android - 如何展开和折叠以 EditText 作为其子项的 textView

Question

我是 android 新手..在我的 xml 文件中，我使用了三个 TextView ，在里面我为每个 TextView 使用了三个 edittext ..我想要的是当我按下一个特定的 TextView 时，它必须展开才能得到它们child(edittexts)..当我再次按下时，textview 应该会折叠起来。

现在在我的代码中，当我按下 textview 时它会展开，但是当我再次按下时它不会折叠。

下面是我的代码..任何帮助将不胜感激...提前致谢..

Answer 1

检查 View 是否可见 onClick 的 TextView:

if(panelProfile.getVisibility() == View.VISIBLE) {
    panelProfile.setVisiblity(View.GONE);
} else {
   panelProfile.setVisiblity(View.VISIBLE);
}

注意:您要多次声明下面的代码，而不是只声明一次。

View panelProfile = findViewById(R.id.panelProfile);

同上，

View panelSettings = findViewById(R.id.panelSettings);
View panelPrivacy = findViewById(R.id.panelPrivacy);
