Android Studio：IDE致命错误。不自动建议+编译应用程序有点错误

我不是处理这些东西的专家（修复IDE＆＃39; s）但我得到了116个例外：

  

等于对象必须具有相同的哈希码。在重拍期间，Trove   发现以下两个对象声称是平等的（如   java.lang.Object.equals（）或TObjectHashingStrategy.equals（））但是   他们的hashCodes（或由你的TObjectHashingStrategy计算的）   是不平等的。这违反了一般合同   java.lang.Object.hashCode（）。请参阅该方法中的第二点   文档。 object＃1 = PsiArrayAccessExpression：args [0]（类   com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）   的hashCode = 1492582784; object＃2 = PsiArrayAccessExpression：args [0]   （类   com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）   hashCode = 1492582784：等于对象必须具有相等的哈希码。中   重复，Trove发现以下两个对象声称是   等于（如java.lang.Object.equals（）或   TObjectHashingStrategy.equals（））但是他们的hashCodes（或那些   由你的TObjectHashingStrategy计算得并不相等。这违反了   java.lang.Object.hashCode（）的常规协定。见子弹点   两个在该方法的文档中。对象＃1   = PsiArrayAccessExpression：args [0]（类com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl），   的hashCode = 1492582784; object＃2 = PsiArrayAccessExpression：args [0]   （类   com.intellij.psi.impl.source.tree.java.PsiArrayAccessExpressionImpl）   的hashCode = 1492582784

即使在重新启动IDE后，它仍然会给我带来麻烦。 它不会自动建议或填充变量/函数等。我必须让我的应用程序字面上只是记住事情，我该如何解决这个问题？这很烦人。

我注意到每次按Ctrl + Space时都会抛出它（对于自动建议）。

帮助？

答案 0 :(得分：0)

对于那些看过这几年但仍然无法找到解决方案的人，我遇到了同样的问题并最终解决了问题。如果你遇到类似的情况，请参见下文。

我的问题是使用JSONObject和JSONArray对象。基本上，我会读取一个JSONObject，并尝试在第一个JSONObject中获取另一个JSONObject

假设您正在阅读此消息：

{
    "sub1": ["array element 1", "array element 2", "array element 3"],
    "sub2": {
                "name": "name for sub-object sub2",
                "value": "value for sub-object sub2 or whatever"
            }
}

让我们说整个对象是args[0]给我的，然后我正在做的就是这样：

JSONObject globalObject = (JSONObject) args[0];
JSONArray sub1= (JSONArray) globalObject.get("sub1");//<-- the problem
JSONObject sub2 = (JSONObject) globalObject.get("sub2");//<-- also the problem

String arrayElement1 = sub1.get(0);
String nameSub2 = sub2.getString("name");

<强>解决方案 问题来自于将内容从JSONObject / JSONArray的get()方法转换为JSONObject / JSONArray。没有必要这样做，因为您可以getJSONObject(/*value*/)或getJSONObject(/*value*/)，并获得已经类型为JSONObject或JSONArray

的结果

所以我上面的代码应该是这样的：

JSONObject globalObject = (JSONObject) args[0];//<--only this needs to be casted
JSONArray sub1= globalObject.getJSONArray("sub1");//<-- got rid of the castnig
JSONObject sub2 = globalObject.getJSONObject("sub2");//<-- no more casting

String arrayElement1 = sub1.get(0);
String nameSub2 = sub2.getString("name");

希望这有助于某人。
