android之使用ListView实现多菜单功能

fmms 13年前

我们知道很多软件都有设置菜单项如微信墨迹天气等的设置界面。当设置里有很多选项这时我们可以选择使用ListView实现。

布局文件如下:

    <?xml version="1.0" encoding="utf-8"?>        <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"            android:orientation="vertical"            android:layout_width="fill_parent"            android:layout_height="fill_parent"            android:background="@drawable/splash_background"            >            <ListView android:id="@+id/more_List"                android:layout_width="fill_parent"                android:layout_height="fill_parent"                android:divider="@drawable/list_bottom_line"                android:listSelector="#00000000"                android:cacheColorHint="#00000000">            </ListView>        </LinearLayout>  
很简单只有一个ListView

item的布局:

<?xml version="1.0" encoding="utf-8"?>    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"        android:orientation="horizontal"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:padding="8dip"        android:background="@drawable/list_item"        >        <ImageView android:id="@+id/item_icon"            android:layout_width="wrap_content"            android:layout_height="wrap_content"        />        <TextView android:id="@+id/more_item_text"            android:layout_marginLeft="10dip"            android:textSize="20dip"            android:textColor="#000000"            android:layout_width="wrap_content"            android:layout_height="wrap_content"/>        <ImageView android:id="@+id/item_image"            android:layout_marginTop="5dip"            android:layout_marginLeft="10dip"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:background="@drawable/triangle"        />    </LinearLayout> 
设置成水平布局,一次是图标,文字说明,箭头图标

主要代码如下:
    package com.cloay.news;                import com.cloay.news.bean.MoreAdapter;        import com.cloay.news.service.MainService;        import com.cloay.news.util.AlertDlgUtil;        import com.waps.AppConnect;                import android.content.Intent;        import android.os.Bundle;        import android.view.View;        import android.widget.AdapterView;        import android.widget.AdapterView.OnItemClickListener;        import android.widget.ListView;                /**        * 更多界面包含帮助,关于等。        * @author Cloay        * 2012-3-3        * 下午09:45:12        */        public class MoreActivity extends NewsReaderActivity {            private ListView moreList;            @Override            public void onCreate(Bundle savedInstanceState) {                super.onCreate(savedInstanceState);                setContentView(R.layout.more);                MainService.allActivity.add(this);                moreList = (ListView) findViewById(R.id.more_List);                MoreAdapter adapter = new MoreAdapter(this);                moreList.setAdapter(adapter);                moreList.setOnItemClickListener(new OnItemClickListener() { //为每一个item设置相应的响应                            @Override                    public void onItemClick(AdapterView<?> parent, View view,                            int position, long id) {                        switch(position){                        case 0: //关于                            startActivity(AboutActivity.class);                                    break;                        case 1:                            //分享                            Intent intent=new Intent(Intent.ACTION_SEND);                            intent.setType("text/plain");                            intent.putExtra(Intent.EXTRA_SUBJECT, "分享");                            intent.putExtra(Intent.EXTRA_TEXT, "I would like to share this with you...");                            startActivity(Intent.createChooser(intent, getTitle()));                            break;                        case 2:                            //帮助                            startActivity(HelpActivity.class);                            break;                        case 3:                            //意见反馈                            AppConnect.getInstance(MoreActivity.this).showFeedback();                            break;                        case 4://退出                            AlertDlgUtil.AlertExit(MoreActivity.this);                            break;                        }                    }                });            }            private void startActivity(Class<?>cls){                Intent intent = new Intent(this, cls);                this.startActivity(intent);            }        }  
下面是为ListView提供数据的Adapter:
    package com.cloay.news.bean;                import java.util.ArrayList;        import java.util.List;                import com.cloay.news.R;                import android.content.Context;        import android.view.LayoutInflater;        import android.view.View;        import android.view.ViewGroup;        import android.widget.BaseAdapter;        import android.widget.ImageView;        import android.widget.TextView;                /**        * 为更多中listview提供数据        * @author Cloay        * 2012-3-5        * 下午06:28:14        */        public class MoreAdapter extends BaseAdapter{                    private LayoutInflater inflater;            private Context context;            public static final List<String> more_list = new ArrayList<String>();//为条目提供数据            public MoreAdapter(Context context){                this.context = context;                inflater = LayoutInflater.from(this.context);                more_list.add(context.getResources().getString(R.string.main_square));                more_list.add(context.getResources().getString(R.string.share));                more_list.add(context.getResources().getString(R.string.help_text));                more_list.add(context.getResources().getString(R.string.advice));                more_list.add(context.getResources().getString(R.string.exit_title));            }            @Override            public int getCount() {                return more_list.size();  //条目数量            }                    @Override            public Object getItem(int position) {                return null;            }                    @Override            public long getItemId(int position) {                return 0;            }                    @Override            public View getView(int position, View convertView, ViewGroup parent) {                if (convertView == null) {                      convertView = inflater.inflate(                              R.layout.more_list, null);                  }                 ImageView icon = (ImageView) convertView.findViewById(R.id.item_icon);//设置每个条目的图标                if(0 == position){                    icon.setBackgroundResource(R.drawable.icon_square);                  }else if(1 == position){                    icon.setBackgroundResource(android.R.drawable.ic_menu_share);                }else if(2 == position){                    icon.setBackgroundResource(R.drawable.icon_setting);                }else if(3 == position){                    icon.setBackgroundResource(android.R.drawable.ic_menu_edit);                }else{                    icon.setBackgroundResource(R.drawable.menu_exit);                }                TextView text = (TextView) convertView.findViewById(R.id.more_item_text); //设置条目的文字说明                text.setText(more_list.get(position));                return convertView;            }                }  
运行效果图如下:
