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>
