java - 如何解决 java.lang.ArrayStoreException

Question

在 Android Studio 中出现以下错误:

获取:

java.lang.ArrayStoreException: source[0] of type com.example.glide.ImageList cannot be stored in destination array of type java.lang.String[] in this line

代码:

ArrayList<ImageList> list = new ArrayList<>();
Object[] objNames = list.toArray();
String[] strNames = Arrays.copyOf(objNames, objNames.length, String[].class);
for(int j=0; j < strNames.length; j++){
    strNames[j] = String.valueOf(list.get(j));
    Log.d("String : {} ", strNames[i]);
}

你的程序有很多逻辑错误。

但试试这个

public static void main(String[] args) {
    ArrayList<ImageList> list = new ArrayList<>();
    list.add(new ImageList()); //adding some dummy objects, you add yours
    list.add(new ImageList());
    String[] strNames = new String[list.size()];
    for(int j=0; j < strNames.length; j++){
         strNames[j] = String.valueOf(list.get(j));
         Log.d("String : {} ", strNames[i]);
    }
 }
