這篇文章主要介紹了Android實現(xiàn)的ListView分組布局改進(jìn)的方法,結(jié)合實例形式分析了Android針對ListView的分組布局相關(guān)操作技巧,需要的朋友可以參考下

本文實例講述了Android實現(xiàn)的ListView分組布局改進(jìn)方法。分享給大家供大家參考，具體如下：

由于是在網(wǎng)上轉(zhuǎn)載的一篇文章，在這里就不多說廢話了，首先看一下最終的效果圖：

然后是實現(xiàn)該ListView布局的主要代碼：

1、程序主界面 SeparateListView.java

package whu.iss.wuxianglong;
import java.util.ArrayList;
import java.util.List;
import android.app.Activity;
import android.content.Context;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class SeparateListView extends Activity {
  ListView listView;
  MyAdapter myAdapter;
  public List<String> listTag = new ArrayList<String>();
  /** Called when the activity is first created. */
  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    listView = (ListView) findViewById(R.id.list);
    myAdapter = new MyAdapter(this,
        android.R.layout.simple_expandable_list_item_1, getData());
    listView.setAdapter(myAdapter);
  }
  private List<String> getData() {
    List<String> data = new ArrayList<String>();
    int i = 0;
    data.add("A");
    listTag.add("A");
    data.add("aa試數(shù)據(jù)" + (i++));
    data.add("a試數(shù)據(jù)" + (i++));
    data.add("aa試數(shù)據(jù)" + (i++));
    listTag.add("B");
    data.add("B");
    data.add("bb試數(shù)據(jù)" + (i++));
    data.add("b試數(shù)據(jù)" + (i++));
    data.add("b試數(shù)據(jù)" + (i++));
    data.add("b試數(shù)據(jù)" + (i++));
    listTag.add("C");
    data.add("C");
    data.add("c測試數(shù)據(jù)" + (i++));
    data.add("c測試數(shù)據(jù)" + (i++));
    listTag.add("D");
    data.add("D");
    data.add("d測試數(shù)據(jù)" + (i++));
    data.add("d測試數(shù)據(jù)" + (i++));
    data.add("d測試數(shù)據(jù)" + (i++));
    listTag.add("E");
    data.add("E");
    data.add("e測試數(shù)據(jù)" + (i++));
    data.add("e測試數(shù)據(jù)" + (i++));
    data.add("e測試數(shù)據(jù)" + (i++));
    listTag.add("F");
    data.add("F" );
    data.add("f測試數(shù)據(jù)" + (i++));
    return data;
  }
  class MyAdapter extends ArrayAdapter<String> {
    public MyAdapter(Context context, int textViewResourceId,
        List<String> objects) {
      super(context, textViewResourceId, objects);
    }
    @Override
    public boolean areAllItemsEnabled() {
      return false;
    }
    @Override
    public boolean isEnabled(int position) {
      // 如果-開頭，則該項不可選
      return !listTag.contains(getItem(position));
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
      View view = convertView;
     //根據(jù)標(biāo)簽類型加載不通的布局模板
      if(listTag.contains(getItem(position))){
        //如果是標(biāo)簽項
        view = LayoutInflater.from(getContext()).inflate(R.layout.group_list_item_tag, null);
      }else{
        //否則就是數(shù)據(jù)項
        view = LayoutInflater.from(getContext()).inflate(R.layout.group_list_item, null);
      }
     //顯示名稱
      TextView textView = (TextView) view.findViewById(R.id.group_list_item_text);
      textView.setText(getItem(position));
     //返回重寫的view
      return view;
    }
  }
}

2、程序主界面布局文件main.xml

<?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"
  >
  <ListView
    android:id="@+id/list"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content">
  </ListView>
</LinearLayout>

3、ListView中數(shù)據(jù)部分樣式布局文件group_list_item.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="horizontal"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:padding="5dip">
  <ImageView
    android:src="@drawable/icon"
    android:layout_width="50px"
    android:layout_height="50px">
  </ImageView>
  <TextView
    android:id="@+id/group_list_item_text"
    android:layout_width="wrap_content"
    android:layout_height="fill_parent"
    android:paddingLeft="5dip"
    android:gravity="center_vertical">
  </TextView>
</LinearLayout>

4、ListView中分組標(biāo)志行的樣式布局文件group_list_item_tag.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  android:layout_width="fill_parent"
  android:layout_height="wrap_content"
  android:background="#555555"
  android:paddingLeft="10dip">
  <TextView
    android:id="@+id/group_list_item_text"
    android:layout_width="wrap_content"
    android:layout_height="20dip"
    android:textColor="#ffffff"
    android:gravity="center_vertical">
  </TextView>
</LinearLayout>
