1.startActivity(intent)
2.startActivityForResult:a.启动BActivity 请求码为0:startActivityForResult(intent,0);
b.重写onActivityResult(int requestCode,int resultCode,Intent data),回调的方式来获取指定Activity返回的结果;
c.在跳转后的页面回转:
//将数据放入Bundle对象中
Bundle bundle=new Bundle(); bundle.putString("name", city[1]); bundle.putString("names", citys[1]); // 获取启动该Activity之前的Activity对应的Intent Intent intent=getIntent(); intent.putExtra("name", bundle); //设置当前Activity的结果码 setResult(0, intent); //关闭当前的Activity finish();
