android字体闪烁动画,使用线程和Timer实现
代码语言:javascript复制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)
}
}
