我有一个导航活动，其中包含10个由WebView组成的片段。
现在，当我从“ A”片段输入/传输到“ B”，然后再onBackPress输入/传输时，它会转换回“ A”，但会重新加载。
我想回到留有“ A”的位置。

如果您想正确执行操作，请使用{
"IndustryCode": [{
"attrCodeValue": 25838,
"attrTypeText": "DBH Industry Code",
"IndustryCode": {
"txt": "1063"
},
"IndustryCodeDescription": [{
"attrLanguageCode": 39,
"attrIndustryCodeDescriptionLengthCode": 9120,
"txt": "Legal Services"
}],
"DisplaySequence": 1
},
{
"attrCodeValue": 700,

，这里是guide。
如果这太复杂了，您可以通过在片段ViewModel期间将数据保存在活动中的某个位置来模仿ViewModel。例如：
onPause()并添加到您的boolean alreadyLoaded = true;
boolean btn1Shown = true;
String editText1Text = editText1.getText().toString;
onCreateView()这可能需要一些接口或公共活动方法，这就是为什么存在ViewModel的原因，因此您不必执行这些操作。
