android – 使用操作栏中的选项卡处理屏幕方向的片段

问题是以前保存的状态中的选项卡已经存在碎片.你必须停用它们.

这是TabListener的构造函数的代码片段：

public TabListener(Activity activity,String tag,Class<T> clz,Bundle args) {
        mActivity = activity;
        mTag = tag;
        mClass = clz;
        mArgs = args;

        // check to see if we already have a fragment for this tab,probably
        // from a prevIoUsly saved state.  If so,deactivate it,because our
        // initial state is that a tab isn't shown.
        mFragment = mActivity.getFragmentManager().findFragmentByTag(mTag);
        if (mFragment != null && !mFragment.isDetached()) {
            Fragmenttransaction ft = mActivity.getFragmentManager().begintransaction();
            ft.detach(mFragment);
            ft.commit();
        }
    }

希望我能帮助你.
