Android:检测按键的轻量级解决方案

活动类字段:

private static final int KEY_TIMEOUT = 60000;
private long lastKeyEventTime;
private boolean checkKey;

在活动.onCreate() :

checkKey = true;

Thread t = new Thread(){
    while (checkKey){
        if (lastKeyEventTime!=0 && System.currentTimeMillis()-lastKeyEventTime>TIMEOUT){
            // TIMEOUT
        }

        try {
          Thread.sleep(500);
        } catch (InterruptedException e) {
          e.printStackTrace();
        }
    }
}
t.start();

在活动.onDestroy():

checkKey = false;

lastKeyEventTime = System.currentTimeMillis();
