作为一个android的菜鸟,前些天在做项目的时候用到了fragment,需求是从一个Fragment跳转到另一个Fragment,并且还要传递数据,就像Activity的跳转一样。在网上找了好久都没找到很好的列子,最后通过看别人的博客和查文档终于做好了,现在整理一下,希望能帮助有需要的童鞋。
1、首先在第一个Fragment 里面拿到FragmentManger 和FragmentTransaction 代码如下。
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
fm = getFragmentManager();
}
2 准备要传递的数据跳转。
deptListView.setOnItemClickListener(new OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> arg0, View arg1, int postion,
long arg3) {
ft = fm.beginTransaction();//注意。一个transaction 只能commit一次,所以不要定义成全局变量
long id = adapter.getDepartments().get(postion).getId();
String name = adapter.getDepartments().get(postion).getName();
DeptDocFragment df = new DeptDocFragment();
Bundle bundle = new Bundle();
bundle.putLong("id", id);
bundle.putString("name", name);
df.setArguments(bundle);
ft.replace(R.id.guide_content, df);
ft.addToBackStack(null);
ft.commit();
}
});
上面的DeptDocFragment就是我要跳转的Fragment,而传递数据跟Activity一样,用Bundle,最后通过df.setArguments(bundle);携带数据。通过replace方法切换Fragment实现跳转,最后别忘了commit
提交。
3 接下来就是在另一个Fragment 中获取第一个Fragment 传递过来的数据。
@Override
public void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
Bundle bundle = getArguments();
deptId = bundle.getLong("id");
deptName = bundle.getString("name");
}
在Fragment的onCreate()
方法中获取数据。然后在这个Fragment中完成你需要的逻辑。好了,整个Fragment的跳转就算是完成了。希望对需要的童鞋有帮助。。。
