Java - 等待Runnable完成

您也可以像这样使用JDK的标准RunnableFuture：

RunnableFuture task = new FutureTask<>(runnable, null);
runOnUiThread(task);
try {
    task.get(); // this will block until Runnable completes
} catch (InterruptedException | ExecutionException e) {
    // handle exception
}

myRunnable.wait()将释放锁定myRunnable并等待通知

我们总是在等待前添加支票.

//synchronized wait block
while(myRunnable.needWait){
    myRunnable.wait();
}

//synchronized notify block
this.needWait = false;
myRunnable.notify();
