android 如何从activity跳转到另一个activity下指定的fragment

时间:2021-12-12 08:55:35

思路:

跳转到目标fragment所在的activity,并传递一个flag,来确定要到哪个fragment,根据该flag判断后,跳转到指定的fragment即可。

代码:

当前界面:

intent.putExtra("fragment_flag", 3);

目标界面:

fragmentFlag = intent.getIntExtra("fragment_flag", 1);
fManager = getSupportFragmentManager();
FragmentTransaction transaction = fManager.beginTransaction();
switch (fragmentFlag){
    case 1:
        transaction.replace(R.id.fl_radio_show, mFragments[0]);
        navigationBar.check(R.id.tab_monitor_home);
        break;
    case 2:
        transaction.replace(R.id.fl_radio_show, mFragments[1]);
        navigationBar.check(R.id.tab_monitor_publish);
        break;
    case 3:
        transaction.replace(R.id.fl_radio_show, mFragments[2]);
        navigationBar.check(R.id.tab_monitor_me);
        break;
}
transaction.commit();
