Android字體閃爍動畫（線程）

Android字體閃爍動畫，使用線程和Timer實現

1. public class ActivityMain extends Activity {  
2.     public void onCreate(Bundle savedInstanceState) {  
3.         super.onCreate(savedInstanceState);  
4.         setContentView(R.layout.main);  
5.         spark();  
6.     }  
7.   
8.   
9.     private int clo = 0;  
10.     public void spark() {  
11.         final TextView touchScreen = (TextView) findViewById(R.id.TextView01);// 獲取頁面textview對象   
12.         Timer timer = new Timer();  
13.         TimerTask taskcc = new TimerTask(){  
14.   
15.             public void run() {  
16.                 runOnUiThread(new Runnable() {  
17.                     public void run() {  
18.                         if (clo == 0) {  
19.                             clo = 1;  
20.                             touchScreen.setTextColor(Color.TRANSPARENT); // 透明   
21.                         } else {  
22.                             if (clo == 1) {  
23.                                 clo = 2;  
24.                                 touchScreen.setTextColor(Color.RED);  
25.                             } else {  
26.                                 clo = 0;  
27.                                 touchScreen.setTextColor(Color.GREEN);  
28.                             }  
29.                         }  
30.                     }  
31.                 });  
32.             }  
33.         };  
34.         timer.schedule(taskcc, 1, 300); // 參數分別是delay（多長時間後執行），duration（執行間隔）   
35.     }  
36. }
