用法

材質選單Drawable

將其用作Toolbar列中的獨立繪圖：

 private MaterialMenuDrawable materialMenu ;

protected void onCreate ( Bundle savedInstanceState ) {
    super . onCreate ( savedInstanceState );
    setContentView ( R . layout . toolbar );
    Toolbar toolbar = ( Toolbar ) findViewById ( R . id . toolbar );
    setSupportActionBar ( toolbar );
    toolbar . setNavigationOnClickListener ( new View . OnClickListener () {
        @ Override public void onClick ( View v ) {
        // Handle your drawable state here
        materialMenu . animateState ( newState );
      }
    });
    materialMenu = new MaterialMenuDrawable ( this , Color . WHITE , Stroke . THIN );
    toolbar . setNavigationIcon ( materialMenu );
}

材質選單視圖

一個普通的舊View ，用於繪製圖標並提供 API 來操作其狀態。您可以將其嵌入到任何佈局中，包括Toolbar 。

也可以透過 xml 屬性進行自訂：

app:mm_color="color"               // Color of drawable
app:mm_visible="boolean"           // Visible
app:mm_transformDuration="integer" // Transformation animation duration
app:mm_scale="integer"             // Scale factor of drawable
app:mm_strokeWidth="integer"       // Stroke width of icons (can only be 1, 2 or 3)
app:mm_rtlEnabled="boolean"        // Enabled RTL layout support (flips all drawables)
app:mm_iconState="enum"            // Set the intial state of the drawable (burger, arrow, x or check)

應用程式介面

有四種圖標狀態：

 BURGER , ARROW , X , CHECK

改變可繪製狀態

 MaterialMenu . animateIconState ( IconState state )

變更可繪製狀態而不使用動畫

 MaterialMenu . setIconState ( IconState state )

若要手動為可繪製物件設定動畫（即在導覽抽屜投影片上）：

 MaterialMenu . setTransformationOffset ( AnimationState state , float value )

隱藏或顯示可繪製物件：

 MaterialMenu . setVisible ( boolean visible )

其中AnimationState是BURGER_ARROW, BURGER_X, ARROW_X, ARROW_CHECK, BURGER_CHECK, X_CHECK之一， value介於0和2之間

注意：圖示狀態由目前偏移值決定。確保對向前動畫使用0到1之間的offset ，對向後動畫使用1和2之間的偏移量，以便在活動重新建立時正確儲存圖示狀態。

NavigationDrawer滑動交互

如上所述，在 ActionBar 中實作MaterialMenu並新增自訂DrawerListener ：

 private DrawerLayout drawerLayout ;
private boolean isDrawerOpened ;
private MaterialMenuDrawable materialMenu ;

@ Override
protected void onCreate ( Bundle savedInstanceState ) {
    super . onCreate ( savedInstanceState );
    toolbar = ( Toolbar ) findViewById ( R . id . toolbar );
    setSupportActionBar ( toolbar );
    materialMenu = new MaterialMenuDrawable ( this , Color . WHITE , Stroke . THIN );
    toolbar . setNavigationIcon ( materialMenu );

    drawerLayout = ( DrawerLayout ) findViewById ( R . id . drawer_layout );
    drawerLayout . setDrawerListener ( new DrawerLayout . SimpleDrawerListener () {
        @ Override
        public void onDrawerSlide ( View drawerView , float slideOffset ) {
            materialMenu . setTransformationOffset (
                MaterialMenuDrawable . AnimationState . BURGER_ARROW ,
                isDrawerOpened ? 2 - slideOffset : slideOffset
            );
        }

        @ Override
        public void onDrawerOpened ( View drawerView ) {
            isDrawerOpened = true ;
        }

        @ Override
        public void onDrawerClosed ( View drawerView ) {
            isDrawerOpened = false ;
        }
        
        @ Override
        public void onDrawerStateChanged ( int newState ) {
            if ( newState == DrawerLayout . STATE_IDLE ) {
                if ( isDrawerOpened ) {
                   menu . setIconState ( MaterialMenuDrawable . IconState . ARROW );
                } else {
                   menu . setIconState ( MaterialMenuDrawable . IconState . BURGER );
                }
            }
        }
    });
}
