Design your own prompt Dialog for Android Custom Controls

When you need to design your own dialog box dialog and customize it according to your own requirements, such as the most common operation prompt, the operation is successful, and the corresponding prompt is displayed when the operation fails.

First look at the effect:

Steps:

1. inherit from the dialog class and define SEVERAL VARIABLES

Private Boolean Flag; // What images are displayed?
Private String MSG, title; // Title and content
Private Textview tvmsg; // Display message box in layout File
Private Imageview icon; // Show image button in layout File
Private Button close; // Close button in layout File

2. Implement the parent class Constructor

Public Mydialog (context, Boolean Flag, String title, string MSG)
{
Super (Context );
This . Flag = flag;
This . MSG = MSG;
This . Title = title;
}

3. Override the oncreate method of the parent class

View code

Protected Void Oncreate (bundle savedinstancestate)
{
Super . Oncreate (savedinstancestate );
Setcontentview (R. layout. Dialog );
Tvmsg = (textview) findviewbyid (R. Id. msg );
Icon = (imageview) findviewbyid (R. Id. Icon );
Close = (button) findviewbyid (R. Id. OK );
If (FLAG)
Icon. setimageresource (R. drawable. OK );
Else Icon. setimageresource (R. drawable. Error );
Settitle (title );
Tvmsg. settext (MSG );
Setonclicklistener ();
}

4. Add a listener to the button

Private Void Setonclicklistener (){
Close. setonclicklistener ( New View. onclicklistener ()
{
@ Override
Public Void Onclick (view V)
{
Dismiss ();
}
});
}

Call method:

 Mydialog dialog = new mydialog (this, false, "Information prompt", "Your operation is incorrect ");
Dialog. Show ();
