Xamarin android传递和重置活动之间的时间 [英] Xamarin android passing and reset time between activities

问题描述

活动和重置之间的时间从其他活动中消失

需要帮助请快速回复

嗨！我对xamarin不熟悉的每个人都很有帮助。

我想把时间花在SeeTime活动上，并将时间重置为60，这也将重置MainActivity中的时间。



我尝试过：

Pass time between activity and reset from other activity
Need Help Kindly reply fast
Hi! Everyone I'm new to xamarin kindly helps me.
I want to pass time to SeeTime activity and reset time to 60 from that activity which will also reset time in the MainActivity.

What I have tried:

Code of MainActivity:

public class MainActivity : AppCompatActivity
{
public EditText timer;
Button btn;
public int elapsedTime; // counting values integer
Handler myHandler; // used to delay runnable for a second which delay_RATE
int delay_RATE = 1000; //delay
Java.Lang.Runnable r;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.activity_main);
elapsedTime = 60; // default value
myHandler = new Handler(); //initializing handler
r = new Java.Lang.Runnable(Run);
timer = FindViewById(Resource.Id.timertxt);
btn = FindViewById(Resource.Id.btn1);
btn.Click += Btn_Click;
Counter();
}

private void Btn_Click(object sender, System.EventArgs e)
{
elapsedTime = 20;
StartActivity(typeof(SeeTime));
}

void Counter()
{
elapsedTime--; // increment
timer.Text = elapsedTime.ToString();
myHandler.PostDelayed(r, delay_RATE);
if (elapsedTime == 0)
{
elapsedTime = 20;
}
}
void Run()
{
Counter();
}
}

Code of SeeTimer Activity:

public class SeeTime : Activity
{
MainActivity mainActivity;
private EditText timer;
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.Time);
timer = FindViewById(Resource.Id.txtTime);
mainActivity = new MainActivity();
timer.Text = mainActivity.timer.Text;
// Create your application here
}
}
