android - 一一检查ArrayList of Strings是否包含50个不同的String

Question

如何检查字符串的ArrayList是否包含字符串数组中的50个不同字符串中的每一个，并对ArrayList中的每个相同字符串做某事？

Answer 1

您可以使用此函数来检查数组中的所有字符串是否也在 ArrayList 中。如果您想添加额外的逻辑，例如每次找到匹配项时执行 doSomething()，您应该能够轻松调整代码。

ArrayList myList; // let's assume its initialized and filled with Strings
String[] strArray; // let's assume its initialized and filled with Strings

//this function returns true if all Strings in the array are also in your arraylist

public boolean containsAll(myList, strArray){
  //iterate your String array
  for(int i = 0; i < strArray.length; i++){
    if(!myList.contains(strArray[i])){
      //String is not in arraylist, no need to check the rest of the Strings
      return false;
    }
  }
 return true; 
}
