像datepicker一样，也有timepicker。

同样有timepickerdialog

所用到的方法还是一样，监听时间选择器的变化。

        findViewById(R.id.btn_time).setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == R.id.btn_time) {
            Calendar calendar = Calendar.getInstance();
            TimePickerDialog dialog = new TimePickerDialog(this, this,
                    calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE), true);
            dialog.show();
        }
    }

    @Override
    public void onTimeSet(TimePicker view, int hourOfDay, int minute) {
        String desc = String.format("您选择的时间是%d时%d分", hourOfDay, minute);
        tv_time.setText(desc);
    }

    public static void startHome(Context mContext) {
        Intent intent = new Intent(mContext, class_5_1_2d.class);
        mContext.startActivity(intent);
    }

}
