取消暂停/等待后延迟的处理程序/可运行，仍可以激活暂停的代码
|
设置：我有一个4阶段的活动，我使用一个后延迟处理程序来暂停两个嵌套的后延迟。
时间线：
stage1 | CODE FIRES | stage2 |代码火灾| stage3 |代码火灾|阶段4
阶段1：已停用，仅显示自定义警报对话框
阶段2：停用（主要是）为用户提供视觉效果，包括倒数计时器
阶段3：使用第二个倒数计时器停用
阶段4：用户互动，无倒计时或其他暂停
我希望用户能够通过按一下按钮跳到stage2的末尾，这将同时取消倒计时计时器和后延迟（而不会取消等待启动的代码）
我曾尝试分别取消两者，但都没有成功，这是我使用过的命令。
countdowntimer.cancel(); // this didn\'t work from the button or a void call
handler.removeCallbacks(runnable); // want to skip to end of stage2
public class Main extends Activity {
public Boolean onOffCDT = true;
public Handler handler2Mem;
public Runnable mem2Runnable = null;
public CountDownTimer aCounter;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
aCounter = null;
final Handler handlerMem = new Handler();
final Runnable memRunnable = new Runnable() {
public void run() {
//code
final CountDownTimer aCounter = new CountDownTimer(memTime, 100) {
public void onTick(long millisUntilFinished) {
//update time
if(onOffCDT.equals(false)) {
onOffCDT = true;
// aCounter.cancel();
}
}
public void onFinish() {
title.setText(tempTitle);
}
};
aCounter.start();
Handler handler2Mem = new Handler();
Runnable mem2Runnable = new Runnable() {
public void run() {
//code
CountDownTimer bCounter = new CountDownTimer(8000, 100) {
public void onTick(long millisUntilFinished) {
//update time
}
public void onFinish() {
title.setText(tempTitle);
}
};
bCounter.start();
stage3(8000); //another delay
};
}; handler2Mem.postDelayed(mem2Runnable, memTime);
}
}; handlerMem.postDelayed(memRunnable, 2500);
submit.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// this button checks stage#, if stage4 info - else...
}else{
aCounter.cancel();
onOffCDT = false;
cancelCountDown(mem2Runnable, handler2Mem);
}
}
});
}
private void stage3 (Integer tTime) {
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
//Do Stuff
}
}, tTime);
}
public void cancelCountDown(Runnable run2, Handler hand2) {
hand2.removeCallbacks(run2);
}

并在要取消时将其设置为true
