Smobiler is a development platform that uses the. Net language to develop apps in the VS environment. It may be more convenient than Xamarin.

 

1. Target Style

The following operations are required to achieve the effect:

1. Drag a Timer control, a TextBox Control, a Button control, a label control, and an Image control from the "scycler Components" on the toolbar to the form interface.

2. Tick event of the Timer control

VB：    Private Sub timer1_Tick(sender As Object, e As EventArgs) Handles timer1.Tick       Me.TextBox1.Text = (Convert.ToInt32(Me.textBox1.Text.ToString()) - 1).ToString()   End Sub

C#:   private void timer1_Tick(object sender, EventArgs e)   {       this.textBox1.Text =(Convert.ToInt32(this.textBox1.Text.ToString()) -1).ToString();          }

Note: Call the Timer control

3. TextChanged event of TextBox

VB：   Private Sub textBox1_TextChanged(sender As Object, e As EventArgs) Handles textBox1.TextChanged        If Me.textBox1.Text = "0" Then           timer1.Stop()       Else           timer1.Start()       End If   End Sub

C#:   private void textBox1_TextChanged(object sender, EventArgs e)   {        if(this.textBox1.Text =="0")       {           timer1.Stop();       }       else       {           timer1.Start();       }   }

Note: Determine whether to start or stop the timer based on the conditions.

4. Click events of the Button control

VB：   Private Sub button1_Click(sender As Object, e As EventArgs) Handles button1.Click        Me.textBox1.Text = "60"   End Sub

C#:   private void button1_Click(object sender, EventArgs e)   {        this.textBox1.Text ="60";         }

5. Modify the attribute a. Interval of the Timer control.

Interval for triggering a Tick event, in seconds. The default value is 1, indicating that the interval is 1 second;

Ii. Mobile phone effect display
