我正在使用启动页面“使用Google登录”。当用户拥有多个帐户时......在他们选择要登录的帐户后,我正在尝试启动应用程序主要活动,但出于某种原因,我的片段中永远不会调用onActivityResult
。 / p>
在活动中,我调用onActivityResult
并让它调用super以便片段可以处理它,但它永远不会触发。
有什么建议吗?
以下是有问题的片段:

关键是在第一个活动中调用以下方法。
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
答案 1 :(得分:1)
在外部活动中添加:
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
Fragment fragment = getSupportFragmentManager().findFragmentById(R.id.change_to_your_id);
fragment.onActivityResult(requestCode, resultCode, data);
}

正确解决此问题您可以使用已准备好的解决方案accountPicker 但是 - 如果你想设计自己的解决方案 - 一个想法是开始你的第二个活动(显然从第一个活动开始):
Intent intent = this.getIntent();
intent.putExtra(... /* some code that will control second activity */
startActivityForResult(intent, request_code);
然后当活动做了所有必须做的事情你允许它返回:
Intent intent = this.getIntent();
intent.putExtra(... /* all needed results to return */ );
this.setResult(RESULT_OK, intent);
finish();
最后,这是你的第一个活动,然后在其onActivityResult中获得结果。
