Click Splash Enter MainActivity

参考鸿神原文

1. 默认 AActivity 为闪屏页，BActivity 为主页面

2. Intent.FLAG_ACTIVITY_SINGLE_TOP说明

   • 当用户点击 HOME 键后，时刻一到并不会自动开启 BActivity，而是后端自动跳转完成

   • 当用户进入本 APP 其他页面时，时刻一到自动跳转至 BActivity

     public class AActivity extends Activity {
     
         private Handler handler = new Handler() {
             @Override
             public void handleMessage(Message msg) {
                 Intent it = new Intent(getApplicationContext(), BActivity.class);
                 
                 // 当用户进入该APP其他页面时,时刻一到自动跳转至B页面
                 it.setFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP);
                 startActivity(it);
                 finish();
     
                 handler.removeMessages(-1);
             }
         };
     
         @Override
         protected void onCreate(Bundle savedInstanceState) {
             super.onCreate(savedInstanceState);
             setContentView(R.layout.activity_a);
     
             handler.sendMessageDelayed(handler.obtainMessage(-1), 3000);
         }
     
         @Override
         public boolean onTouchEvent(MotionEvent event) {
             if (event.getAction() == MotionEvent.ACTION_UP) {
                 handler.sendMessage(handler.obtainMessage(-1));
                 finish();
             }
             return super.onTouchEvent(event);
         }
     }
