Fragment already added异常解决方案

Fragment showFg;

boolean isFirstCreated = false;

if (!fragment.isAdded() &&null == getSupportFragmentManager().findFragmentByTag("TAG" +tagPage)

&&isFristCreated) {

if (showFg !=null) {

ft.hide(showFg).add(fragment, "TAG" +tagPage);

    }else {

ft.add(fragment, "TAG" +tagPage);

    }

}else {//已經載入進容器裡去了....

    if (showFg !=null) {

ft.hide(showFg).show(unlockConfirmDialog);

    }else {

ft.show(unlockConfirmDialog);

    }

}

showFg =fragment;

if (!isFinishing()) {

ft.commitAllowingStateLoss();

    getSupportFragmentManager().executePendingTransactions();

}

新建Fragment的时候将isFristCreated置为true。

Fragment fragment =new Fragment();

isFristCreated =true;

亲测有效。。
