Android之TextSwitcher

一. 简单示例

src

public class AndroidUIActivity extends Activity {

	// 索引
	private int index;
	// 文本数组
	private String[] poemArray = { "we", "are", "good", "friends" };

	/** Called when the activity is first created. */
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);

		//定义文字切换器
		final TextSwitcher ts = (TextSwitcher) findViewById(R.id.textSwitcher1);

		//定义视图显示工厂，并设置
		ts.setFactory(new ViewFactory() {

			public View makeView() {
				TextView tv =new TextView(AndroidUIActivity.this);
				tv.setTextSize(32);
				tv.setTextColor(Color.GREEN);
				return tv;
			}
		});

		// 设置图片来源
		ts.setText(poemArray[index]);

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

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

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

	}
}
