Android之ImageSwitcher

一. 简单示例

src

 

public class AndroidUIActivity extends Activity {

    // 当前显示的图片索引
    private int index;

    // 图片数组
    private int[] images = { R.drawable.image1, R.drawable.image2,
            R.drawable.image3, R.drawable.image4, R.drawable.image5 };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        // 全屏设置
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.main);

        // 得到ImageSwitcher对象
        final ImageSwitcher is = (ImageSwitcher) findViewById(R.id.imageSwitcher1);

        // 实现并设置工厂内部接口的makeView方法，用来显示视图。
        is.setFactory(new ViewFactory() {

            public View makeView() {
                return new ImageView(AndroidUIActivity.this);
            }
        });

        // 设置图片来源
        is.setImageResource(images[index]);

        // 设置点击监听器
        is.setOnClickListener(new View.OnClickListener() {

            public void onClick(View v) {
                // 点击会切换图片
                index++;
                if (index >= images.length) {
                    index = 0;
                }
                is.setImageResource(images[index]);
            }
        });

        // 设置切入动画
        is.setInAnimation(AnimationUtils.loadAnimation(getApplicationContext(),
                android.R.anim.slide_in_left));
        // 设置切出动画
        is.setOutAnimation(AnimationUtils.loadAnimation(
                getApplicationContext(), android.R.anim.slide_out_right));

    }
}

 

 

main.xml

 

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >

    <ImageSwitcher
        android:id="@+id/imageSwitcher1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >
    </ImageSwitcher>

</LinearLayout>
