android中的字体闪烁

package com.android.WordAnimation;import java.util.Timer;import java.util.TimerTask;import android.app.Activity;import android.graphics.Color;import android.os.Bundle;import android.widget.TextView;public class WordAnimationActivity extends Activity {    private int clo = 0;    /** Called when the activity is first created. */    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        spark();    }    public void spark() {        final TextView touchScreen = (TextView)findViewById(R.id.TextView01);        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);                        } else {                            if (clo == 1) {                                clo = 2;                                touchScreen.setTextColor(Color.YELLOW);                            } else if (clo == 2){                                clo = 3;                                touchScreen.setTextColor(Color.RED);                            } else {                                clo = 0;                                touchScreen.setTextColor(Color.BLUE);                            }                        }                    }                });            }        };        timer.schedule(taskcc, 1, 100);    }}

android的字体闪烁效果，

timer.schedule(taskcc, 1, 100);

其中的参数是：第二个参数分别是delay（多长时间后执行），第三个参数是：duration（执行间隔）单位为：ms
