我是一个总的新手,我想学习Android开发很抱歉,如果这个问题已经问Android的标签显示在列表视图中的新片段点击
我只是做了显示2个选项卡的新的应用程序,列表视图,和一个选项页,两者都工作正常,但我想显示一个新的片段(项目的详细信息),当用户从列表视图中选择一个项目
我知道我必须在onClickListener中添加代码,但我不知道我需要添加...或者任何人都知道一个教程我可以阅读做到这一点?
感谢您的帮助
这是我的第一个片段(hotelsFragment.java)
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.AdapterView;
import android.widget.ListAdapter;
import android.widget.ListView;
public class hotelsFragment extends Fragment {
String[] hotels = {"Hotel 1", "Hotel 2", "Hotel 3", "Hotel 4", "Hotel 5", "Hotel 6"};
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.hoteles_fragment, container, false);
ListView hotelsListView = (ListView) view.findViewById(R.id.hotelslist);
ListAdapter hotelsListAdapter = new hotelsAdapter(getContext(), hotels);
hotelsListView.setAdapter(hotelsListAdapter);
hotelsListView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
@Override
public void onItemClick(AdapterView<?> adapterView, View view, int position, long id) {
// I want to show a new fragment in here
}
});
return view;
}
}
其XML:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.miempresaenlanube.hoteles360.MainActivity$PlaceholderFragment">
<ListView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:id="@+id/hotelslist"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true" />
</RelativeLayout>
这是类片段的我想说明:
import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
public class hotelMainFragment extends Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.hotel_main, container, false);
return view;
}
}
和XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:srcCompat="@drawable/hotel"
android:id="@+id/imageView2"
android:layout_alignParentTop="true"
android:layout_alignParentStart="true"
android:scaleType="centerCrop" />
</RelativeLayout>
主要活动XML:
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.CoordinatorLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/main_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:fitsSystemWindows="true"
tools:context="com.miempresaenlanube.hoteles360.MainActivity">
<android.support.design.widget.AppBarLayout
android:id="@+id/appbar"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:paddingTop="@dimen/appbar_padding_top"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="?attr/colorPrimary"
app:layout_scrollFlags="scroll|enterAlways"
app:popupTheme="@style/AppTheme.PopupOverlay">
</android.support.v7.widget.Toolbar>
<android.support.design.widget.TabLayout
android:id="@+id/tabs"
android:layout_width="match_parent"
android:layout_height="wrap_content" />
</android.support.design.widget.AppBarLayout>
<android.support.v4.view.ViewPager
android:id="@+id/container"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_marginBottom="?attr/actionBarSize"
app:layout_behavior="@string/appbar_scrolling_view_behavior" />
</android.support.design.widget.CoordinatorLayout>
即时得到这个错误你的活动框架布局:java.lang中。抛出:IllegalArgumentException:未发现ID 0x7f0c0073(com.miempresaenlanube.hoteles360:ID /容器)视图中的片段hotelMainFragment {131022a#0的id = 0x7f0c0073},其奇怪,因为我的容器确实命名容器 – Chico3001
我不能看到容器内Framlayout'hotelsFragment'请更新您的代码或使用该'fragmentTransaction.add(新hotelMainFragment(),标签).commit();' –
它显示了错误......无法解析法“添加(com.miempresaenlanube.hoteles360.hotelMainFragment,INT)” – Chico3001
