单击时如何更改SlidingDrawer句柄上的图标

Question

我试图打开滑动抽屉时试图改变手柄上的图标.当我从视图中提取句柄并设置onclicklistener或ontouchlistener时,似乎永远不会获得trigget.

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);

    SlidingDrawer drawer = (SlidingDrawer)findViewById(R.id.drawer_landscape);

    ImageView handle = (ImageView)findViewById(R.id.handle_l);
    handle.setFocusable(true);

    handle.setOnClickListener(new OnClickListener(){


        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub
            Log.i("test","onClick");
        }

    });


}

还有我的XML

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:id="@+id/base_frame_layout"
     android:layout_gravity="bottom"
     >        
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        >
        <TextView  
            android:layout_width="fill_parent" 
            android:layout_height="wrap_content" 
            android:text="@string/hello"
            />
    </LinearLayout>

        <SlidingDrawer
             android:id="@+id/drawer_landscape"
             android:layout_width="wrap_content"
             android:layout_height="wrap_content"
             android:handle="@+id/handle_l"
             android:content="@+id/content"
             android:orientation="vertical"
             android:visibility="visible"
        >

            <ImageView
                android:id="@+id/handle_l"
                android:layout_height="50px"
                android:layout_width="64px"
                android:padding="0px"
                android:src="@drawable/icon"
            />

            <TextView
                android:id="@+id/content" 
                android:text="content" 
                android:layout_height="50px"
                android:layout_width="64px"
            />                  

         </SlidingDrawer>       

</FrameLayout>

我希望这段代码应该记录"onClick"消息,但事实并非如此.

有任何想法吗？

我发现它很简单......我只需要在抽屉上设置setOnDrawerScrollListener.

而不是实现onScrollEnded和onScrollStarted上的2个方法.

    mSlidingDrawer.setOnDrawerScrollListener(new OnDrawerScrollListener(){

        @Override
        public void onScrollEnded() {
            // TODO Auto-generated method stub
            Log.i("ddd","onScrollEnded slider");
            slider_animation.reverseTransition(HANDLE_ANIMATION_SPEED);
        }

        @Override
        public void onScrollStarted() {
            // TODO Auto-generated method stub
            Log.i("ddd","onScrollStarted slider");
            slider_animation.startTransition(HANDLE_ANIMATION_SPEED);
        }

});

我宁愿在手柄上使用动画而不是改变图像因为闪烁.
