本文实例为大家分享了Android仿京东分类效果展示的具体代码，供大家参考，具体内容如下
1.写一个fragment
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.TextView;public class MyFragment extends Fragment { @Override public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) { // TODO Auto-generated method stub View view = inflater.inflate(R.layout.myfragment, null); TextView tv_title = (TextView) view.findViewById(R.id.tv_title); //得到数据 PersionInfo info = (PersionInfo) getArguments().getSerializable("info"); tv_title.setText(info.getNameString()); return view; }} 2.写一个实体类：
public class PersionInfo implements Serializable { private String nameString; private boolean chick; //标识 public PersionInfo(String nameString) { this.nameString = nameString; } public String getNameString() { return nameString; } public void setNameString(String nameString) { this.nameString = nameString; } public boolean isChick() { return chick; } public void setChick(boolean chick) { this.chick = chick; }} 3.写一个adapter
public class MyAdapter extends BaseAdapter { private Context context; private List<PersionInfo> listinfos; public MyAdapter(Context context, List<PersionInfo> listinfos){ this.context =context; this.listinfos = listinfos; } @Override public int getCount() { // TODO Auto-generated method stub return listinfos.size(); } @Override public Object getItem(int position) { // TODO Auto-generated method stub return listinfos.get(position); } @Override public long getItemId(int position) { // TODO Auto-generated method stub return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { // TODO Auto-generated method stub convertView = LayoutInflater.from(context).inflate(R.layout.listview_item, null); TextView tv = (TextView) convertView.findViewById(R.id.tv); PersionInfo persionInfo = listinfos.get(position); tv.setText(persionInfo.getNameString()); if (persionInfo.isChick()) { convertView.setBackgroundResource(R.drawable.tongcheng_all_bg01); } else { convertView.setBackgroundColor(Color.parseColor("#f4f4f4")); } return convertView; }} 4.adapter所需的list_item.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:minHeight="60dp" android:gravity="center" android:orientation="vertical" > <TextView android:id="@+id/tv" android:layout_width="wrap_content" android:layout_height="match_parent" /></LinearLayout>
Maintivity
/** * * @author yihuanxing * */public class MainActivity extends FragmentActivity implements OnItemClickListener { List<PersionInfo> listinfoInfos=new ArrayList<PersionInfo>(); private ListView listView; private MyAdapter adapter; private MyFragment myFragment; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); initView(); } /** * 初始化view */ private void initView() { // TODO Auto-generated method stub for (int i = 0; i < 10; i++) { PersionInfo info=new PersionInfo("常用分类"+i); listinfoInfos.add(info); } // listView = (ListView) findViewById(R.id.listview); //默认 listinfoInfos.get(0).setChick(true); adapter = new MyAdapter(this, listinfoInfos); listView.setAdapter(adapter); listView.setOnItemClickListener(this); //创建MyFragment对象 myFragment = new MyFragment(); FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); fragmentTransaction.replace(R.id.fragment_container, myFragment); Bundle mBundle=new Bundle(); mBundle.putSerializable("info", listinfoInfos.get(0)); myFragment.setArguments(mBundle); fragmentTransaction.commit(); } @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { PersionInfo info = listinfoInfos.get(position); for (int i = 0; i < listinfoInfos.size(); i++) { if(listinfoInfos.get(i).getNameString().equals(info.getNameString())){ listinfoInfos.get(i).setChick(true); }else { listinfoInfos.get(i).setChick(false); } } adapter.notifyDataSetChanged(); // //创建MyFragment对象 myFragment = new MyFragment(); FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); fragmentTransaction.replace(R.id.fragment_container, myFragment); Bundle mBundle=new Bundle(); mBundle.putSerializable("info", listinfoInfos.get(position)); myFragment.setArguments(mBundle); fragmentTransaction.commit(); }} 6 main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical" > <RelativeLayout android:id="@+id/jzfw_top_layout" android:layout_width="match_parent" android:layout_height="42dp" android:background="@drawable/home_title" android:gravity="center_vertical" > <TextView android:id="@+id/jzfw_top_layout_02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:text="仿京东分类" android:textColor="#ffffff" android:textSize="20sp" /> </RelativeLayout> <View android:layout_width="match_parent" android:layout_height="1dp" android:background="#cdcdcd" /> <LinearLayout android:layout_width="match_parent" android:layout_height="match_parent" android:background="#fbfbfb" android:orientation="horizontal" > <ListView android:id="@+id/listview" android:layout_width="0dp" android:layout_height="match_parent" android:scrollbars="none" android:layout_weight="1.0" android:background="#f4f4f4" /> <View android:layout_width="1dp" android:layout_height="match_parent" android:background="#cdcdcd" /> <FrameLayout android:id="@+id/fragment_container" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="3.0" /> </LinearLayout></LinearLayout>
