Android仿京东分类效果

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>
