如何将片段的变量传递给活动?
例如片段:
int diffDays = 0;
int diffHours = 0;
int diffMinutes = 0
的活动:
private void testMethod(){
System.out.print(diffDays);
}
答案 0 :(得分:0)
你的片段:
friendList.setModel(new javax.swing.AbstractListModel() {
URL url = getClass().getResource("friends");
File folder = new File(url.getPath());
File[] listOfFiles = folder.listFiles();
String[] elements = new String[listOfFiles.length];
for(int i=0; i<listOfFiles.length;i++) {
elements[i] = (listOfFiles[i].getName());
}
然后在你的活动中:
public class frag extends Fragment{
private int data;
public int getData(){
return data;
}
}
