Android日期选择控件效果如下:

调用的代码:

@OnClick(R.id.btn0)

public void btn0() {

final AlertDialog dialog = new AlertDialog.Builder(context).create();

dialog.show();

Window window = dialog.getWindow();

window.setContentView(R.layout.dialog_change_date);

window.setBackgroundDrawable(new ColorDrawable(0x00000000)); // 处理5.0以上对话框的白边问题

window.setGravity(Gravity.BOTTOM);

final DatePickerView datePickerView = (DatePickerView) window.findViewById(R.id.datePickerView);

//打开页面时需要选中的日期 TODO

datePickerView.setDate(2015, 5, 11);

// datePickerView.setDate(birthdayArray[0], birthdayArray[1], birthdayArray[2]);

final int[] birthdayArray = new int[3];

datePickerView.addOnSelectedChangingListener(new DatePickerView.OnSelectedChangedListener() {

@Override

public void OnSelectedChanged(int[] oldValue, int[] newValue) {

birthdayArray[0] = newValue[0];

birthdayArray[1] = newValue[1];

birthdayArray[2] = newValue[2];

}

});

window.findViewById(R.id.tvCancel).setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

dialog.dismiss();

}

});

window.findViewById(R.id.tvOK).setOnClickListener(new View.OnClickListener() {

@Override

public void onClick(View view) {

dialog.dismiss();

btn0.setText(birthdayArray[0] + "年" + birthdayArray[1] + "月" + birthdayArray[2] + "日");

}

});

}
