在Android中,可以通過以下方式實現ArrayMap的迭代器:
ArrayMap<String, String> arrayMap = new ArrayMap<>();
arrayMap.put("key1", "value1");
arrayMap.put("key2", "value2");
for (int i = 0; i < arrayMap.size(); i++) {
String key = arrayMap.keyAt(i);
String value = arrayMap.valueAt(i);
// Do something with key and value
}
ArrayMap<String, String> arrayMap = new ArrayMap<>();
arrayMap.put("key1", "value1");
arrayMap.put("key2", "value2");
Set<Map.Entry<String, String>> entrySet = arrayMap.entrySet();
Iterator<Map.Entry<String, String>> iterator = entrySet.iterator();
while (iterator.hasNext()) {
Map.Entry<String, String> entry = iterator.next();
String key = entry.getKey();
String value = entry.getValue();
// Do something with key and value
}
以上兩種方法都可以實現ArrayMap的迭代器,可以根據具體需求選擇合適的方式來遍歷ArrayMap中的元素。
