android 仿美团选择城市界面
2024-05-19 00:08:11
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
*/
public MyDbHelper(Context context, String name, SQLiteDatabase.CursorFactory factory,
int version) {// 必须通过super调用父类当中的构造函数
super(context, name, null, version);
this.myContext = context;
}public MyDbHelper(Context context, String name, int version) {this(context, name, null, version);
}public MyDbHelper(Context context, String name) {this(context, name, DB_VERSION);
}public MyDbHelper(Context context) {this(context, DB_PATH + DB_NAME);
}public void createDataBase() throws IOException {boolean dbExist = checkDataBase();
Log.e("database",String.valueOf(dbExist));
if (dbExist) {// 数据库已存在，do nothing.
} else {// 创建数据库
try {File dir = new File(DB_PATH);
if (!dir.exists()) {dir.mkdirs();
}File dbf = new File(DB_PATH + DB_NAME);
if (dbf.exists()) {dbf.delete();
}SQLiteDatabase.openOrCreateDatabase(dbf, null);
// 复制asseets中的db文件到DB_PATH下
copyDataBase();
} catch (IOException e) {throw new Error("数据库创建失败");
}}
}// 检查数据库是否有效
private boolean checkDataBase() {SQLiteDatabase checkDB = null;
String myPath = DB_PATH + DB_NAME;
try {checkDB = SQLiteDatabase.openDatabase(myPath, null,
SQLiteDatabase.OPEN_READONLY);
} catch (SQLiteException e) {// database does't exist yet.
}if (checkDB != null) {checkDB.close();
}return checkDB != null ? true : false;
}/**
* Copies your database from your local assets-folder to the just created
* empty database in the system folder, from where it can be accessed and
* handled. This is done by transfering bytestream.
* */
private void copyDataBase() throws IOException {// Open your local db as the input stream
InputStream myInput = myContext.getAssets().open(ASSETS_NAME);
// Path to the just created empty db
String outFileName = DB_PATH + DB_NAME;
// Open the empty db as the output stream
OutputStream myOutput = new FileOutputStream(outFileName);
// transfer bytes from the inputfile to the outputfile
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer)) > 0) {myOutput.write(buffer, 0, length);
}// Close the streams
myOutput.flush();
myOutput.close();
myInput.close();
}// 复制assets下的大数据库文件时用这个
private void copyBigDataBase() throws IOException {InputStream myInput;
String outFileName = DB_PATH + DB_NAME;
OutputStream myOutput = new FileOutputStream(outFileName);
for (int i = ASSETS_SUFFIX_BEGIN; i < ASSETS_SUFFIX_END + 1; i++) {myInput = myContext.getAssets().open(ASSETS_NAME + "." + i);
byte[] buffer = new byte[1024];
int length;
while ((length = myInput.read(buffer)) > 0) {myOutput.write(buffer, 0, length);
}myOutput.flush();
myInput.close();
}myOutput.close();
}@Override
public synchronized void close() {if (myDataBase != null) {myDataBase.close();
}super.close();
}
第二步直接使用了创建城市列表 读取数据库然后，进行保存数据。（有的代码截取的不完整，请见谅！）
private ArrayList<City> getCityList() {
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;
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;
就是让所绘制的文字在X方向上显示在View的中间，而float yPos = singleHeight * i + singleHeight;就是来改变每个文字的Y坐标使其沿着竖直方向去绘制文字
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
这个自定义view的代码如下
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);
}
这样右边的效果就实现了。
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;
}
从数据中取出城市的数据包括城市 加上城市的拼音然后保存到集合 最后用集合的排序进行A--Z进行排序。
/**
* 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;
}}
};
然后 这个本来就该结束了，但是我这个从数据库查询不到信息，数据库存在 然后用 sqlite export 打开进行sql查询发现可以查到数据但是在代码中却发现不了这张表 最后只能发大招（笨人有笨人的方法）手动添加数据到map 然后 从map遍历得到城市 城市拼音 ，最后添加到集合。附上手写的（手快残了感觉）
