1   ImageSwitcher实现的功能 和实际运行的效果图示意

ImageSwitcher类提供了图片切换功能，通过第三方的操作，设置当前ImageSwitcher显示的图片，同时设置图片变换的动画。

 

2  如何使用ImageSwitcher控件

 

2.1 配置页面文件

     <imageswitcher< p="">

            android:id="@+id/imageSwitcher1"

            android:layout_width="fill_parent"

            android:layout_height="fill_parent"

            android:layout_alignLeft="@+id/textView1"

            android:layout_above="@id/adLayout"

            android:layout_below="@id/topText"

            android:layout_centerVertical="true" >

       

 

3  初始化ImageSwitcher控件

 初始化ViewPager控件的适配器

 

imageSwitcher1 = (ImageSwitcher) findViewById(R.id.imageSwitcher1);

        imageSwitcher1.setFactory(this);

        imageSwitcher1.setInAnimation(AnimationUtils.loadAnimation(this,

                android.R.anim.fade_in));

        imageSwitcher1.setOutAnimation(AnimationUtils.loadAnimation(this,

                android.R.anim.fade_out));

   

      imageSwitcher1.setImageResource(R.drawable.girl2);

 

4 根据界面滑动的方向切换图片

OnTouchListener touchlistener = new OnTouchListener() { 

          

        @Override 

        public boolean onTouch(View v, MotionEvent event) { 

            if (event.getAction() == MotionEvent.ACTION_DOWN) { 

                downX = (int) event.getX();

                return true; 

            } else if (event.getAction() == MotionEvent.ACTION_UP) { 

                upX = (int) event.getX();

                if (upX - downX > 100) {

  imageSwitcher1.setInAnimation(AnimationUtils.loadAnimation(ShowPhotoActivity.this,

                            android.R.anim.slide_in_left));

                    imageSwitcher1.setOutAnimation(AnimationUtils.loadAnimation(ShowPhotoActivity.this,

                            android.R.anim.slide_out_right));

                    imageSwitcher1.setImageResource(R.drawable.girl1);

                   

                } else if (downX - upX > 100)//                { 

               

                    imageSwitcher1.setInAnimation(AnimationUtils.loadAnimation(ShowPhotoActivity.this,

                            android.R.anim.slide_in_left));

                    imageSwitcher1.setOutAnimation(AnimationUtils.loadAnimation(ShowPhotoActivity.this,

                            android.R.anim.slide_out_right));

                    imageSwitcher1.setImageResource(R.drawable.girl2);

                   

                } 

                return true; 

            } 

            return false; 

        } 

    };
