//从启动界面跳转到主界面
        new Handler().postDelayed(new Runnable() {

            @Override
            public void run() {
                Intent intent03 = new Intent();
                intent03.setClass(Firstone.this, MainActivity.class);
                startActivityForResult(intent03, RESULT_OK);
                overridePendingTransition(R.anim.fade,R.anim.hold);
                Firstone.this.finish();
            }
        },3000);
