我在45分钟内有一个CountDownTimer
扩展课程。
我希望在Activity
完成后(CountDownTimer
),在用户所在的任何地方(onFinish
或Activity
)拨打新的Fragment
。
我该怎么做?
这是我的Counter类:
public class Counter extends CountDownTimer {
private static long millis;
private static Counter instance;
private Counter(long millisInFuture, long countDownInterval){
super(millisInFuture,countDownInterval);
}
public static Counter initInstance(){
instance = new Counter(2700000, 1000);
return instance;
}
public static Counter getInstance() throws Exception{
if(instance==null){
throw new Exception("Parameters not initialized. Initiate with initInstance");
} else{
return instance;
}
}
public boolean isFinish(){
return millis <= 0;
}
@Override
public void onTick(long l) {
millis = l;
}
@Override
public void onFinish() {
// THIS IS WHERE I WANT TO CALL A NEW ACTIVITY !
}
}
我这样打电话给我的柜台:
Counter counterClass = Counter.initInstance();
counterClass.start();
答案 0 :(得分:1)
您只需要向计数器的构造函数发送一个Context,将其作为属性保存在您的计数器中,然后像这样调用您的计数器:
Counter counterClass = Counter.initInstance(getApplicationContext());
counterClass.start();
然后在你的结束时你可以正常开始一项活动:
context.startActivity()
