android 仿美团选择城市界面

最近，需要搞一个小功能，仿照美团外卖那种切换城市的小功能，开始觉得还挺简单，但是后来仔细分析还是有点小复杂，但克服困难，参考参考资料也算大功告成了。废话就到这里，然后开始撸代码。

第一步 总想找点资料 ，全国城市的数据库，要是没有还得自己搞数据库，干脆偷下懒直接拿过来用吧（嘿嘿）附件如下 导入到自己的项目中直接使用吧

第二就要写数据库的帮助类了 如下直接贴上代码（主要的部分）注释有的。

// 用户数据库文件的版本
private static final int DB_VERSION = 1;
// 数据库文件目标存放路径为系统默认位置，cn.arthur.examples 是你的包名
private static String DB_PATH = "/data/data/com.baidu.facetoface/databases/";
/*
 * //如果你想把数据库文件存放在SD卡的话 private static String DB_PATH =
 * android.os.Environment.getExternalStorageDirectory().getAbsolutePath() +
 * "/arthurcn/drivertest/packfiles/";
 */
private static String DB_NAME = "meituan_cities.db";
private static String ASSETS_NAME = "meituan_cities.db";
private SQLiteDatabase myDataBase = null;
private final Context myContext;

/**
 * 如果数据库文件较大，使用FileSplit分割为小于1M的小文件 此例中分割为 hello.db.101 hello.db.102
 * hello.db.103
 */
// 第一个文件名后缀
private static final int ASSETS_SUFFIX_BEGIN = 101;
// 最后一个文件名后缀
private static final int ASSETS_SUFFIX_END = 103;

/**
 * 在SQLiteOpenHelper的子类当中，必须有该构造函数
 *
 * @param context
 *            上下文对象
 * @param name
 *            数据库名称
 * @param factory
 *            一般都是null
 * @param version
 *            当前数据库的版本，值必须是整数并且是递增的状态

                int version) {// 必须通过super调用父类当中的构造函数
    super(context, name, null, version);

        e.printStackTrace();
    }

    Collections.sort(list, comparator);
    return list;

第三步 地基都准备好了，开始搭房子了。首先分析一下这个界面的实现。

180002d1x1o1sx2vs3o9zf.bmp这个界面从整体上来说包括三大部分第一部分就是最上方的一个EditText，第二部分就是最右边的自定义View，第三部分是EditText下方的ListView，这里EditText的主要作用就是筛选城市，接着我们一点一点的去实现上面的效果。

实现这样一个效果就是滑动最右边的自定义View然后界面中间的TextView去展示所滑到的字母，这里就要去自定义一个View了，首先来分析下思路：

①需要用canvas的drawText方法将：“定位”、最近、热门“、全部、A-Z这些数据画出来，怎么去按照上述图片的样子去绘画这些数据呢？首先需要获得每个字符的高度，怎么获得？用View的高度除以字符的个数就可以得到每个字符的高度，然后绘制时通过控制Y坐标不断的增加从而使数据沿着竖直方向去绘制，在自定义的View中它的实现代码如下

if (showBkg) {//是否显示背景色 触摸后那个阴影效果
    canvas.drawColor(Color.parseColor("#10000000"));
}
int height = getHeight();
int width = getWidth();
int singleHeight = height / b.length;//b 存放字母的数组 
for (int i = 0; i < b.length; i++) {paint.setColor(Color.parseColor("#515151"));
    paint.setTypeface(Typeface.DEFAULT_BOLD);
    paint.setAntiAlias(true);
    if (i == choose) {paint.setColor(Color.parseColor("#3399ff"));
        paint.setFakeBoldText(true);
    }float xPos = width / 2 - paint.measureText(b[i]) / 2;
    float yPos = singleHeight * i + singleHeight;
    canvas.drawText(b[i], xPos, yPos, paint);
    paint.reset();
}

float xPos = width / 2 - paint.measureText(b[i]) / 2;

在滑动时怎样通知Activity当前滑动到哪儿了？

这里是通过一个监听的方式，在Activity中注册了自定义View的监听，然后在View滑动的时候将数据回调给Activity

OnTouchingLetterChangedListener onTouchingLetterChangedListener;
String[] b = { "#", "A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K",
        "L", "M", "N", "O", "P", "Q", "R", "S", "T", "U", "V", "W", "X",
        "Y", "Z" };
int choose = -1;
Paint paint = new Paint();
boolean showBkg = false;

public LetterSelectView(Context context, AttributeSet attrs, int defStyle) {super(context, attrs, defStyle);
}public LetterSelectView(Context context, AttributeSet attrs) {super(context, attrs);
}public LetterSelectView(Context context) {super(context);
}@Override
protected void onDraw(Canvas canvas) {super.onDraw(canvas);
    if (showBkg) {//是否显示背景色 触摸后那个阴影效果
        canvas.drawColor(Color.parseColor("#10000000"));
    }int height = getHeight();
    int width = getWidth();
    int singleHeight = height / b.length;//b 存放字母的数组
    for (int i = 0; i < b.length; i++) {paint.setColor(Color.parseColor("#515151"));
        paint.setTypeface(Typeface.DEFAULT_BOLD);
        paint.setAntiAlias(true);
        if (i == choose) {paint.setColor(Color.parseColor("#3399ff"));
            paint.setFakeBoldText(true);
        }float xPos = width / 2 - paint.measureText(b[i]) / 2;
        float yPos = singleHeight * i + singleHeight;
        canvas.drawText(b[i], xPos, yPos, paint);
        paint.reset();
    }}@Override
public boolean dispatchTouchEvent(MotionEvent event) {final int action = event.getAction();
    final float y = event.getY();
    final int oldChoose = choose;
    final OnTouchingLetterChangedListener listener = onTouchingLetterChangedListener;
    final int c = (int) (y / getHeight() * b.length);
    switch (action) {case MotionEvent.ACTION_DOWN:showBkg = true;
            if (oldChoose != c && listener != null) {if (c >= 0 && c <= b.length) {listener.onTouchingLetterChanged(b[c]);
                    choose = c;
                    invalidate();
                }}break;
        case MotionEvent.ACTION_MOVE:if (oldChoose != c && listener != null) {if (c >= 0 && c <= b.length) {listener.onTouchingLetterChanged(b[c]);
                    choose = c;
                    invalidate();
                }}break;
        case MotionEvent.ACTION_UP:showBkg = false;
            choose = -1;
            invalidate();
            break;
    }return true;
}@Override
public boolean onTouchEvent(MotionEvent event) {return super.onTouchEvent(event);
}public void setOnTouchingLetterChangedListener(OnTouchingLetterChangedListener onTouchingLetterChangedListener) {this.onTouchingLetterChangedListener = onTouchingLetterChangedListener;
}public interface OnTouchingLetterChangedListener {void onTouchingLetterChanged(String s);
}

2、ListView数据的展示

ListView数据的展示是这个界面的重点，对于ListView数据的展示我们都知道它是依靠BaseAdapter的，这里也是通过给ListView设置一个适配器从而实现文章刚开始展现的效果，只不过这里的Adapter用了平时再给ListView设置适配器时不常用的两个方法，一个是getViewTypeCount，另外一个是getItemViewType，仔细观察上面的分析图可以发现这个列表共有5种类型的Item①当前定位城市②最近访问城市③热门城市④全部城市(仅仅显示”全部城市“这四个字)⑤也就是这个列表的主角就是显示从数据库中查出的所有的城市。下面来一一分析这个5种Item的实现方法，

第一种item即当前定位城市，这个item就是用百度定位来定位用户当前所在城市，这个布局没什么可说的。

之前使用百度的地图定位，然而发现这个定位总是实现不了，而且总出现错误找不到文件。浪费好长时间直接换了高德地图定位成功。这个热门城市的类型就一个textView界面不是很好看，如果需要可以使用girdView效果会好看点。下面附上这个adapter的代码。

private LayoutInflater inflater;
private List<City> list;
final int VIEW_TYPE = 3;

public ListAdapter(Context context, List<City> list) {this.inflater = LayoutInflater.from(context);
    this.list = list;
    alphaIndexer = new HashMap<String, Integer>();
    sections = new String[list.size()];
    for (int i = 0; i < list.size(); i++) {// 当前汉语拼音首字母
        String currentStr = getAlpha(list.get(i).getPinyi());
        // 上一个汉语拼音首字母，如果不存在为“ ”
        String previewStr = (i - 1) >= 0 ? getAlpha(list.get(i - 1).getPinyi()) : " ";
        if (!previewStr.equals(currentStr)) {String name = getAlpha(list.get(i).getPinyi());
            alphaIndexer.put(name, i);
            sections[i] = name;
        }}
}@Override
public int getCount() {return list.size();
}@Override
public Object getItem(int position) {return list.get(position);
}@Override
public long getItemId(int position) {return position;
}@Override
public int getItemViewType(int position) {// TODO Auto-generated method stub
    int type = 0;
    if (position == 0) {type = 2;
    } else if (position == 1) {type = 1;
    }return type;
}@Override
public int getViewTypeCount() {// 这里需要返回需要集中布局类型，总大小为类型的种数的下标
    return VIEW_TYPE;
}@Override
public View getView(int position, View convertView, ViewGroup parent) {ViewHolder holder;
    int viewType = getItemViewType(position);
    if (viewType == 1) {if (convertView == null) {topViewHolder = new TopViewHolder();
            convertView = inflater.inflate(R.layout.frist_list_item,
                    null);
            topViewHolder.alpha = (TextView) convertView.findViewById(R.id.alpha);
            topViewHolder.name = (TextView) convertView.findViewById(R.id.lng_city);
            convertView.setTag(topViewHolder);
        } else {topViewHolder = (TopViewHolder) convertView.getTag();
        }/*String locatioName=new Intent().getStringExtra("location");*/
        topViewHolder.name.setText(lngCityName);
       // Log.e("converview",locationName);
        topViewHolder.alpha.setVisibility(View.VISIBLE);
        topViewHolder.alpha.setText("定位城市");

    } else if (viewType == 2) {final ShViewHolder shViewHolder;
        if (convertView == null) {shViewHolder = new ShViewHolder();
            convertView = inflater.inflate(R.layout.search_item, null);
            shViewHolder.editText = (EditText) convertView.findViewById(R.id.sh);
            convertView.setTag(shViewHolder);
        } else {shViewHolder = (ShViewHolder) convertView.getTag();
        }} else {if (convertView == null) {convertView = inflater.inflate(R.layout.list_item, null);
            holder = new ViewHolder();
            holder.alpha = (TextView) convertView.findViewById(R.id.alpha);
            holder.name = (TextView) convertView.findViewById(R.id.name);
            convertView.setTag(holder);
        } else {holder = (ViewHolder) convertView.getTag();
        }if (position >= 1) {holder.name.setText(list.get(position).getName());
            String currentStr = getAlpha(list.get(position).getPinyi());
            String previewStr = (position - 1) >= 0 ? getAlpha(list
                    .get(position - 1).getPinyi()) : " ";
            if (!previewStr.equals(currentStr)) {holder.alpha.setVisibility(View.VISIBLE);
                if (currentStr.equals("#")) {currentStr = "热门城市";
                }holder.alpha.setText(currentStr);
            } else {holder.alpha.setVisibility(View.GONE);
            }}}return convertView;

最关键的怎么得到这个city的集合呢 （这个之前的数据库，以及数据库的帮助类要派上用场。）

private ArrayList<City> getCityLists() {MyDbHelper dbHelper = new MyDbHelper(this);
    ArrayList<City> list = new ArrayList<City>();
    try {dbHelper.createDataBase();
        SQLiteDatabase db = dbHelper.getWritableDatabase();
        Cursor cursor = db.rawQuery("select * from city", null);
        City city;
        while (cursor.moveToNext()) {city = new City(cursor.getString(1), cursor.getString(2));
            list.add(city);
        }cursor.close();
        db.close();
    } catch (IOException e) {e.printStackTrace();
    }Collections.sort(list, comparator);
    return list;
}

/**
 * a-z排序
 */
Comparator comparator = new Comparator<City>() {@Override
    public int compare(City lhs, City rhs) {String a = lhs.getPinyi().substring(0, 1);
        String b = rhs.getPinyi().substring(0, 1);
        int flag = a.compareTo(b);
        if (flag == 0) {return a.compareTo(b);
        } else {return flag;
        }}
};
