如何从静态方法中调用非静态方法？

我想从静态方法中调用非静态方法：

Class SMS
{
    public static void First_function()
    {
        SMS sms = new SMS();
        sms.Second_function();
    }

    public void Second_function()
    {
        Toast.makeText(getApplicationContext(),"Hello",1).show(); // This i anable to display and cause crash
        CallingCustomBaseAdapters();    //this was the adapter class and i anable to call this also
    }

我可以调用 Second_function 但是不能获得 Toast 和 CallCustomBaseAdapter() 方法，然后就出现崩溃。
如何处理这个问题呢？

CallingCustomBaseAdapters()是类外函数吗,注意作用域,错误提示应该说的清楚
getApplicationContext()前面默认有activity的this,你这样this变味了
你可改为这个，Toast就出来了

public void Second_function(Context ct)
    {
        Toast.makeText(ct,"Hello",1).show();
    }


//.......
SMS sms = new SMS();
Context ct = getApplicationContext();
sms.Second_function(ct);
