Question

How to add a custom button to allitems view of a custom list ?

Its just a list, and with only 1 view, i want to add a custom button on the view, which will navigate user to another page.

Answer 1

View pages are just web part pages.

You can edit the page add a button using a Content Editor Web Part above the list web part.

Edit:

This may be the way to go. Looks like you can add javascript to the page. With javascript you can render anything.

Edit2:

You can declare a view within a List Definition with the following markup

<View BaseViewID="2" 
      Name="8d2719f3-c3c3-415b-989d-33840d8e2ddb" 
      DisplayName="Overridable" 
      Type="HTML" 
      WebPartZoneID="Main" 
      SetupPath="pages\viewpage.aspx" 
      Url="Overridable.aspx"
      DefaultView="TRUE">
  <ViewFields>
    <FieldRef Name="Title" />
  </ViewFields>
  <Query />
  <Toolbar Type="Standard" />
  <XslLink>main.xsl</XslLink>
  <JSLink Default="TRUE">~site/Scripts/ButtonRender.js</JSLink>
</View>

Notice the JSLink attribute at the bottom.

Create the corresponding javascript file.

In the JS, the header template can be customized, which is one option for adding a button.

(function () {
    // Initialize the variable that stores the objects.
    var overrideCtx = {};
    overrideCtx.Templates = {};

    overrideCtx.Templates.Header = "<div><button>Test Button</button><br /><#=ctx.ListTitle#>";

    // Set the template to the:
    //  Custom list definition ID
    //  Base view ID
    overrideCtx.BaseViewID = 2;
    overrideCtx.ListTemplateType = 10057;

    // Register the template overrides.
    SPClientTemplates.TemplateManager.RegisterTemplateOverrides(overrideCtx);
})();

EDIT3:

The default header can be maintained by using this changing the header definition line to (Source):

overrideCtx.Templates.Header = "<div><button>Test Button</button><br /><#=ctx.ListTitle#>" + RenderTableHeader(overrideCtx) + "</table>";

As noted in the linked post, the RenderTableHeader method prints the default table, but doesn't print the table close(Maybe?).

I have not tested this as I don't have a 2013 env in front of me, but this should get you close.
