Android字体闪烁动画（线程）

Android字体闪烁动画，使用线程和Timer实现

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）    
    }   
}
