我想顯示一個計數器,但它不是在這裏工作的計數器是我的代碼:顯示在xamarin
protected void t_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
EditText v2 = (EditText)FindViewById(Resource.Id.editText5);
counter1--;
if (counter1 <= 0) {
counter1 = 59;
timer1--;
}
if (timer1 <= 0) {
t.Stop();
}
try{
v2.Text = timer1+ ":"+ counter1;
}
catch(Exception e8)
{
AlertDialog.Builder builder = new AlertDialog.Builder (this);
builder.SetMessage (e8.Message);
builder.Create().Show();
}
}
`我得到這個錯誤:e8.Message「只有創建視圖原來的線程層級可以觸及其觀點。「字符串
我該如何解決這個問題?
