Android：dialog日期控件功能的实现

1.样式中添加Button

 <Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="呀~"
        android:id="@+id/data"
        android:layout_below="@+id/ck"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="34dp" />

2.java代码如下

 private Button data;
   data= (Button) findViewById(R.id.data);
        data.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                Calendar c=Calendar.getInstance();
                int year=c.get(Calendar.YEAR);
                int month=c.get(Calendar.MONTH);
                int day=c.get(Calendar.DAY_OF_MONTH);

                DatePickerDialog d=new DatePickerDialog(Main4Activity.this, new DatePickerDialog.OnDateSetListener() {
                    @Override
                    public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                        Toast.makeText(Main4Activity.this, year+"/"+(monthOfYear+1)+"/"+dayOfMonth, Toast.LENGTH_SHORT).show();
                    }
                },year,month,day);
                d.show();

            }
        });
