Question

其中一个布局显示了视图的可见性切换。布局有两个按钮，例如b1和b2。两个按钮显示/展开各自的RelativeLayout。单击按钮时，RelativeLayout的可见性将切换。

在b1 click上展开的RelativeLayout具有edittext实现。 b2在其中扩展RelativeLayout并使用TableLayout。这就是我试图展示的内容：

问题是，有时TableLayout不可见。就像这样：

这是onClick实现：

public void onClick(View view) {
    switch (view.getId()) {
        case R.id.btnSearchByName:
            if (rlSearchByName.getVisibility() == View.VISIBLE) {
                rlSearchByName.setVisibility(View.GONE);
            } else {
                rlSearchByName.setVisibility(View.VISIBLE);
            }
            break;
        case R.id.btnSearchByPartNo:
            if (rlSearchByPartNo.getVisibility() == View.VISIBLE) {
                rlSearchByPartNo.setVisibility(View.GONE);
            } else {
                rlSearchByPartNo.setVisibility(View.VISIBLE);
            }
            break;
