android-welcome page

The main idea of ​​implementing the welcome page is to create an activity, lay out the welcome interface in XML, set a handler message mechanism in the main java file, define a time, automatically jump to the main page and close the current page (PS: the page should be set to start page)

//        用handler定时，完成启动页面
        new Handler().postDelayed(new Runnable() {
    
    
            @Override
            public void run() {
    
    
                startActivity(new Intent(ActionActivity.this,MainActivity.class));
                finish();
            }
        }, 2000);
