slidingMenu的使用

第三方框架就是一个工具

关键点：继承1-SlidingFragmentActivity

2-侧滑的layout使用FrameLayout，并将菜单的fragment替换到这个layout的Fragment

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/llMain"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical" >
    <TextView android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Sliding Menu Left"/>

    <ListView android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:id="@+id/lvSlidingMenu"></ListView>
</FrameLayout>

住Activity的侧滑代码---public class MainActivity extends SlidingFragmentActivity 

// TODO Auto-generated method stub
		Fragment leftMenuFragment = new MenuLeftFragment();  
        setBehindContentView(R.layout.slidingmenu_left);  
        getSupportFragmentManager().beginTransaction()  
                .replace(R.id.llMain, leftMenuFragment).commit();  
        SlidingMenu slidngMenu = getSlidingMenu();  
        slidngMenu.setMode(SlidingMenu.LEFT);  
        // 设置触摸屏幕的模式  
        slidngMenu.setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN);  
        slidngMenu.setShadowWidthRes(R.dimen.slidingmenu_shadow_width);  
        slidngMenu.setShadowDrawable(R.drawable.sliding_menu_shadow);  
        // 设置滑动菜单视图的宽度  
        slidngMenu.setBehindOffsetRes(R.dimen.slidingmenu_offset);  
        // 设置渐入渐出效果的值  
        slidngMenu.setFadeDegree(0.35f);  

slidingmenu的一些动画缩放：

折叠动画
new CanvasTransformer() {
			@Override
			public void transformCanvas(Canvas canvas, float percentOpen) {
				canvas.scale(percentOpen, 1, 0, 0);
			}			
		}

放缩动画
new CanvasTransformer() {
			@Override
			public void transformCanvas(Canvas canvas, float percentOpen) {
				float scale = (float) (percentOpen*0.25 + 0.75);
				canvas.scale(scale, scale, canvas.getWidth()/2, canvas.getHeight()/2);
			}
		}

上升动画
private static Interpolator interp = new Interpolator() {
		@Override
		public float getInterpolation(float t) {
			t -= 1.0f;
			return t * t * t + 1.0f;
		}		
	};

new CanvasTransformer() {
			@Override
			public void transformCanvas(Canvas canvas, float percentOpen) {
				canvas.translate(0, canvas.getHeight()*(1-interp.getInterpolation(percentOpen)));
			}			
		}
