Question

我应用了幻灯片转换，通过活动A转到活动B. 活动A - ＆gt;活动B
当我回到活动A（通过按下后退按钮）时活动B - ＆gt;活动A
然后再次参加活动B
活动A - ＆gt;活动B

The O'Fallon, Missouri Police Department reported on Facebook today that armed robbers have used the app to lure victims in and rob them at gunpoint.\nThe police received reports about the robberies and were able to apprehend four suspects in the area. Apparently, the thieves used the app to set up a beacon at a Pokéstop within the game. Using this method, Sergeant Bill Stringer of the OPD told Motherboard that the culprits were able to rob 11 players, all between the ages of 16 and 18, in the St. Louis and St. Charles counties of Missouri.");
    Slide slide =   new Slide(Gravity.BOTTOM);
    slide.addTarget(tv2);
    getWindow().setEnterTransition(slide);
}

}

Answer 1

在onClick（）方法内的Activity Anima 中移动捆绑初始化。尝试

iv.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        bundle = ActivityOptions.makeSceneTransitionAnimation(Anima.this).toBundle();
        Intent intent = new Intent(Anima.this,Second.class);
        startActivity(intent,bundle);
    }
});

应用程序因转换而无响应
