我有兩個片段是活動的,並在平板電腦上並排顯示。當用戶從fragmentA中的列表視圖中選擇一個項目時,我需要將fragmentA中的一些數據傳遞給fragmentB。嘗試從活動獲取數據到fragmentB時發生問題。我收到錯誤:IlligalStateException:碎片已經激活。將數據傳遞到添加的片段 - IlligalStateException:片段已經激活
我通過將數據從活動是這樣的:
@Override
public void onTrackSelected(String trackId) {
topBarFragment topBarFragment = (topBarFragment)getSupportFragmentManager().findFragmentById(R.id.topBar_fragment);
Bundle bundle = new Bundle();
bundle.putString("trackId", trackId);
//set Fragmentclass Arguments
topBarFragment.setArguments(bundle);
topBarFragment.onTrackSelected();
}
然後在fragmentB收到這樣:
public void onTrackSelected() {
String trackId = getArguments().getString("trackId");
Toast.makeText(getActivity().getApplicationContext(), trackId,Toast.LENGTH_SHORT).show();
}
}
的logcat:
