2. 布局文件

1)显示筛选的标题

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

        android:divider="@null"
        android:layoutAnimation="@anim/layout_anim_controller" />
</LinearLayout>

2)dialog里的列表

<?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="@color/White"
    android:gravity="center"
    android:orientation="vertical" >

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="50dp"
        android:background="@color/White"
        android:gravity="center"
        android:weightSum="2"
        android:orientation="horizontal" >
        <TextView 
            android:id = "@+id/tvDialogTitle"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:gravity="center"
            android:layout_weight="1"
            android:textSize="@dimen/title_2_text_size"
        />
        <View
            android:layout_width="2px"
            android:layout_height="match_parent"
            android:layout_marginTop="0dp"
            android:background="@color/divider_line_color" />
        <TextView 
            android:id = "@+id/tvOk"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/ok"
            android:gravity="center"
            android:textColor="@color/vi_color"
            android:layout_weight="1"
            android:textSize="@dimen/title_2_text_size"
        />
    </LinearLayout>
    <View
            android:layout_width="match_parent"

    <ListView
        android:id="@+id/lvFilter"
        android:layout_width="fill_parent"
        android:layout_height="250dp"
        android:layout_gravity="center"
        android:cacheColorHint="#00000000" >
    </ListView>

</LinearLayout>

3. java 代码实现

比较关键的部分已标色,觉得有用的可以自己研究下,改改就可以直接用了.

public class FilterActivity extends Activity implements OnClickListener {

    private static final String TAG = "FilterActivity";
    public static final String FILTER_STRING = "filter_string";
    public static final int FILTER_RESULT_CODE = 99;
    private AlertDialog builder;
    private ListView dialogLv;
    private TextView mTvCity;
    private TextView mTvDialogTitle;
    private Context mContext;
    private ListView mLvFilterTitles;
    
    private int mFilterItemIndex = -1;
    private ArrayList<FilterItem> mFilterItems = new ArrayList<FilterItem>();
    private ArrayList<String> mHospitalNames = null;
    private ArrayList<Hospital> mHospitalList = null;
    private FilterTitleAdapter adapter;
    private FilterTitleAdapter filterTitleAdapter;
    private TextView mTvOk;
    private ImageView mIvBack;
    private String mFilterString;
    private HashMap<String, String> mFilterKeyMap = new HashMap<String,String>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_filter);

        mContext = this;
        initFilterKeyMap();
        mLvFilterTitles = (ListView)findViewById(R.id.lvFilterTitles);
        mTvOk = (TextView)findViewById(R.id.tvOk);
        mIvBack = (ImageView)findViewById(R.id.arrowLeftImg);        
        mTvOk.setOnClickListener(this);
        mIvBack.setOnClickListener(this);
        filterTitleAdapter = new FilterTitleAdapter();
        mLvFilterTitles.setAdapter(filterTitleAdapter);
        mLvFilterTitles.setOnItemClickListener(new OnItemClickListener(){

            @Override
            public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                mFilterItemIndex = position; //标记位置以便返回选中值                   
                buildDialog();
                }            
        });
    }
private void buildDialog() { builder = new AlertDialog.Builder(this).create(); builder.show(); LayoutInflater inflater = LayoutInflater.from(this); final View viewDialog = inflater.inflate(R.layout.dialog_filter, null); mTvDialogTitle = (TextView)viewDialog.findViewById(R.id.tvDialogTitle); builder.setContentView(viewDialog); builder.getWindow().setGravity(Gravity.BOTTOM); dialogLv = (ListView) viewDialog.findViewById(R.id.lvFilter); TextView dialogOk = (TextView) viewDialog.findViewById(R.id.tvOk); dialogOk.setOnClickListener(new OnClickListener(){ @Override public void onClick(View arg0) { builder.dismiss(); } }); String titleName = mFilterItems.get(mFilterItemIndex).name; String titleEName = mFilterItems.get(mFilterItemIndex).eName; mTvDialogTitle.setText(titleName); // 这个listview的用法没啥好说的,在这用的是android自带的适配模式
dialogLv.setAdapter(
new ArrayAdapter<String>(mContext, android.R.layout.simple_list_item_1, getDialogLvData(titleEName))); dialogLv.setOnItemClickListener(new OnItemClickListener(){ @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { TextView tv = (TextView)viewDialog.findViewById(view.getId()); tv = (TextView)view.findViewById(android.R.id.text1); Toast.makeText(mContext, "点了 "+ position+ " "+tv.getText(), 0).show(); //这里在点击后,更新上一层listview里的数据,这样就达到同步的效果了
mFilterItems.get(mFilterItemIndex).content
= (String) tv.getText(); filterTitleAdapter.notifyDataSetChanged(); } }); } private void initFilterKeyMap(){ mFilterKeyMap.put("city", "城市"); mFilterKeyMap.put("sex", "性别"); mFilterKeyMap.put("star_level", "星级"); mFilterKeyMap.put("age", "年龄"); mFilterKeyMap.put("hospital", "医院"); } private List<String> getDialogLvData(String key){ List<String> data = new ArrayList<String>(); switch (key){ case "city": data.add("深圳"); break; case "sex": data.add("男"); data.add("女"); break; case "star_level": data.add("1"); data.add("2"); data.add("3"); data.add("4"); data.add("5"); break; case "age": data.add("20 - 29"); data.add("30 - 39"); break; case "hospital": break; } return data; } private class FilterTitleAdapter extends BaseAdapter { public FilterTitleAdapter() { super(); for(Map.Entry<String, String> entry : mFilterKeyMap.entrySet()){ FilterItem item = new FilterItem(); item.name = entry.getValue(); item.eName = entry.getKey(); mFilterItems.add(item) ; } } @Override public int getCount() { return mFilterItems.size(); } @Override public FilterItem getItem(int position) { return mFilterItems.get(position); } @Override public long getItemId(int position) { return position; } @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null){ holder = new ViewHolder(); convertView = View.inflate(mContext, R.layout.list_item_filter_title, null); holder.mTvFilterName = (TextView) convertView.findViewById(R.id.filterItemText); holder.mTvFilterContent = (TextView) convertView.findViewById(R.id.filterItemContent); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } FilterItem fi = mFilterItems.get(position); holder.mTvFilterName.setText(fi.name); holder.mTvFilterContent.setText(fi.content); return convertView; } } private class ViewHolder { TextView mTvFilterContent; TextView mTvFilterName; } @Override public void onClick(View v) { switch (v.getId()) { case R.id.arrowLeftImg: this.onBackPressed(); break; case R.id.tvOk: //返回上一界面并传回数据 getFilterString(); Intent i; i = this.getIntent(); i.putExtra(FILTER_STRING, mFilterString); this.setResult(FILTER_RESULT_CODE, i); finish(); break; default: break; } } }
