Question

我需要创建一个像下面这样的片段。

点击Need Cash TextView将更改包含的布局，其中包含两个按钮Cancel＆amp; Meet并在这些观点之间切换。

但是当我点击需要现金通话时，toggleVisibility()功能会使Need Cash隐身，但不显示Cancel | Meet。

我在这个过程中犯了什么错误？

修改

public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        View thisView =  inflater.inflate(R.layout.fragment_map, container, false);
return thisView;
}

编辑2

点击之前的片段视图，显示保持现金TextView

点击后的片段视图未显示＆＃39;取消＆＃39;并且＆＃39;见面＆＃39; TextViews

**编辑3 ** 给予外部RelativeLayout的id并使其无效

public void toggleVisibility() {
        if(needCashTv.getVisibility() == View.VISIBLE) {
            //needCashTv.setEnabled(false);
            needCashTv.setVisibility(View.GONE);

            frameForNeedCashStuff.setVisibility(View.VISIBLE);
            //cancelNeedCashTv.setEnabled(true);
            cancelNeedCashTv.setVisibility(View.VISIBLE);
            //letsMeetneedCashTv.setEnabled(true);
            letsMeetneedCashTv.setVisibility(View.VISIBLE);
            frameForNeedCashStuff.bringToFront();

Answer 1

RelativeLayout TextView包裹tv_need_cash_cancel tv_need_cash_lets_meet和View.invalidate()已设置为“已消失”。

如果您只是切换子视图的可见性，它将永远不会显示。

您确定还需要regexp {.*%MKA-5-SESSION_START: +$(.*) +:.*$ +MKA Session started for.*([0-9A-Fa-f]{4}.[0-9A-Fa-f]{4}.[0-9A-Fa-f]{4}).*AuditSessionID +(.*), +AuthMgr-Handle +(.*)} $op - intf mac auditsessid authmgrhdl吗？如果您只是切换可见性，则没有必要。

当两个小部件一个在另一个之上时，设置小部件可见性
