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:
