自定义DatePicker及DatePickerDialog

利用开源项目AndroidWheel，地址：https://code.google.com/p/android-wheel/，自定义DatePicker及DatePickerDialog

CustomDatePicker布局

使用方法

@Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        findViewById(R.id.tv_click).setOnClickListener(new OnClickListener() {            @Override            public void onClick(View arg0) {                CustomDatePickerDialog dialog = new CustomDatePickerDialog(MainActivity.this, Calendar.getInstance());                dialog.addDateListener(new onDateListener() {                    @Override                    public void dateFinish(Calendar c) {                        Toast.makeText(getApplicationContext(), c.getTime().toLocaleString(), Toast.LENGTH_SHORT).show();                    }                });                dialog.show();            }        });        CustomDatePicker cdp = (CustomDatePicker) findViewById(R.id.cdp);        cdp.addChangingListener(new ChangingListener() {            @Override            public void onChange(Calendar c) {                Toast.makeText(getApplicationContext(), c.getTime().toLocaleString(), Toast.LENGTH_SHORT).show();            }        });    }
