android实现字体闪烁动画的方法

public class ActivityMain extends Activity { public void onCreate(Bundle savedInstanceState) {  super.onCreate(savedInstanceState);  setContentView(R.layout.main);  spark(); } private int clo = 0; public void spark() {  final TextView touchScreen = (TextView) findViewById(R.id.TextView01);// 获取页面textview对象  Timer timer = new Timer();  TimerTask taskcc = new TimerTask(){   public void run() {    runOnUiThread(new Runnable() {     public void run() {      if (clo == 0) {       clo = 1;       touchScreen.setTextColor(Color.TRANSPARENT); // 透明      } else {       if (clo == 1) {        clo = 2;        touchScreen.setTextColor(Color.RED);       } else {        clo = 0;        touchScreen.setTextColor(Color.GREEN);       }      }     }    });   }  };  timer.schedule(taskcc, 1, 300);  // 参数分别是delay（多长时间后执行），duration（执行间隔） }}
