本文實例為大家分享了Android仿京東分類效果展示的具體代碼，供大家參考，具體內容如下

1.寫一個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);    //得到數據    PersionInfo info = (PersionInfo) getArguments().getSerializable("info");    tv_title.setText(info.getNameString());    return view;  }}

2.寫一個實體類：

public class PersionInfo implements Serializable {  private String nameString;  private boolean chick;  //標識  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.寫一個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("常用分類"+i);      listinfoInfos.add(info);    }    //    listView = (ListView) findViewById(R.id.listview);    //默認    listinfoInfos.get(0).setChick(true);    adapter = new MyAdapter(this, listinfoInfos);    listView.setAdapter(adapter);    listView.setOnItemClickListener(this);    //創建MyFragment對象    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();    //    //創建MyFragment對象    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="仿京東分類"      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>
