onItemClickListener之间的两个片段 [英] onItemClickListener between two fragments
本文介绍了onItemClickListener之间的两个片段的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我很新与android.I都试过，但没能发现我错过了什么。我使用的两个片段两个显示列表。现在我想改变列表数据的第二个片段，当用户在第一个列表项的点击。默认情况下零位索引将被选中，显示在第二个列表中的数据。我使用自定义的数组适配器，显示的列表中两个fragments.Please帮我出guys.Thanks审议。 在这里，我贴我的code：

解决方案
您可以创建界面，将监听器，并从第一个分片行动，并通过行动，你的活动。
而在你的活动，你可以在第二个片段更新数据。
公共接口的IFoo
{
公共无效美孚（）;
}
在第一个片段
IFoo的响应; //全局变量
私人ProductCategoryFragment（IFoo的RESP）
{
this.responder = RESP;
}
静态ProductCategoryFragment的newInstance（捆绑包，IFoo的RESP）{
ProductCategoryFragment productCategoryFragment =新ProductCategoryFragment（RESP）;
productCategoryFragment.setArguments（包）;
饼干= bundle.getString（BsharpConstant.WEB_SERVICES_COOKIES）;
TIDS = bundle.getStringArray（BsharpConstant.TAXONOMY_TID）;
publicPath = bundle.getString（BsharpConstant.PUBLIC_PATH）;
listProCategory = bundle.getStringArray（BsharpConstant.PRODUCT_CATEGORY_NAMES）;
返回productCategoryFragment;
}
和somewere的片段
responder.foo（）;
在你的活动
公共类ProductListActivity扩展活动实现的IFoo
{
...
公共无效美孚（）
{
//将数据传递到第二个片段
}
的onCreate
{
...
ProductCategoryFragment.newInstance（捆绑，这一点）;
}
}
请您片段全局变量来让他们获得在每一个瞬间
我希望这是明确的，会有所帮助。如果还不清楚，请随时提出更多的问题：）
I am very new with android.I have tried but not able to find out what i am missing. I am using two fragments two display the list. Now i want to change the list data in second fragment when user click on the first list item. By default zero position index will be selected to display the data in second list.

解决方案
You can create interface that will be listener for and action from first fragment and passing action to your activity.
And in your Activity you can update data in second Fragment.
public interface IFoo
{
public void foo();
}
in first Fragment
IFoo responder; //global variable
private ProductCategoryFragment(IFoo resp)
{
this.responder=resp;
}
static ProductCategoryFragment newInstance(Bundle bundle, IFoo resp) {
ProductCategoryFragment productCategoryFragment = new ProductCategoryFragment(resp);
productCategoryFragment.setArguments(bundle);
cookie = bundle.getString(BsharpConstant.WEB_SERVICES_COOKIES);
tids = bundle.getStringArray(BsharpConstant.TAXONOMY_TID);
publicPath = bundle.getString(BsharpConstant.PUBLIC_PATH);
listProCategory = bundle.getStringArray(BsharpConstant.PRODUCT_CATEGORY_NAMES);
return productCategoryFragment;
}
and somewere in fragment
responder.foo();
in your Activity
public class ProductListActivity extends Activity implements IFoo
{
...
public void foo()
{
//pass data to second fragment
}
onCreate
{
...
ProductCategoryFragment.newInstance(bundle, this);
}
}
Make your fragments global variable to have access them in every moment
I hope it is clear and would help. If is not clear, feel free to ask additional questions :)
