
    import android.support.design.widget.NavigationView.OnNavigationItemSelectedListener;
    import android.support.v4.view.GravityCompat;
    import android.support.v4.widget.DrawerLayout;
    import android.support.v4.widget.DrawerLayout.DrawerListener;
    import android.support.v7.app.AppCompatActivity;
    import android.os.Bundle;
    import android.support.v7.widget.Toolbar;
    import android.support.v7.widget.Toolbar.OnMenuItemClickListener;
    import android.util.Log;
    import android.view.MenuItem;
    import android.view.View;
    
    public class PlayerActivity extends AppCompatActivity {
    
        private final String TAG = "PlayerActivity";
        private DrawerLayout mPlayerDrawer;
        private NavigationView mNaviView;
        private Toolbar mToolbar;
    
        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_player);
    
            mPlayerDrawer = (DrawerLayout) findViewById(R.id.palyer_drawer_layout);
            mPlayerDrawer.addDrawerListener(drawerListener);
    
            mNaviView = (NavigationView) findViewById(R.id.navi_view);
            mNaviView.setNavigationItemSelectedListener(naviItemSelectedListener);
    
            updateToolbar();
        }
    
        private DrawerListener drawerListener = new DrawerLayout.DrawerListener() {
            @Override
            public void onDrawerSlide(View drawerView, float slideOffset) {
                Log.v(TAG, "onDrawerSlide: slideOffset = " + slideOffset);
            }
    
            @Override
            public void onDrawerOpened(View drawerView) {
                Log.v(TAG, "onDrawerOpened");
            }
    
            @Override
            public void onDrawerClosed(View drawerView) {
                Log.v(TAG, "onDrawerClosed");
            }
    
            @Override
            public void onDrawerStateChanged(int newState) {
                Log.v(TAG, "onDrawerStateChanged: newState = " + newState);
            }
        };
    
        private OnNavigationItemSelectedListener naviItemSelectedListener = new OnNavigationItemSelectedListener() {
            @Override
            public boolean onNavigationItemSelected(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.navi_all:
                        Log.v(TAG, "播放所有音乐");
                        break;
                    case R.id.navi_playlists:
                        Log.v(TAG, "播放音乐列表");
                        break;
                    default:
                        Log.v(TAG, "点击按钮: " + item.getItemId());
                }
    
                item.setChecked(true);
                mPlayerDrawer.closeDrawer(GravityCompat.START, true);
                return true;
            }
        };
    
        private OnMenuItemClickListener menuItemClickListener = new OnMenuItemClickListener() {
            @Override
            public boolean onMenuItemClick(MenuItem item) {
                switch (item.getItemId()) {
                    case R.id.navi_all:
                        Log.v(TAG, "播放所有音乐");
                        break;
                    case R.id.navi_playlists:
                        Log.v(TAG, "播放音乐列表");
                        break;
                    default:
                        Log.v(TAG, "点击按钮: " + item.getItemId());
                }
    
                item.setChecked(true);
                return true;
            }
        };
    
        private void updateToolbar() {
            mToolbar = (Toolbar) findViewById(R.id.player_toolbar);
    
            mToolbar.setNavigationIcon(R.mipmap.ic_back);
            mToolbar.setLogo(R.mipmap.ic_launcher);
            mToolbar.setTitle(R.string.app_name);
            mToolbar.setSubtitle(R.string.home_title);
    
            mToolbar.inflateMenu(R.menu.player_toolbar_menu);
            mToolbar.setOnMenuItemClickListener(menuItemClickListener);
        }
    
    }
    View Code

       menu layout

    <?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">
        <group android:checkableBehavior="single">
            <item
                android:id="@+id/navi_all"
                android:icon="@mipmap/ic_allmusic_black_24dp"
                android:title="@string/drawer_allmusic_title"
                app:showAsAction="ifRoom"/>
            <item
                android:id="@+id/navi_playlists"
                android:icon="@mipmap/ic_playlist_music_black_24dp"
                android:title="@string/drawer_playlists_title"
                android:checked="true" />
            <item
                android:id="@+id/navi_sub_item_bottom_1"
                android:icon="@mipmap/ic_allmusic_black_24dp"
                android:title="@string/drawer_sub_playlist_title" />
            <item
                android:id="@+id/navi_sub_item_bottom_2"
                android:icon="@mipmap/ic_allmusic_black_24dp"
                android:title="@string/drawer_sub_playlist_title" />
        </group>
    </menu>
    View Code

    5. 修改action menu的颜色

      style.xml

    <resources>
    
        <!-- Base application theme. -->
        <style name="PlayerTheme" parent="Theme.AppCompat.Light.NoActionBar">
            <item name="colorPrimary">#ffff5722</item>
            <item name="colorPrimaryDark">#ffbf360c</item>
            <item name="colorAccent">#ffff5722</item>
            <item name="alertDialogTheme">@style/Theme.AppCompat.Dialog.Alert</item>
        </style>
    
        <style name="PlayerTheme.ToolBar" parent="PlayerTheme">
            <item name="android:textColorPrimary">#00B8D4</item>
        </style>
    
    </resources>
    View Code

      activity

            mToolbar.setPopupTheme(R.style.PlayerTheme_ToolBar);
    View Code

      可以是布局文件

            app:popupTheme="@style/PlayerTheme.ToolBar"
    View Code

    AppBarLayout

    AppBarLayout是一个垂直方向的LinearLayout,是为MaterialDesign设计的AppBar(包括的view都会认为是appbar),支持手势滑动。
